Monitoring RP Routers and the RP Mapping Agent in a PIM Sparse Mode Environment for IPv4

Purpose

Display information about RP routers and the RP mapping agent in a PIM sparse mode environment.

Action

To display information about RP routers and the RP mapping agent in a PIM sparse mode environment.

To display information on a PIM router that is an Auto RP mapping agent:

host1:1#show ip pim auto-rp 
This PIM router is an Auto RP mapping agent.
  Configured with ttl 64
  [ Using interface addr 121.0.0.1, interval 60 ].
PIM AutoRP candidate RP mapping(s)

To display information on a PIM router that is not an Auto RP mapping agent:

host1:1# show ip pim auto-rp
This PIM router is _not_ an Auto RP mapping agent.
PIM AutoRP candidate RP mapping(s)
Candidate RP 122.0.0.1
  Group(s) 224.0.0.0/4, AutoRP, ttl 64, interval 60, from access List 1
Candidate RP 122.0.0.1
  Group(s) 224.0.1.39/32 (negative), AutoRP, ttl 64, interval 60, from access List 1
Candidate RP 122.0.0.1
  Group(s) 224.0.1.40/32 (negative), AutoRP, ttl 64, interval 60, from access List 1

Field Description

Configured with ttl

Number of hops for which the RP discovery message is valid

Using interface addr

interval
