By default, the router caches the SA state, or rather the (S, G) entry when receiving an
SA message.
Some memory is consumed as the join delay of groups is shortened by this
configuration.

By default, the maximum number of SA caching is 2048.

8.2.7 Requesting Source Information of MSDP Peers

When a new group joins, the router will send a SA request message to the specified
MSDP peer, and the MSDP peer will respond with the SA messages it caches. If the
MSDP peer does not enable the SA caching, the configuration is invalid.
Please perform the following configurations in MSDP view.
