Troubleshooting MSDP

The configured MSDP peers stay in the down state.

A TCP connection–based MSDP peering relationship is established between the local interface

address and the MSDP peer after the configuration.

The TCP connection setup will fail if there is a consistency between the local interface address and

the MSDP peer address configured on the router.

If no route is available between the MSDP peers, the TCP connection setup will also fail.

Check that a route is available between the routers. Carry out the display ip routing-table

command to check whether the unicast route between the routers is correct.

Check that a unicast route is available between the two routers that will become MSDP peers to

Verify the interface address consistency between the MSDP peers. Use the display

current-configuration command to verify that the local interface address and the MSDP peer

address of the remote router are the same.
