Important Considerations
■
Use this command if you want to modify the metric value of 1 that the
system assigns to an interface when you define it, even if DVMRP is
not yet enabled.
■
The metric affects the shape of the IP multicast spanning tree when
there are multiple paths to the same downstream destination. The
lower cost path is the preferred path.
