Usage Scenario
If the SA cache function is enabled, the display msdp sa-cache command can be used to display the information about (S, G) entries learned from other MSDP peers in the SA cache. The information includes the source address, group address, address of the source's RP, routing protocol, AS number, and timeout period of entries.
Precautions
This command displays (S, G) entries in the SA cache only when SA cache is enabled (default setting).
# Display (S, G) entries in the SA cache.
