3Com MSR 30, MSR 50 manual Description on the fields of the display pim rp-info command

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-infocommand 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.

<Sysname> display pim rp-info 224.0.1.1 Vpn-instance: public net

BSR RP Address is: 2.2.2.2

Priority: 0

HoldTime: 150

Uptime: 03:01:10

Expires: 00:02:30

RP mapping for this group is: 2.2.2.2

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

<Sysname> display pim rp-info Vpn-instance: public net PIM-SM BSR RP information: Group/MaskLen: 224.0.0.0/4
