7.8 Troubleshooting MSDP
7.8.1 MSDP Peers Stay in Down State
I. Symptom
The configured MSDP peers stay in the down state.
II. Analysis
z
A TCP connection–based MSDP peering relationship is established between the
local interface address and the MSDP peer after the configuration.
z
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.
z
If no route is available between the MSDP peers, the TCP connection setup will
also fail.
III. Solution
1) 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.
2) Check that a unicast route is available between the two routers that will become
MSDP peers to each other.
3) 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.
7.8.2 No SA Entries in the Router’s SA Cache
I. Symptom
MSDP fails to send (S, G) entries through SA messages.
II. Analysis
z
The
import-source
command is used to control sending (S, G) entries through SA
messages to MSDP peers. If this command is executed without the
acl-number
