No Sa Entry In The Sa Cache Of The Router - Huawei Quidway S3900 Series Operation Manual

Operation Manual – Multicast Protocol
Quidway S3900 Series Ethernet Switches-Release 1510
address of local connect-interface interface is inconsistent with the peer address
configured on the peer router, no TCP connection can be established. If there is no
route between the two peers, no TCP connection can be established.
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) 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.
