No exchange of locally registered (S, G) entries between RPs
Symptom
RPs fail to exchange their locally registered (S, G) entries with one another in the Anycast RP
application.
Analysis
Possible reasons for the problem might include the following:
•
In the Anycast RP application, RPs in the same PIM-SM domain are configured to be MSDP
peers to achieve redundancy backup among the RPs.
•
An MSDP peer address must be different from the Anycast RP address, and the C-BSR and the
C-RP must be configured on different devices or interfaces.
•
If you configure the
originating-rp
command, MSDP replaces the RP address in the SA
messages with the address of the interface specified in the command.
•
When an MSDP peer receives an SA message, it performs an RPF check on the message. If
the MSDP peer finds that the remote RP address is the local RP address, it discards the SA
message.
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 establish an MSDP
peering relationship.
3.
Verify the configuration of the
originating-rp
command. In the Anycast RP application
environment, use the
originating-rp
command to configure the RP address in the SA
messages, which must be the local interface address.
4.
Verify that the C-BSR address is different from the Anycast RP address.
