Command Usage
To fully enable DVMRP, you need to enable multicast routing globally for the
router with the ip multicast-routing command (page 4-297), enable DVMRP
globally for the router with the router dvmrp command (page 4-299), and also
enable DVMRP for each interface that will participate in multicast routing with
the ip dvmrp command.
Example
ip dvmrp metric
This command configures the metric used in selecting the reverse path to networks
connected directly to an interface on this router. Use the no form to restore the
default value.
Syntax
ip dvmrp metric interface-metric
no ip dvmrp metric
interface-metric - Metric used to select the best reverse path.
(Range: 1-31)
Default Setting

Command Mode

Command Usage
The DVMRP interface metric is used to choose the best reverse path when
there are multiple paths to the same upstream destination. The lower cost path
is the preferred path.
Example
Console(config)#interface vlan 1
Console(config-if)#ip dvmrp
Console(config-if)#end
Console#show ip dvmrp interface
Vlan 1 is up
DVMRP is enabled
Metric is 1
Console#
Console(config)#interface vlan 1
Console(config-if)#ip dvmrp metric 2
Console(config-if)#
