2 Prevent the system from caching local SA entries based on source and group using an extended ACL.
CONFIGURATION mode
ip msdp redistribute list
Example of Verifying the System is not Caching Local Sources
When you apply this filter, the SA cache is not affected immediately. When sources that are denied by the ACL
time out, they are not refreshed. Until they time out, they continue to reside in the cache. To apply the
redistribute filter to entries already present in the SA cache, first clear the SA cache. You may optionally store
denied sources in the rejected SA cache.
