Question Image

You have configured IPv4 and IPv6 in the network, and every OSPF neighbor relationship is established. You apply the configuration shown in the exhibit.

Which statement is true in this scenario?

  • A There will not be a route in R1 for network 172.16.2.0/24.
  • B There will only be an OSPFv3 entry in R1 for network 172.16.2.0/24.
  • C There will only be an OSPFv2 entry in R1 for network 172.16.2.0/24.
  • D There will be an OSPFv2 and OSPFv3 entry in R1 for network 172.16.2.0/24.
Explanation

An OSPFv3 ipv4-unicast realm enables OSPFv3 to advertise IPv4 unicast routes and maps them to the IPv4 routing table. Because the same interfaces are also enabled under OSPFv2, the IPv4 prefix 172.16.2.0/24 is learned on R1 through both OSPFv2 and the OSPFv3 IPv4-unicast realm.
