MSDP peers stay in disabled state
Symptom
The configured MSDP peers stay in disabled state.
Analysis
Possible reasons for the problem might include the following:
•
A TCP connection-based MSDP peering relationship is established between the local interface
address and the MSDP peer.
•
The TCP connection setup fails if the local interface address is not consistent with the MSDP
peer address configured on the peer router.
•
If no route is available between the MSDP peers, the TCP connection setup fails.
Solution
To resolve the problem:
1.
Use the
display ip routing-table
command to verify that the unicast route between the routers
is reachable.
2.
Verify that a unicast route is available between the two routers that will become MSDP peers to
each other.
3.
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.
4.
If the problem persists, contact Hewlett Packard Enterprise Support.
No SA entries exist in the router's SA message cache
Symptom
MSDP fails to send (S, G) entries through SA messages.
Analysis
Possible reasons for the problem might include the following:
•
The
import-source
command controls sending (S, G) entries through SA messages to MSDP
peers. If this command is executed without the
ipv4-acl-number
argument, all the (S, G) entries
are filtered out, and no (S, G) entries of the local domain are advertised.
•
If you do not use the
import-source
command, the system advertises all the (S, G) entries of
the local domain. If MSDP fails to send (S, G) entries through SA messages, verify that the
import-source
command has been correctly configured.
Solution
To resolve the problem:
1.
Use the
display ip routing-table
command to verify that the unicast route between the routers
is reachable.
2.
Verify that a unicast route is available between the two routers that will become MSDP peers to
each other.
3.
Verify the configuration of the
import-source
command and its
ipv4-acl-number
argument, and
make sure the ACL rule filters appropriate (S, G) entries.
