IP multicast routing table


Note: Multicast Routing Table displays of an RP router are different from other routers.

1. The show ip pim sparse-mode mroute command displays the IP multicast routing table. In this table:
RPF nbr

Displays the unicast next-hop to reach RP.

RPF idx

Displays the incoming interface for this (*, G) state.

RP

Displays the IP address for the RP router

The leading dots ....

Stand for VIF index

Router_E# show ip pim sparse-mode mroute

IP Multicast Routing Table

(*,*,RP) Entries: 0

(*,G) Entries: 1

(S,G) Entries: 0

(S,G,rpt) Entries: 0

(*, 224.0.1.3)

RP: 10.10.1.5

RPF nbr: 172.16.1.2

RPF idx: eth-0-2

Upstream State: JOINED

Local ................................

Joined j...............................

Asserted ................................

Outgoing o...............................

At Router_E, eth-0-2 is the incoming interface of the (*, G) entry, and eth-0-1 is on the outgoing
interface list of the (*,G) entry. This means that there is a group member through eth-0-1, and RP
is reachable through eth-0-2.
The 0 position on this 32-bit index is for eth-0-1 (as illustrated in the interface display above).
The j on the 0 index indicates that the Join has come from eth-0-1.

2. Since Router_C is the RP, and the root of this multicast tree, the show ip pim sparse-mode mroute
command on Router_C shows RPF nbr as 0.0.0.0 and RPF idx as none.
