Displaying Multicast Route Data
The commands in this section display multicast routing information on pack
ets sent from multicast sources to IP multicast groups detected by the routing
switch.
Listing Basic Route Data for Active Multicast Groups
Syntax: show ip mroute
Lists the following data for all VLANs actively forwarding
routed, multicast traffic.
Group Address: The multicast address of the specific multicast
group (flow).
Source Address: The IP address of the multicast group source.
Neighbor: The IP address of the upstream multicast router
interface (VLAN) from which the multicast traffic is coming.
A blank field for a given multicast group indicates that the
multicast server is directly connected to the router.
VLAN: The interface on which the multicast traffic is moving.
For example, the next figure displays the
show ip mroute output illustrating a
case where two multicast groups are from the same multicast server source.
ProCurve(config)# show ip mroute
