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
