Field Description Remaining time of the aging timer for the dynamic member port or router port: • In standalone mode, to display the remaining time of a non-aggregate ( 00:01:30 ) port, you must specify the number of the slot where the corresponding card resides by using the slot slot-number option. For an aggregate interface, you do not need to do this.
slot slot-number: Specifies a card by its slot number. If no slot is specified, the command displays information about the hosts tracked by IGMP snooping on the MPU. (In standalone mode.) chassis chassis-number slot slot-number: Specifies a card on a member device. The chassis-number argument specifies an IRF member device ID, and the slot-number argument specifies a card by its slot number.

• display multicast routing-table ip rpf-route-static Use ip rpf-route-static to configure a static multicast route. Use undo ip rpf-route-static to delete a static multicast route from the static multicast routing table.
Usage guidelines The arguments source-address { mask | mask-length }, protocol and policy-name are critical elements in static multicast route configuration. The variation of any of these arguments results in a different configuration. When you configure a static multicast route, the system first examines whether any of these argument exists. If the system finds a match, you must modify the corresponding fields without changing the configuration sequence. Otherwise, the system adds a static multicast route.

The MAC address can be any legal multicast MAC address except 0100-5Exx-xxxx and 3333-xxxx-xxxx, where x represents an arbitrary hexadecimal number from 0 to F. Multicast MAC addresses are the MAC addresses whose the least signification bit of the most significant octet is 1.
Views Any view Default command level 1: Monitor level Parameters source-address: Specifies a multicast source address. group-address: Specifies a multicast group address in the range of 224.0.1.0 to 239.255.255.255. last-hop-router-address: Specifies a last-hop router address, which is the IP address of the local router by default.
Field Description -1 5.5.5.8 (S, G) outgoing interface address of each hop, starting from the last-hop router. Incoming interface address IP address of the interface on which the (S, G) packets arrive. Previous-hop router address IP address of the previous router that forwards the packets to the current route. Input packet count on incoming interface Total number of multicast packets received on the incoming interface.
An interface can act as a forwarding boundary for multiple multicast groups in different address ranges. To achieve this, execute this command on the interface for each multicast address range. Assume that Set A and Set B are multicast forwarding boundary sets with different address ranges, and B is a subset of A. If B is configured after A, A still takes effect. If A is configured after B, B is removed.

Usage guidelines When you use this command, take the following into account: • The size of the forwarding table. In a network that does not support packet fragmentation, if you configure a large queue size, a join/prune message might contain a large number of groups. This might cause the message length to exceed the MTU of the network. As a result, the products that do not support fragmentation drop the join/prune message. • The (S, G) join/prune timeout timer on the upstream device.

MBGP configuration commands For more information about routing policy commands, see Layer 3—IP Routing Command Reference. aggregate (MBGP address family view) Use aggregate to create a summary route in the IPv4 MBGP routing table. Use undo aggregate to remove a summary route.
Keywords Function detail-suppressed Does not suppress the summary route, but it suppresses the advertisement of all the more specific routes. To summarize only some specific routes, use the suppress-policy command. suppress-policy Used to create a summary route and suppress the advertisement of some summarized routes. If you want to suppress some routes selectively and leave other routes still advertised, use the if-match clause of the route-policy command.
Usage guidelines MBGP has no explicit metric for implementing load balancing. Instead, it implements load balancing by using route selection rules. If you do not specify the ibgp or the ebgp keyword, this command configures load sharing for all MBGP routes. You cannot execute the balance number command after you specify the ibgp or the ebgp keyword. To execute the balance number command, use the undo command to remove the previous configuration, and vice versa.
Examples # In IPv4 MBGP address family view, configure BGP to ignore AS_PATH during best route selection. system-view [Sysname] bgp 100 [Sysname-bgp] ipv4-family multicast [Sysname-bgp-af-mul] bestroute as-path-neglect bestroute compare-med (MBGP address family view) Use bestroute compare-med to enable the comparison of the MED for paths from each AS during best route selection.
