A. B. C. D.C
By default, OSPFv3 supports unicast IPv6 routes, but you can configure OSPFv3 to support multiple address families. To support an address family other than unicast IPv6, you configure a realm that allows OSPFv3 to advertise IPv4 unicast, IPv4 multicast, or IPv6 multicast routes.
Example of a configuration which support both Ipv4 and Ipv6 prefixes: user@host# show protocols ospf3 realm ipv4-unicast { area 0.0.0.0 { interface fe-0/1/0.0;
}
}
area 0.0.0.0 {
interface fe-0/1/0.0;
}
http://www.juniper.net/documentation/en_US/junos15.1/topics/topic-map/ospfv3-multiple-address-families.htmlThe configuration shown in the exhibit is for the OSPFv3 (Open Shortest Path First version 3) protocol. OSPFv3 is used for routing IPv6 traffic.
The configuration specifies an OSPFv3 area with the identifier 28.32.69.49. The "interface all" statement indicates that all interfaces on the router are included in this OSPFv3 area.
Therefore, option C is the correct answer. The configuration supports IPv6 unicast routes.
Option A and D are incorrect because OSPFv3 is not used for IPv4 traffic or IPv4/IPv6 multicast traffic.
Option B is also incorrect because although OSPFv3 can be used for IPv4 traffic, the configuration shown in the exhibit does not include any specific statements related to IPv4.
