43.7.3 DVMRP Configuration Examples

As shown in the following figure, add the Ethernet interfaces of Switch A and Switch B to corresponding VLAN,
and enable DVMRP on each VLAN int erface.
SwitchA SwitchB
Vlan 2
Vlan 1 Vlan 1

The configuration procedure for SwitchA and SwitchB is as follows:
(1) Configure SwitchA:
XGS 3-42000R(config)#ip dvmrp multicast-routing
XGS 3-42000R(config)#interface vlan 1
XGS 3-42000R(config-if-Vlan1)# ip address 10.1.1. 1 255. 255. 255. 0
XGS 3-42000R(config-if-Vlan1)# ip dvmrp enable
(2) Configure SwitchB:
XGS 3-42000R(config)#ip dvmrp multicast-routing
XGS 3-42000R(config)#interface vlan 1
XGS 3-42000R(config-if-Vlan1)# ip address 12.1.1. 2 255. 255. 255. 0
XGS 3-42000R(config-if-Vlan1)# ip dvmrp enable
XGS 3-42000R(config-if-Vlan1)#exit
XGS 3-42000R(config)#interface vlan 2
XGS 3-42000R(config-if-Vlan2)# ip address 20.1.1. 1 255. 255. 255. 0
XGS 3-42000R(config-if-Vlan2)# ip dvmrp
Since DVMRP itself does not rely on Unicast Routing Protocol, it is not necessary to configure Unicast
Routing Prot ocol. This is the difference from PIM-DM and PIM-SM.

43.7.4 DVMRP Troubleshooting

In configuring and using DVMRP Protocol, DVMRP Protocol might not operate normally caused by physical
connection or incorrect configuration. Therefore, the user should pay attention to the following issues:
 Firstly to assure that physical connection is correct;
