Enable IPv6 on each interface on which you plan to enable OSPFv3. You enable IPv6 on an interface by configuring an IP address or explicitly enabling IPv6 on that interface.
-
Enter the
configure terminal command to access global configuration mode.
device# configure terminal
-
Enter the
ip router-id command to specify the router ID.
device(config) ip router-id 10.11.12.13
-
Enter the
ipv6 router ospf command to enter OSPFv3 router configuration mode and enable OSPFv3 on the device.
device(config)# ipv6 router ospf
-
Enter the
area command to define an OSPFv3 area ID.
device(config-ipv6-router-ospf-vrf-default-vrf)# area 0
-
Enter the
area command to define a second OSPFv3 area ID.
device(config-ipv6-router-ospf-vrf-default-vrf)# area 10.1.1.1
The following example assigns an OSPFv3 ID to two areas. One of the areas is assigned by decimal number. The second area is assigned by IP address.
device# configure terminal
device(config)# ip router-id 10.11.12.13
device(config)# ipv6 router ospf
device(config-ipv6-router-ospf-vrf-default-vrf)# area 0
device(config-ipv6-router-ospf-vrf-default-vrf)# area 10.1.1.1
