Adding a Metric Offset to the DVMRP Route
The DVMRP metric is the same as a hop-count. The BSR uses increments of 1 to
adjust the metric of a DVMRP route advertised in incoming DVMRP reports by
default. The DVMRP route metric can be changed to assist or sustain a particular
route. The ip dvmrp metric-offset command is used to influence which routes are
used or preferred. It is also associated with the unicast route being reported for each
source network that is reported. The metric is the increment or hop count used to
measure the span between the router originating the report and the source network.
The source network becomes unreachable when it reaches a metric of 32.
Use the following options to add a metric offset to both incoming and outgoing
routing reports:
• Use the ip dvmrp metric-offset in command in Interface Configuration mode to
add an increment to the incoming DVMRP reports, as shown below:
MOT(config-if)#ip dvmrp metric-offset in <n>
where:
n is the increment number from 0 to 31.
• Use the ip dvmrp metric-offset out command in Interface Configuration mode
to add an increment to outgoing DVMRP reports, as shown below:
where:
Note: The default value for in is 1.
