You are configuring Open Shortest Path First (OSPF) protocol for IPv6 on Router5. The router has two interfaces, which have been configured as follows: S0/0 - 192.168.5.1/24 S0/1 - 10.0.0.6/8 You would like OSPF to route for IPv6 only on the S0/0 network. It should not route for IPv6 on the S0/1 network. The process ID you have chosen to use is 25. You do not want to apply an IPv6 address yet. Which of the following command sets would enable OSPF for IPv6 as required?

A. Router5(config)#ipv6 ospf 25Router5(config)# network 192

B. Router5(config)#ipv6 ospf 25Router5(config)#router-id 192

C. Router5(config)#ipv6 unicast-routing Router5(config)#ipv6 router ospf 25 Router5(config-rtr)#router-id 1
