Description
Use the display pim rp-info command to view the RP information.
Note that:
If neither all-instance nor vpn-instance is specified, this command will display the information on
the public instance.
The RP information includes the information of RPs dynamically found by the BSR mechanism and
static RPs.
Because a non-BSR router refreshes its local RP-Set only based on the received BSR bootstrap
messages, the system does not delete an RP even if its expiry time is 0. Instead, the system waits
for the next bootstrap message from the BSR: if the bootstrap message does not contain
information of the RP, the system will delete it.
