Fields in the IP Multicast DVMRP Interface Detail Display
Field Description
Index Number associated with the interface for identification
purposes
Address IP address of the interface
Metric Numeric DVMRP metric or “cost” that you assign to the
interface
State Role that the interface plays in IP multicast delivery. One
or more of the following descriptors may appear:
■ querier — The interface is functioning as the IGMP
Querier for its subnetwork.
■ non-querier — The interface is not functioning as
the IGMP Querier for its subnetwork.
■ leaf — There are no routers downstream of this
interface; IP multicast group members may reside on
this subnetwork.
■ non-leaf — The interface is a branch in the IP
multicast delivery tree. There are one or more IP
multicast routing interfaces downstream of this
interface.
■ one-way — Traffic is moving downstream only.
■ disabled — DVMRP is disabled on the interface.
■ up — The IP interface is available to support network
communication.
■ down — The IP interface is not available to support
network communication.
Group IP multicast group addresses of the traffic that is being
received and forwarded on that interface.
Peer, Port IP address of the upstream router. The additional
information to the right relates to the version of DVMRP
that is running and the port in the local interface that
connects to the peer router.
