Review the exhibit.

A service provider wants to connect the sites for two customers (indicated in red and green in the exhibit). The two customers are using the same IP ranges 192.168.0.0/16.

Referring to the exhibit, what should the service provider do to accomplish this task?

Show Suggested Answer Hide Answer
Suggested Answer: A

Referring to the exhibit, the service provider should implement L3VPN using the MP-BGP protocol to connect the sites for two customers (indicated in red and green in the exhibit). L3VPN is a type of VPN that uses MPLS to provide IP connectivity between customer sites across a service provider network. L3VPN allows customers to use overlapping or identical IP addresses without causing conflicts or requiring NAT. L3VPN uses MP-BGP to exchange VPN routes between PE routers, which are routers that connect customer networks to the service provider network. MP-BGP is an extension of BGP that can carry multiple address families, such as VPNv4 or VPNv6, along with additional attributes, such as route distinguisher (RD) and route target (RT).RD is used to make customer routes unique within the service provider network, while RT is used to control which routes are imported or exported between different VPNs3.

Using unique AS numbers sounds familiar, but I thought that was more about routing policies than solving the IP overlap issue. I'm leaning towards option A.

I practiced a similar question about OSPF instances, but I can't recall if it really applies here. Option C might not be the best fit.

I'm not entirely sure, but I think connecting each customer to dedicated PEs could help isolate their traffic. Maybe option B?

I remember studying about L3VPNs and how they can help with overlapping IP addresses, so option A seems like a good choice.

I'm pretty confident this is an L3VPN question. Option A seems like the right approach to me, but I'll double-check the details.

I'm a bit confused by the IP range overlap. Does that mean we need to use some kind of VPN solution? I'm not sure which option is best.

Okay, I think I've got this. The key is to isolate the two customers' networks, so I'm leaning towards option B.

The OSPF instance for each customer in option C seems interesting, but I'm not sure if that's the most efficient solution here. I'll have to weigh the pros and cons.

I've seen questions like this before, and the key is to pay attention to the specific wording of each statement. Some of these might seem similar, but there are likely subtle differences that will determine which ones are true.
