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.
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.
You can import routing information from other protocols into the DVMRP routing table.
Only routes that appear in the RPF table can be imported. To do so:
If you want to use IS-IS, OSPF, or RIP routes, make those routes available to multicast

protocols. See "Defining Static Routes for Reverse-Path Forwarding" on page 7.
Access Router Configuration mode.
2.
Specify a route map.
3.
Import information from one type of routing domain into another.
4.
Use to import information from another type of routing domain to the DVMRP domain.
DVMRP can import only routes that appear in the RPF table.
Specify the source protocol from which routes are being redistributed. It can be one of
the following keywords: bgp, isis, ospf, static, or connected.
Use the static keyword to redistribute static IP multicast routes into DVMRP.
