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
Meaning
Table 1 lists the show ip pim auto-rp command output fields.
Table 1: show ip pim auto-rp Output Fields
Field Name | Field Description |
|---|---|
Configured with ttl | Number of hops for which the RP discovery message is valid |
Using interface addr | IP address of the interface from which the router sends RP discovery messages |
interval | Time interval, in seconds, at which the router sends RP discovery messages |
PIM AutoRP candidate RP mapping(s) | Routers that the RP mapping agent is evaluating to determine an RP router for this interface |
