The traditional approach to OSPFv3 configuration involves creating an OSPF routing process, going into the interfaces that you want to participate in the OSPF process, and instructing those interfaces to be part of that process.
The steps required to configure OSPFv3 using the traditional approach are as follows:
Step 1: Enable IPv6 unicast routing on the router (if it is not already enabled). This can be accomplished with the
ipv6 unicast-routing global configuration mode command. Although not required, a best practice is to also enable Cisco Express Forwarding (CEF) for IPv6, using the
ipv6 cef command, because CEF enables the router to make more efficient route lookups.
Step 2: Start the OSPF process with the
ipv6 router ospf <process-id> command, issued in global configuration mode.
Step 3: (Optional) Configure a router ID for the OSPF process with the
router-id <rid> command, where the
rid is a 32-bit value, in router configuration mode. This router ID is commonly an IPv4 address of one of the router’s interfaces. If you do not statically configure a router ID, the router attempts to dynamically determine a router ID to use based on currently active IPv4 addresses on the router. However, if you do not set a router ID, and no active IPv4 addresses exist on the router, the OSPF process will fail to start.
Step 4: Instruct one or more interfaces to participate in the OSPF routing process by entering the
ipv6 ospf <process-id> area <area_number> command in interface configuration mode.
Here's a nice
link comparing OSPFv2 and OSPFv3 routing protocol.
