8.4.5 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.
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.
