MSDP Source-Active Cache - 1 entries

Set the upper limit of the number of active sources that the system caches.

The default active source limit is 500K messages. When the total number of active sources reaches the

specified limit, subsequent active sources are dropped even if they pass the reverse path forwarding (RPF) and

policy check.

To limit the number of sources that SA cache stores, use the following command.

Limit the number of sources that can be stored in the SA cache.

EXEC Privilege mode

show ip msdp sa-limit

If the total number of active sources is already larger than the limit when limiting is applied, the sources that

are already in the OS are not discarded. To enforce the limit in such a situation, use the clear ip msdp sa-

cache command to clear all existing entries.

To clear the source-active cache, use the following command.

Clear the SA cache of all, local, or rejected entries, or entries for a specific group.

CONFIGURATION mode

clear ip msdp sa-cache [group-address | local | rejected-sa]
