When using OSPFv3 for an IPv4 environment, which statement is correct?

Show Suggested Answer Hide Answer
Suggested Answer: A, B

To provide Internet access for the hosts at Site 1, you need to configure static routes in the main routing instance on PE-1 that point to the VPN-A.inet.0 table as the next hop. This allows PE-1 to forward traffic from the Internet to CE-1 using MPLS labels and vice versa. You need to configure two static routes: one for the 10.1.2.0/24 prefix that represents the private network of Site 1, and one for the 203.0.113.1/32 prefix that represents the public IP address of CE-1.

Yeah, it’s confusing how OSPFv3 is named.

I vaguely recall something about OSPFv3 needing specific configurations for IPv4 support, but I can't remember the details. Option D sounds familiar, but I'm not confident.

I’m a bit confused about OSPFv3 and its compatibility with IPv4. I feel like I read that it’s not backward compatible, which might point to option C.

I think I saw a practice question that mentioned OSPFv3 can handle both IPv4 and IPv6, but not together. That makes me think option B could be correct.

I remember studying that OSPFv3 is primarily designed for IPv6, so I'm leaning towards option C, but I'm not entirely sure.

I'm not entirely sure about this one. I know OSPFv3 is for IPv6, but the question is about an IPv4 environment. I'll have to review the material on OSPFv3 and IPv4 support before I can confidently answer this.

I'm leaning towards D. The question specifically mentions "when using OSPFv3 for an IPv4 environment," so I think the answer is that OSPFv3 supports IPv4 only on interfaces with family inet6 defined.

Okay, let me break this down. OSPFv3 is the IPv6 version, so it makes sense that it wouldn't support IPv4 in the same routing instance. I'm going to go with B.

Hmm, I'm a bit confused on this one. I know OSPFv3 is the IPv6 version of OSPF, but I'm not sure how it handles IPv4. I'll have to think this through carefully.

Okay, let's see. An OTDR measures the light reflected back from the fiber, so it should be able to detect physical intrusions or disturbances. I'm leaning towards option A, but I'll double-check the other choices just to be sure.

Option D sounds a bit odd. Why would OSPFv3 only support IPv4 on interfaces with family inet6 defined? Seems like a strange requirement.
