OSPFv3 address-family

This is possible to run the two address-families under the same OSPF process since Cisco IOS Software Release 15.1(3)S. You can do this as : R9(config)# ipv6 unicast-routing R9(config)# ipv6 cef Then : R9(config)# router ospfv3 1 R9(config-router)#address-family ipv4 unicast R9(config-router-af)#router-id
