Chapter 2: New in this document The following sections detail what is new in VOSS 5.1.1 and 5.1 in Configuring IP Multicast Routing Protocols on Avaya Virtual Services Platform 4000 Series , NN46251-504. Release 5.1.1 IPv6 MLD group information In this release, you can view information about MLD groups. For more information, see Viewing the MLD group information on page 148. Release 5.1 IPv6 Multicast Listener Discovery Multicast Listener Discovery is a IPv6 multicast host membership discovery protocol.
Release 5.1 only supports SPT. PIM over IPv6 uses the IPv6 unicast routing table for reverse path information about source and RP.
Chapter 3: IP multicast fundamentals IP multicast extends the benefits of Layer 2 multicasting on LANs to WANs. Use multicasting techniques on LANs to help clients and servers find each other. With IP multicast, a source can send information to multiple destinations in a WAN with a single transmission. IP multicast results in efficiency at the source and saves a significant amount of bandwidth.
Overview of IP multicast Note: • PIM is supported with Simplified vIST only, not SPB vIST. However, you do not have to configure Simplified vIST to run PIM or IGMP Snooping in a non-SMLT topology. • LACP is not recommended on SPB NNI MLT links or on the Simplified Virtual IST. After you disable the spbm-config-mode boot flag, you can configure PIM or IGMP Snooping on any VLAN including the vIST VLAN.
IP multicast fundamentals Figure 1: Multicast distribution tree and broadcasting Broadcast and prune methods use multicast traffic to build the distribution tree. Periodically, the source sends or broadcasts data to the extremities of the internetwork to search for active group members. If no local members of the group exist, the router sends a message to the host, removing itself from the distribution tree, and thus pruning the router.
Overview of IP multicast Figure 2: Pruning routers from a distribution tree Reverse path multicast is based on the concept that a multicast distribution tree is built on the shortest path from the source to each subnetwork that contains active receivers. After a datagram arrives on an interface, the router determines the reverse path to the source of the datagram by examining the routing table of known network sources. If the datagram is not on the optimal delivery tree, the router discards it.
IP multicast fundamentals A host system on an IP network sends a message to a multicast group by using the IP multicast address for the group. To receive a message addressed to a multicast group, however, the host must be a member of the group and must reside on a network where that group is registered with a local multicast router. An IP multicast host group can consist of zero or more members and places no restrictions on its membership.
Overview of IP multicast To configure static source groups, you must first globally enable PIM. If you disable PIM, the switch saves all of the configured static source-group entries and deactivates them. After you re-enable PIM, the switch reactivates the static source groups. Static source groups ensure that the multicast route (mroute) records remain in the distribution tree.
IP multicast fundamentals Internet Group Management Protocol A host uses IGMP to register group memberships with the local querier router to receive datagrams sent to this router targeted to a group with a specific IP multicast address. A router uses IGMP to learn the existence of group members on networks to which it directly attaches. The router periodically sends a general query message to each of its local networks.
Internet Group Management Protocol for the group immediately after it receives a leave message, without issuing a query to check if other group members exist on the network. Fast leave alleviates the network from additional bandwidth demand after a customer changes television channels.
IP multicast fundamentals forwards multicast data only to the participating group members and to the multicast routers within the VLAN. The multicast routing functionality can coexist with IGMP snoop on the same switch, but you can configure only one of IGMP snoop or an IP multicast routing protocol, excluding IGMP, on the same VLAN. Multicast group trace for IGMP snoop Use this feature to monitor the multicast group trace for an IGMP snoop-enabled switch .
Internet Group Management Protocol The Record Type of a current-state record has one of the following two values: • MODE_IS_INCLUDE — Indicates that the interface has a filter mode of include for the specified multicast address. The source address fields in this group record contain the source list of the interface for the specified multicast address. • MODE_IS_EXCLUDE — Indicates that the interface has a filter mode of exclude for the specified multicast address.
IP multicast fundamentals • group timer • filter mode (source records) Each source record is of the form source address or source timer. If all sources within a given group are desired, an empty source record list is kept with filter-mode set to EXCLUDE. This means hosts on this network want all sources for this group to be forwarded. This is the IGMPv3 equivalent to a IGMPv1 or IGMPv2 group join.
Internet Group Management Protocol there are no sources in the global ssm-map, the message is discarded. These reports are processed with no restriction as an IGMPv3 report. • IGMPv2 leave for groups within SSM range translate to IGMPv3 reports with one group record and type BLOCK{S1,S2,...}. The source list is obtained from the global ssm-map. If there are no sources in the global ssm-map, the message is discarded. These reports are processed with no restriction as an IGMPv3 report.
IP multicast fundamentals When a LEAVE message is received, you must check if the member that sent this message is the last reporter for the group. If it is the last reporter, switch to INCLUDE mode if sources are available (if no sources are available the port is deleted). Else, delete the member. No group and source specific queries or group specific queries are sent. Important: To use IGMPv3 fast leave feature, you must first enable the explicit host tracking feature.
IGMP Layer 2 Querier is out of SSM range and it is a v3 message, the switch drops the message; if it is a v2 message, PIM-SM or IGMP snoop processes handle the message. After the switch receives an IGMPv2 leave message, and the group address in it is within SSM range, the switch sends the group-and-source specific query. If the group address is not within the SSM range, the switch sends the group specific query.
IP multicast fundamentals You must enable Layer 2 querier and configure an IP address for the querier before it can originate IGMP query messages. If a multicast router exists on the network, the switch automatically disables the Layer 2 querier. In a Layer 2 multicast network, enable Layer 2 querier on only one of the switches in the VLAN. A Layer 2 multicast domain supports only one Layer 2 querier. No querier election exists.
Multicast access control Multicast access control Multicast access control is a set of features that operate with standard existing multicast protocols. You can configure multicast access control for an IP multicast-enabled port or VLAN with an access control policy that consists of several IP multicast groups. You can use this feature to restrict access to certain multicast streams and to protect multicast streams from spoofing (injecting data to the existing streams).
IP multicast fundamentals on the ingress interface to the multicast source. The deny-tx access policy performs the opposite function of the allow-only-tx access policy. Therefore, the deny-tx access policy and the allow-onlytx access policy cannot exist on the same interface at the same time. For example, in Figure 3: Data flow using deny-tx policy on page 34, a VLAN 1, the ingress VLAN, uses a deny-tx access policy.
Multicast access control VLANs from participating in an activity involving the specified multicast groups with the deny-both policy. Figure 5: Data flow using deny-both policy allow-only-tx Use the allow-only-tx policy to allow only the matching source to send multicast traffic to the matching group on the interface where you configure the allow-only-tx policy. The interface discards all other multicast data it receives.
IP multicast fundamentals Multicast stream limitation feature You can configure the multicast stream limitation feature to limit the number of multicast groups that can join a VLAN. By limiting the number of concurrent multicast streams, a service provider can, for example, protect the bandwidth on a specific interface and control access to multicast streams. Use multicast stream limitation in an environment where you want to limit users to a certain number of multicast streams simultaneously.
Multicast flow distribution over MLT Multicast routers send multicast router advertisements periodically on all interfaces where you enable multicast forwarding. Multicast routers also send advertisements in response to multicast router solicitations. Multicast router solicitations transmit to the IGMP-MRDISC all-routers multicast group that uses a multicast address of 224.0.0.2. Multicast router solicitations do not transmit if a router needs to discover multicast routers on a directly attached subnet.
IP multicast fundamentals Important: You can configure multicast MAC filtering only for local addresses on a switch. You cannot use this feature to route traffic between switches (for example, you cannot configure it to forward for interfaces that are not local). The multicast MAC is a MAC address where the least significant bit of the most significant byte is 1. The multicast MAC filtering feature is available for Layer 2.
Protocol Independent Multicast-Sparse Mode If you use IGMP snooping on the VLAN, ensure the IGMP version on the multicast hosts or other network devices is either the same as the version on the VLAN, or enable compatibility mode. Multicast virtualization does not support PIM. The switch supports IGMP with PIM only in the Global Router.
IP multicast fundamentals Each PIM-SM domain requires the following routers: • designated router (DR) • rendezvous point (RP) router • bootstrap router (BSR) Although a PIM-SM domain can use only one active RP router and one active BSR, you can configure additional routers as a candidate RP (C-RP) router and as a candidate BSR (C-BSR). Candidate routers provide backup protection in case the primary RP router or BSR fails.
Protocol Independent Multicast-Sparse Mode Static rendezvous point router You can configure a static entry for an RP router with static RP. This feature avoids the process of selecting an active RP from the list of candidate RPs and dynamically learning about RPs through the BSR mechanism. Static RP-enabled switches cannot learn about RPs through the BSR because the switch loses all dynamically learned BSR information and ignores BSR messages.
IP multicast fundamentals Important: To reduce convergence times, create only one static RP for each group. The more static RPs you configure for redundancy, the more time PIM requires to rebuild the mroute table and associate RPs. • Static RP configured on the switch is active as long as the switch uses a unicast route to the static RP network. If the switch loses this route, the static RP is invalidated and the hash algorithm remaps all affected groups.
Protocol Independent Multicast-Sparse Mode Figure 6: Shared tree and shortest-path tree Receiver joining a group The following steps describe how a receiver joins a multicast group: 1. A receiver multicasts an IGMP host membership message to the group that it wants to join. 2. After the last-hop router (the DR), normally the PIM router with the highest IP address for that VLAN, receives the IGMP message for a new group join, the router looks up the associated elected RP with responsibility for the group.
IP multicast fundamentals Receiver leaving a group Before it leaves a multicast group, a receiver sends an IGMP leave message to the DR. If all directly connected members of a multicast group leave or time out, and no downstream members remain, the DR sends a prune message upstream and PIM-SM deletes the route entry after that entry times out. When the system ages PIM mroutes, it does not clear the (S,G) entry for an inactive route immediately after the expiration period.
Protocol Independent Multicast-Sparse Mode Required elements for PIM-SM operation For PIM-SM to operate, the following elements must exist in the PIM-SM domain: • You must enable an underlying unicast routing protocol for the switch to provide routing table information to PIM-SM. • You must configure an active BSR to send bootstrap messages to all PIM-v2 configured switches and routers to enable them to learn group-to-RP mapping.
IP multicast fundamentals Figure 7: PIM-SM simplified example In the sample configuration, the following events occur: 1. The BSR distributes RP information to all switches in the network. 2. R sends an IGMP membership report to S4. 3. Acting on this report, S4 sends a (*,G) join message to RP. 4. S sends data to G. 5. The DR (S1 in this example) encapsulates the data that it unicasts to RP (S2) in register messages. 6. S2 decapsulates the data, which it forwards to S4. 7. S4 forwards the data to R. 8.
Join and prune messages PIM-SM static source groups You can configure static source groups as static source-group entries in the PIM-SM multicast routing table. PIM-SM cannot prune these entries from the distribution tree. For more information about static source groups, see Static source groups on page 22. Join and prune messages The DR sends join and prune messages from a receiver toward an RP for the group to either join the shared tree or remove (prune) a branch from it.
IP multicast fundamentals The following rules apply: • If a VLAN receives traffic from the IST link, it cannot forward on the split multilink trunk link or the edge for the same VLAN. • If one side of the SMLT link toward the receiver is down, such that the traffic cannot be forwarded directly down the SMLT link from the router on which traffic is ingressing, the IST Peer MUST forward that traffic it receives over the IST link down its side of the SMLT toward the receiver.
Protocol Independent Multicast-Source Specific Multicast Protocol Independent Multicast-Source Specific Multicast Source Specific Multicast optimizes PIM-SM by simplifying the many-to-many model. Because most multicast applications distribute content to a group in one direction, SSM uses a one-to-many model that uses only a subset of the PIM-SM features. This model is more efficient and reduces the load on multicast routing devices. SSM only builds source-based SPTs.
IP multicast fundamentals PIM-SSM architecture The following diagram illustrates how the PIM-SSM architecture requires routers to perform the following actions: • support IGMPv3 source-specific host membership reports and queries at the edge routers • initiate PIM-SSM (S,G) joins directly and immediately after receiving an IGMPv3 join report from the designated router • restrict forwarding to SPTs within the SSM address range by all PIM-SSM routers Figure 8: PIM-SSM architecture The following rules apply
Protocol Independent Multicast-Source Specific Multicast • Receive IGMPv2 membership join reports, but only for groups that already use a static (S,G) entry in the SSM channel table. • Send periodic join messages to maintain a steady SSM tree state. • Use standard PIM-SM SPT procedures for unicast routing changes, but ignore rules associated with the SPT for the (S,G) route entry. • Receive prune messages and use standard PIM-SM procedures to remove interfaces from the source tree.
IP multicast fundamentals SSM and IGMPv2 SSM-configured switches can accept reports from IGMPv2 hosts on IGMPv2 interfaces if the group uses an SSM channel table entry. However, the IGMPv2 host groups must exist in the SSM range defined on the switch, which is 232/8 by default. • After the SSM switch receives an IGMPv2 report for a group that is in the SSM channel table, it joins the specified source immediately.
Protocol Independent Multicast-Source Specific Multicast • If you enable dynamic learning for an IGMPv3 host, the SSM channel automatically learns the group. Otherwise, the SSM channel also needs a static entry. The following table summarizes how a switch in PIM-SSM mode works with IGMP if you disable IGMPv3 compatibility. In the following table, references to matching a static SSM channel entry assumes that the entry is enabled. If an entry is disabled, it is treated as though it is disallowed.
IP multicast fundamentals If an IGMPv3 interface receives an IGMPv2 or v1 query, the interface backs down to IGMPv2 or v1. As a result, the interface flushes all senders and receivers on the interface. Configuration limitations Run PIM-SSM on either all switches in the domain or only on the edge routers. If you use a mix of PIM-SSM and PIM-SM switches in the domain, run PIM-SSM on all the edge routers and run PIMSM on all the core routers.
IP multicast network design Important: A device can send register and register-stop messages to a PIM passive interface, but these messages cannot be sent out of that interface. The PIM passive interface maintains information about hosts, through IGMP, that are related to senders and receivers, but the interface does not maintain information about PIM neighbors. You can configure a BSR or an RP on a PIM passive interface.
IP multicast fundamentals in the same subnet sending to the same group. Be aware that these streams have separate hardware forwarding records on the ingress side. 3. Do not configure multicast routing on edge switch interfaces that do not contain multicast senders or receivers. By following this rule, you: • Provide secure control over multicast traffic that enters or exits the interface. • Reduce the load on the switch, as well as the number of routes. This improves overall performance and scalability. 4.
IP multicast network design from candidate RP routers, and then propagate the RP set hop-by-hop to all PIM routers. This must be done before a Join message can be processed. If the PIM router receives a Join message before it learns the RP set, the router drops the Join message and waits for another Join or Prune message to arrive before it creates the multicast router, and propagates the Join messages to the RP.
IP multicast fundamentals Multicast MAC address mapping considerations Like IP, Ethernet has a range of multicast MAC addresses that natively support Layer 2 multicast capabilities. While IP has a total of 28 addressing bits available for multicast addresses, Ethernet has only 23 addressing bits assigned to IP multicast. The Ethernet multicast MAC address space is much larger than 23 bits, but only a subrange of that larger space is allocated to IP multicast.
IP multicast network design switch. To avoid this extra load, Avaya recommends that you manage the IP multicast group addresses used on the network. VSP 4000 does not forward IP multicast packets based on multicast MAC addresses—even when bridging VLANs at Layer 2. Thus, the platform does not encounter this problem. Instead, the platform internally maps IP multicast group addresses to the ports that contain group members.
IP multicast fundamentals You can configure the IGMP version of an interface to version 3 regardless of the PIM or snooping mode. You can configure whether the switch downgrades the version of IGMP to handle older query messages. If the switch downgrades, the host with IGMPv3 only capability does not work. If you do not configure the switch to downgrade the version of IGMP, the switch logs a warning.
IP multicast network design Guidelines for multicast access policies Use the following guidelines when you configure multicast access policies: • Use masks to specify a range of hosts. For example, 10.177.10.8 with a mask of 255.255.255.248 matches hosts addresses 10.177.10.8 through 10.177.10.15. The host subnet address and the host mask must be equal to the host subnet address.
IP multicast fundamentals Protocol Independent Multicast-Sparse Mode guidelines Protocol Independent Multicast-Sparse Mode (PIM-SM) uses an underlying unicast routing information base to perform multicast routing. PIM-SM builds unidirectional shared trees rooted at a RP router for each group and can also create shortest-path trees for each source.
IP multicast network design • As a load sharing option, you can have several RPs in a PIM-SM domain map to different groups. • In order to configure an RP to cover the entire multicast range, configure an RP to use the IP address of 224.0.0.0 and the mask of 240.0.0.0. • Configure an RP to handle a range of multicast groups by using the mask parameter. For example, an entry for group value of 224.1.1.0 with a mask of 255.255.255.192 covers groups 224.1.1.0 to 224.1.1.63.
IP multicast fundamentals Figure 12: Example 2 PIM and shortest path tree switchover When an IGMP receiver joins a multicast group, PIM on the leaf router first joins the shared tree. After the first packet is received on the shared tree, the router uses the source address information in the packet to immediately switch over to the shortest path tree (SPT). To guarantee a simple, yet high-performance implementation of PIM-SM, the switch does not support a threshold bit rate in relation to SPT switchover.
IP multicast network design that the remote SMLT is up and therefore the remote peer has already forwarded the data. If the forwarding switch goes down, the other switch receives the data directly over its source SMLT link and takes over forwarding to the receivers. After the original switch comes back up, the original switch again receives the data directly over its source SMLT.
IP multicast fundamentals Figure 13: Multicast SMLT triangle Consider an example where one of the peers, vIST-A, is the PIM DR for the source VLAN, and the source data is hashed to vIST-A from the Layer 2 source edge. vIST-A forwards traffic to the receiver edge using the SMLT link from vIST-A to the receiver edge. If the SMLT link fails, vIST-A does not forward traffic over the vIST link to vIST-B, and the receiver edge does receive the data.
IP multicast network design • Do not configure dual redundant RPs. One vIST peer is the RP for a group. • Do not configure one vIST peer as both the DR for the source VLAN and the RP for the receiver group. The system forwards the traffic to the RP or to the DR, depending on which peer receives the source, and, if the SMLT link to the receiver goes down there will be no data loss. PIM-SM and static RP Use static RP to provide security, interoperability, and redundancy for PIM-SM multicast networks.
IP multicast fundamentals Figure 14: RP failover with default unicast routes Because failover is determined by unicast routing behavior, carefully consider the unicast routing design, as well as the IP address you select for the RP. Static RP failover performance depends on the convergence time of the unicast routing protocol. For quick convergence, Avaya recommends that you use a link state protocol, such as OSPF.
IP multicast network design Figure 15: Unsupported static RP configuration Switches 10, 15, and 16 use static RP, whereas switch 2 uses dynamic RP. The source is at switch 10, and the receivers are switches 15 and 16. The RP is at switch 15 locally. The receiver on switch 16 cannot receive packets because its SPT goes through switch 2. Switch 2 is in a dynamic RP domain, so it cannot learn about the RP on switch 15. However, (S, G) records are created and deleted on switch 16 every 210 seconds.
IP multicast fundamentals PIM-SM design and the BSR hash algorithm To optimize the flow of traffic down the shared trees in a network that uses a BSR to dynamically advertise candidate RPs, consider the hash function. The BSR uses the hash function to assign multicast group addresses to each C-RP. The BSR distributes the hash mask used to compute the RP assignment. For example, if two RPs are candidates for the range 239.0.0.0 through 239.0.0.127, and the hash mask is 255.255.255.
IP multicast network design The hash algorithm works as follows: 1. For each C-RP router with matching group address ranges, a hash value is calculated according to the formula: Hash value [G, M, C(i)] = {1 103 515 245 * [(1 103 515245 * (G&M) +12 345) XOR C(i)] + 12 345} mod 2^31 The hash value is a function of the group address (G), the hash mask (M), and the IP address of the C-RP C(i).
IP multicast fundamentals Figure 17: Receivers on interconnected VLANs IGMP reports that the messages that the receiver sends are forwarded to the DR, and both A and B create (*,G) records. Switch A receives duplicate data through the path from C to A, and through the second path from C to B to A. Switch A discards the data on the second path (assuming the upstream source is A to C). To avoid this waste of resources, Avaya recommends that you do not place receivers on V1.
IP multicast network design If the shortest path from C to the source is through switch B, and the interface between C and B does not have PIM-SM enabled, then C cannot switch to the SPT. C discards data that comes through the shared path tree (that is, through A). The simple workaround is to enable PIM on VLAN1 between C and B.
IP multicast fundamentals Protocol Independent Multicast-Source Specific Multicast guidelines PIM-Source Specific Multicast (SSM) is a one-to-many model that uses a subset of the PIM-SM features. In this model, members of an SSM group can only receive multicast traffic from a specific source or sources, which is more efficient and puts less load on multicast routing devices. IGMPv3 supports PIM-SSM by enabling a host to selectively request traffic from individual sources within a multicast group.
IP multicast network design join a TV channel and IGMP leaves to exit the channel. After a viewer changes channels, an IGMPv2 leave for the old channel (multicast group) is issued, and a membership report for the new channel is sent. If viewers change channels continuously, the number of joins and leaves can become large, particularly if many viewers attach to the switch. VSP 4000 supports more than a thousand joins and leaves per second, which is well adapted to TV applications.
IP multicast fundamentals propagation across the network if users change channels rapidly. Leave latency also depends on the robustness value, so a value of 2 equates to a leave latency of twice the LMQI. Determine the proper LMQI value for your particular network through testing. If a very large number of users connect to a port, assigning a value of 3 can lead to a storm of report messages after a group-specific query is sent.
Protocol Independent Multicast over IPv6 PIM-SM over IPv6 features The following are features of PIM-SM over IPv6: • Compliant with RFC 4601 • Multicast networks built by PIM IPv4 and PIM IPv6 do not overlap • IPv4 receiver hosts cannot receive data from IPv6 source hosts and vice versa • IPv4 and IPv6 multicast protocols can be enabled at the same time on the same VLAN • PIM IPv4 and PIM IPv6 can be configured on the same VLAN • PIM IPv4 and PIM IPv6 must be configured separately • Supports sparse and ssm
IP multicast fundamentals - IP mroute stream limit - Bidirectional PIM - Multicast Border Router (PMBR) - VRF support for PIM (GRT only) - IGMP and PIM mtrace capability - High Availability (HA) IPv6 interface multiple addresses IPv6 interfaces can have multiple addresses associated with them. A router running PIM for IPv6 has a network unique domain-wide reachable IPv6 VLAN address used for multiple hop messages. A link local address is associated with the VLAN.
Chapter 4: IP multicast basic configuration using ACLI To provide multicasting services, you need a host membership protocol. Hosts subscribe to multicast services using a host membership protocol. The Internet Group Management Protocol (IGMP) is an example of a host membership protocol. A multicast routing protocol optimizes the routing of multicast information to avoid loops and restrict multicast traffic to networks that use host membership.
IP multicast basic configuration using ACLI enable configure terminal 2. Disable the boot flag: no boot config flags spbm-config-mode The system responds with these messages: Warning: Please save the configuration and reboot the switch for this to take effect. Warning: Please carefully save your configuration file before rebooting the switch. Saving configuration file when spbm-configmode is changed to disable, removes SPBM configurations from the configuration file. 3.

Chapter 6: Multicast Listener Discovery fundamentals This chapter provides an overview of Multicast Listener Discovery (MLD) snooping for IPv6 multicast traffic. MLD MLD is an asymmetric protocol. It specifies separate behaviors for multicast address listeners (that is, hosts or routers that listen to multicast packets) and multicast routers. Each multicast router learns, for each directly attached link, which multicast addresses and which sources have listeners on that link.
MLD Querier MLD Querier MLD Querier is similar to IGMP querier. A multicast query router communicates with hosts on a local network by sending MLD queries. This router periodically sends a general query message to each local network of the router. This is standard multicast behavior. Note: Queries are sent only if PIM is enabled globally and on the interface. PIM and snooping cannot be enabled at the same time. Each VLAN using MLD multicast must have a router performing multicast queries.
Multicast Listener Discovery fundamentals figure, when MLD snooping is enabled and IPv6 multicast packets are transmitted, only the interested hosts receive the IP multicast packets. Figure 19: IPv6 multicast packet transmission when MLD snooping is enabled and not enabled The following figure shows IPv6 multicast packets transmitted when MLD v2 snooping is enabled and not enabled.
