• Question 451:

  You are adding IPv6 to an existing IPv4 network running OSPF. Your plan is to use OSPFv3 to route both IPv4 and IPv6 prefixes. Which configuration will enable OSPFv3 to advertise prefixes for both IPv4 and IPv6?

  A. user@host# show protocols ospf3 realm ipv4-unicast { area 0.0.0.0 { interface ge-0/0/0.0; } } area 0.0.0.0 { interface ge-0/0/0.0; }
  B. user@host# show protocols ospf3 export ipv4; area 0.0.0.0 { interface ge-0/0/0.0; }
  C. user@host# show protocols ospf area 0.0.0.0 { interface ge-0/0/0.0; } user@host# show protocols ospf3 area 0.0.0.0 { interface ge-0/0/0.0; }
  D. user@host# show protocols ospf3 rib-group inet.0; area 0.0.0.0 { interface ge-0/0/0.0; }
  A. user@host# show protocols ospf3 realm ipv4-unicast { area 0.0.0.0 { interface ge-0/0/0.0; } } area 0.0.0.0 { interface ge-0/0/0.0; }
