• Status – Enables or disables DVMRP.
- If DVMRP is enabled on any interface, Layer 3 IGMP should also be
enabled on the router (page 3-144).
- If DVMRP is disabled, the interface cannot propagate IP multicast
routing information. However, as long as IGMP snooping is enabled,
the interface will still forward multicast traffic to downstream group
members within the VLAN. But if IGMP snooping is disabled, then
the interface will flood incoming multicast traffic to all ports in the
attached VLAN.
Web – Click Routing Protocol, DVMRP, Interface Settings. Select a VLAN
from the drop-down box under DVMRP Interface Settings, modify the
Metric if required, set the Status to Enabled or Disabled, and click Apply.
CLI – This example enables DVMRP and sets the metric for VLAN 1.

Console(config-if)#ip dvmrp 4-296
Console(config-if)#ip dvmrp metric 2 4-297
Console(config-if)#end
Console#show ip dvmrp interface 4-301
Vlan 1 is up
