Displaying and Debugging MSDP Configuration

Configuring SA Message
Cache
With the SA message caching mechanism enabled on the router, the group that a
new member subsequently joins can obtain all active sources directly from the SA
cache and join the corresponding SPT source tree, instead of waiting for the next
SA message.
You can configure the number of SA entries cached in each MSDP peer on the
router by executing the following command, but the number must be within the
system limit. The maximum number of cached SA messages on each MSDP peer
and on all the MSDP peers on a router is limited by the system. To protect a router
against Deny of Service (DoS) attacks, you can manually configure the maximum
number of SA messages cached on the router. Generally, the configured number
of SA messages cached should be less than the system limit.
