Modifies the metric or “cost” of an existing DVMRP tunnel.

Valid Minimum Configuration

Important Consideration

■When you first define a tunnel, the system 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.
