Explanation

The first step to configure OSPFv3 under IPv6 is to enable IPv6 unicast routing: R1(config)# ipv6 unicast-routing Also we need to enable the OSPF process: R1(config)# ipv6 router ospf 1 There are a few changes in configuring OSPFv3 vs OSPF for IPv4. Instead of using the "network" and "area" commands in ospf router configuration mode you now configure OSPFv3 on a per interface basis using the ipv6 ospf area command in interface configuration mode. For example: R1(config)# interface fa0/0 R1(config-if)# ipv6 ospf 1 area 0 Note: The "network" command does not exist in OSPFv3. You will see under the section how to implement ospf for ipv6 it only has 1 REQUIRED thing configure interface and in the comments it says that OSPF IPV6 routing is disabled by default.
