Changing the Metric for a Route

The metric for DVMRP is hop count. For example, a route with two hops over a slow serial line is preferable to a route with three hops over a faster optical line.

The router increases the number of DVMRP routes in incoming reports by a default metric of one and in outgoing reports by a default of 0. You can change the metric for an interface to promote or demote the preference for associated routes.

ip dvmrp metric-offset

• Use to adjust the number of hops associated with a route. This action specifies that the route is more efficient or less efficient than an alternative route.
• Use the in keyword to specify the number of hops by which the router increases the number of DVMRP routes advertised in incoming DVMRP reports. This option is the default.
• Use the out keyword to specify the number of hops by which the router increases the number of DVMRP routes advertised in outgoing DVMRP reports.
• Example

  host1:boston(config-if)#ip dvmrp metric-offset in 3

• Use the no version to revert to the default settings: 1 for incoming reports and 0 for outgoing reports.
• See ip dvmrp metric-offset.
