Configuration Example
This example shows a partial configuration of Router A and Router C in
more than one customer (like the customer in
case, they might have similar configurations. That is, they accept SAs only from a default peer if the SA is permitted by
the corresponding prefix list.
Router A
Router(config)# ip msdp default-peer 10.1.1.1
Router(config)# ip msdp default-peer 10.1.1.1 prefix-list site-a
Router(config)# ip prefix-list site-b permit 10.0.0.0/1
Router C
Router(config)# ip msdp default-peer 10.1.1.1 prefix-list site-a
Router(config)# ip prefix-list site-b permit 10.0.0.0/1
This example shows how to enable the cache state for all sources in 171.69.0.0/16 sending to groups 224.2.0.0/16:
Switch(config)# ip msdp cache-sa-state 100
Switch(config)# access-list 100 permit ip 171.69.0.0 0.0.255.255 224.2.0.0 0.0.255.255
Purpose
Debugs an MSDP activity.
Debugs MSDP peer reset reasons.
Displays the number of sources and groups
originated in SA messages from each autonomous
system. The ip msdp cache-sa-state command
must be configured for this command to produce any
output.
Displays detailed information about an MSDP peer.
Displays (S,G) state learned from MSDP peers.
Displays MSDP peer status and SA message counts.
Purpose
Clears the TCP connection to the specified MSDP peer,
resetting all MSDP message counters.
Clears statistics counters for one or all the MSDP peers
without resetting the sessions.
Clears the SA cache entries for all entries, all sources for a
specific group, or all entries for a specific source/group pair.
