Configuring DVMRP
The following example configures two DVMRP interfaces on the switch to
enable inter-VLAN multicast routing.
To configure the switch:
1
Globally enable IP routing and IP multicast.
console#configure
console(config)#ip routing
console(config)#ip multicast-routing
2
Globally enable DVMRP and IGMP so that this L3 switch can manage
group membership information for its directly-connected hosts. Enabling
IGMP is not required if there are no directly-connected hosts; however, it is
recommended that it be enabled to ensure correct operation of multicast
routing.
console(config)#ip dvmrp
3
Enable DVMRP and IGMP on VLAN routing interfaces 10 and 20.
console(config)#interface vlan 10
console(config-if-vlan10)#ip address 192.168.10.1 255.255.255.0
console(config-if-vlan10)#ip dvmrp
console(config-if-vlan10)#exit
console(config)#interface vlan 20
console(config-if-vlan20)#ip address 192.168.20.1 255.255.255.0
console(config-if-vlan20)#ip dvmrp
console(config-if-vlan20)#exit
