Configuring MSDP
We recommend that you do not change the command defaults for the ip msdp keepalive command,
Note
because the command defaults are in accordance with RFC 3618, Multicast Source Discovery Protocol.
If your network environment requires that you modify the defaults, you must configure the same time
values for the keepalive-interval and hold-time-interval arguments on both ends of the MSDP peering
session.
SUMMARY STEPS
1. enable
2. configure terminal
3. ip msdp keepalive {peer-address | peer-name} keepalive-interval hold-time-interval
4. Repeat Step 3 to adjust the keepalive message interval for additional MSDP peers.
5. exit
