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. Use undo bestroute compare-med to disable this comparison.
