The route-policy for anycast RP is as defined below.
route-policy anycast-policy
if destination in group-set then
pass
endif
end-policy
!
The group-set command is a XR prefix-set configuration, an example is as shown below:
prefix-set group-set
227.1.1.1/32
end-set
An alternate way of performing this procedure is using export-rt and import-rt configuration commands.
Here, the router announcing the Type-5 route must have the export-rt configured, and the router learning
the source must have the import-rt configured.

Receiver-only VRFs Supports receiver-only VRFs. In receiver-only VRFs, the I-PMSI or the MS-PMSI
routes do not carry any tunnel information. This reduces the state on the P routers.
The configuration is as shown below:
