Multicast and Routing Guide K/KA/KB.15.15

Example 44 Route entry data for a specific multicast group
The neighbor field indicates that the router is receiving multicast traffic from a neighboring PIM
router. A blank neighbor field indicates that the multicast source is directly connected to the router
instead of another PIM router.
HP Switch(config)# show ip mroute 239.255.12.42 10.0.0.10

Example 45 Showing route entry data for a registered, non-forwarding flow
Blank neighbor and unicast routing protocol fields indicate the special registered, non-forwarding
RP condition.

Listing all VLANs having currently active PIM flows
Syntax:
show ip mroute interface [vid]
This command displays exactly the same output as the command show ip pim
interface vid (See “Listing currently configured PIM interfaces” (page 85).)
Viewing PIM-specific data
The commands in this section display PIM-specific multicast routing information for IP multicast
groups detected by the router.
