IGMPSnooping and Proxy for IPv4, MLD Snooping and Proxy for IPv6, and Querier mode facilitate fast receivers joins and leaves for multicast streams and ensure multi-
cast trafc only reaches interested receivers everywhere in a Layer 2 or a Layer 3 network, including source-specic (SSM) and any-source (ASM) multicast
Multicast VLAN Registration (MVR)uses a dedicated Multicast VLAN to forward multicast streams and avoid duplication for clients in different VLANs
Distance Vector Multicast Routing Protocol (DVMRP)
is a dense mode multicast protocol also called Broad-
cast and Prune Multicasting protocol
• DVMRP uses a distributed routing algorithm to build per-source-group multicast trees
• DVMRP assumes that all hosts are part of a multicast group until it is informed of multicast group changes
• It dynamically generates per-source-group multicast trees using Reverse Path Multicasting
• Trees are calculated and updated dynamically to track membership of individual groups
Multicast routing (PIM-SM and PIM-DM, both IPv4 and
IPv6) ensure multicast streams can reach receivers in
different L3 subnets
• Multicast static routes allowed in Reverse Path Forwarding (RPF) selection
• Multicast dynamic routing (PIM associated with OSPF) including PIM multi-hop RP support for routing around
damage advanced capabilities
• Full support of PIM (S,G,Rpt) state machine events as described in RFC 4601
• Improved Multicast PIM timer accuracy with hardware abstraction layer (HAPI) polling hit status for
multicast entries in real time (without caching)

Layer 3 routing package
Static Routes/ECMP Static Routes for IPv4 and IPv6 • Static and default routes are congurable with next IP address hops to any given destination
• Permitting additional routes creates several options for the network administrator
• The admin can congure multiple next hops to a given destination, intending for the router to load share
across the next hops
• The admin distinguishes static routes by specifying a route preference value: a lower preference value is a
more preferred static route
• A less preferred static route is used if the more preferred static route is unusable (down link, or next hop
cannot be resolved to a MAC address)
• Preference option allows admin to control the preference of individual static routes relative to routes learned
from other sources (such as OSPF) since a static route will be preferred over a dynamic route when routes
from different sources have the same preference
Advanced Static Routing functions for administrative
trafc control
• Static Reject Routes are congurable to control the trafc destined to a particular network so that it is not
forwarded through the router
• Such trafc is discarded and the ICMP destination unreachable message is sent back to the source
• Static reject routes can be typically used to prevent routing loops
• Default routes are congurable as a preference option
In order to facilitate VLAN creation and VLAN routing
using Web GUI, a VLAN Routing Wizard offers
following automated capabilities:
• Create a VLAN and generate a unique name for VLAN
• Add selected ports to the newly created VLAN and remove selected ports from the default VLAN
• Create a LAG, add selected ports to a LAG, then add this LAG to the newly created VLAN
• Enable tagging on selected ports if the port is in another VLAN
• Disable tagging if a selected port does not exist in another VLAN
• Exclude ports that are not selected from the VLAN
• Enable routing on the VLAN using the IP address and subnet mask entered as logical routing interface
DHCP Relay Agents relay DHCP requests from any
routed interface, including VLANs, when DHCP server
doesn’t reside on the same IP network or subnet
• The agent relays requests from a subnet without a DHCP server to a server or next-hop agent on another
subnet
• Unlike a router which switches IP packets transparently, a DHCP relay agent processes DHCP messages and
generates new DHCP messages
• Supports DHCP Relay Option 82 circuit-id and remote-id for VLANs
• Multiple Helper IPs feature allows to congure a DHCP relay agent with multiple DHCP server addresses per
routing interface and to use different server addresses for client packets arriving on different interfaces on the
relay agent server addresses for client packets arriving on different interfaces on the relay agent
