Configuring OSPF and OSPFv3 1187
Interconnecting an IPv4 Backbone and Local IPv6 Network
In Figure35-38, two Dell Networking 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 35-38. IPv4 and IPv6 Interconnection Example
To configure Switch A:
1
Create the VLANs.
console(config)#vlan 2,15
console(config-vlan70,80,90)#interface te1/0/1
console(config-if-Te1/0/1)#switchport mode trunk
console(config-if-Te1/0/1)#interface gi1/0/1
console(config-if-Gi1/0/1)#switchport access vlan 2
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
