Example 22 The show ip mroute interface command on routing switch "#2" in Figure 8

(page 44)

HP Switch(config)# show ip mroute interface 29

IP Multicast Interface

VLAN : 29

Protocol : PIM-DM

TTL Threshold : 0

Viewing data for a specified flow (multicast group)

Syntax:

show ip [mroute] [multicast-ip-addr source-ip-addr]

Lists the following data for the specified multicast flow (source-group pair):

[Group Address] The multicast group IP address for the

specified flow.

[Source Address] The source IP address for the specified flow.

[neighbor] Lists the IP address of the upstream next-hop

router running PIM-DM; that is, the router

from which the routing switch is receiving

datagrams for the current multicast group.

This value is 0.0.0.0 if the routing switch has

not detected the upstream next-hop router's

IP address. This field is empty if the multicast

server is directly connected to the routing

switch.

[VLAN] The interface on which the router receives

the multicast flow.

[Up Time (Sec)] The elapsed time in seconds since the routing

switch learned the information for the current

instance of the indicated multicast flow.

NOTE: On an originator router, when a

forwarding flow moves to a non-forwarding

state (i.e. when pruned) the Up Time value

for that flow is reset to 0.

[Expire Time (Sec)] An mroute which is in a forwarding state —

one which represents an active, connected

flow for which there are downstream routers

and/or locally connected hosts interested in

the flow — does not expire. When other

PIM-DM routers or locally connected hosts

are no longer interested in an active flow,

the related mroute on an originator router

moves to a blocking state, and an mroute in

this state does not expire either. In both

cases the mroute is only removed by the

system when it is no longer needed and so

the displayed value for expire time in these

situations is not meaningful.
