OSPF and OSPFv3 1329
Interconnecting an IPv4 Backbone and Local IPv6 Network
In Figure 34-38, two Dell EMC 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 34-38. 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
