No Exchange Of Locally Registered (S, G) Entries Between Rps - HPE FlexNetwork 5510 HI Series Configuration Manual

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:
Use the display ip routing-table command to verify that the unicast route between the routers
1.
is reachable.
Verify that a unicast route is available between the two routers that will establish an MSDP
2.
peering relationship.
Verify the configuration of the originating-rp command. In the Anycast RP application
3.
environment, use the originating-rp command to configure the RP address in the SA
messages, which must be the local interface address.
Verify that the C-BSR address is different from the Anycast RP address.
