Maintaining MSDP involves deleting MSDP peer statistics and (S, G) information in the SA cache, monitoring MSDP running status, and debugging MSDP for fault locating.
When you delete statistics about MSDP peers, you can choose whether to reset TCP connections between MSDP peers. Resetting TCP connections affects the MSDP running.
You can monitor the MSDP running status by checking brief and detailed information about MSDP peers, (S, G) information in the source active (SA) cache, and the number of (S, G) entries in the SA cache.
