2) Further check that a unicast route exists between two routers that will become
MSDP peers and that the route leads to the two peers.
3) Check that the interface addresses of the MSDP peers are consistent. Use the
display current-configuration
command to check that the address of the local
connect-interface interface is consistent with the address of the corresponding
MSDP peer.
8.7.2 No SA Entry in the SA Cache of the Router
I. Symptom
An MSDP fails to send (S, G) forwarding entries via an SA message.
II. Analysis
You can use the
import-source
command to send the (S, G) entries of the local
multicast domain to the neighboring MSDP peer via SA messages. The
acl
keyword is
optional. If you do not use this keyword, all (S, G) entries will be filtered out by default,
that is, none of the (S, G) entries in the local multicast domain will be advertised. Before
the
import-source
command is carried out, the system will send all (S, G) entries in the
local multicast domain. If the MSDP fails to send the (S, G) entries of the local multicast
domain via SA messages, verify that the
import-source
command is configured
correctly.
III. Solution
1) Check the connectivity of the route between the routers. Use the
display ip
routing-table
command to check that the unicast route between the routers are
correct.
2) Further check that a unicast route exists between two routers that will become
MSDP peers and that the route leads to the two peers.
3) Verify the configuration of the
import-source
command and the corresponding
ACL to ensure that the ACL rule filters the right (S, G) entries.
