Maximum SA Cache Entry Limit

You can configure a limit on the maximum number of SA cache entries that can be stored in the cache database. Once the number of SA cache entries exceeds the pre-configured limit, any newly received cache entries are discarded. You can configure the limit on a per-peer basis. By default, no SA message limit is set. The router can receive an unlimited number of SA entries from an MSDP peer.

Configure a limit on the number of SA entries that can be stored in cache.
configure msdp peer [remoteaddr | all] sa-limit max-sa {vr vr_name}

To allow an unlimited number of SA entries, use 0 (zero) as the value for max-sa.
