ULTICAST
Modifies the metric or "cost" of an existing DVMRP tunnel configuration
on a Multilayer Switching Module.
Valid Minimum Configuration
ip m d t m
Important Consideration
When you first define a tunnel, the module automatically assigns the
value 1 as the metric or "cost" of the tunnel (which is different from
the interface metric). Use this command to modify the metric value on
any existing tunnel configuration.
The cost affects the shape of the IP multicast spanning tree when
there are multiple paths to the same downstream destination. The
routing protocol (DVMRP) selects the lower cost path first.
