The default active source limit is 500K messages.

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.
