CONFIGURING THE SWITCH

•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)#interface vlan 1		4-119
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
DVMRP is enabled
Metric is 2
