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

AOSPFv3 only supports IPv4.

BOSPFv3 supports both IPv6 and IPv4, but not in the same routing instance.

COSPFv3 is not backward compatible with IPv4

DOSPFv3 supports IPv4 only on interfaces with family inet6 defined

Show Suggested 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.

I bet the exam writer had a good laugh coming up with these options. They really tried to trip us up with that one about IPv4 only on inet6 interfaces!

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

User1: Option D is correct because OSPFv3 uses IPv6 address format for its routing updates.

Wait, so OSPFv3 is not backward compatible with IPv4? That's news to me. I'll have to double-check the documentation on that one.

Hah, imagine if OSPFv3 only supported IPv4. That would be like using a rotary phone to access the internet!
