Limiting the Source-Active Messages from a Peer

To limit the source-active messages from a peer, use the following commands.

OPTIONAL: Store sources that are received after the limit is reached in the rejected SA cache.

CONFIGURATION mode

ip msdp cache-rejected-sa

Set the upper limit for the number of sources allowed from an MSDP peer.

CONFIGURATION mode

ip msdp peer peer-address sa-limit

The default limit is 100K.

If the total number of sources received from the peer is already larger than the limit when this

configuration is applied, those sources are not discarded. To enforce the limit in such a situation, first

clear the SA cache.

You can prevent MSDP from caching an active source based on source and/or group. Because the

source is not cached, it is not advertised to remote RPs.

OPTIONAL: Cache sources that are denied by the redistribute list in the rejected SA cache.

CONFIGURATION mode

ip msdp cache-rejected-sa

Prevent the system from caching local SA entries based on source and group using an extended ACL.

CONFIGURATION mode

ip msdp redistribute list

Multicast Source Discovery Protocol (MSDP)
