Configuring OSPF and OSPFv3

Interconnecting an IPv4 Backbone and Local IPv6 Network

In Figure 34-38, two PowerConnect L3 switches are connected as shown in

the diagram. The VLAN 15 routing interface on both switches connects to an

IPv4 backbone network where OSPF is used as the dynamic routing protocol

to exchange IPv4 routes. OSPF allows device 1 and device 2 to learn routes to

each other (from the 20.20.20.x network to the 10.10.10.x network and vice

versa). The VLAN 2 routing interface on both devices connects to the local

IPv6 network. OSPFv3 is used to exchange IPv6 routes between the two

devices. The tunnel interface allows data to be transported between the two

remote IPv6 networks over the IPv4 network.

Figure 34-38. IPv4 and IPv6 Interconnection Example

To configure Switch A:

1 Create the VLANs.

console(config)#vlan 2,15

2 Enable IPv4 and IPv6 routing on the switch.

console(config)#ip routing

console(config)#ipv6 unicast-routing

3 Set the OSPF router ID.

console(config)#router ospf

console(config-router)#router-id 1.1.1.1

console(config-router)#exit

4 Set the OSPFv3 router ID.

console(config)#ipv6 router ospf
