1404 CHAPTER 90: PIM CONFIGURATION COMMANDS
group-address: Address of the multicast group of which the RP information is to
be displayed, in the range of 224.0.1.0 to 239.255.255.255. If you do not provide
a group address, this command will display the RP information corresponding to
all multicast groups.
Description Use the
display pim rp-info command to view the RP information.
Note that:
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.
Example # View the RP information corresponding to the multicast group 224.0.1.1 in the
public instance.

# View the RP information corresponding to all multicast groups in the public
instance.
