Topic #: 6
[All JN0-664 Questions]

Exhibit

You are examining an L3VPN route that includes the information shown in the exhibit

Which statement is correct in this scenario?

Show Suggested Answer Hide Answer
Suggested Answer: A

BGP add-path is a feature that allows the advertisement of multiple paths through the same peering session for the same prefix without the new paths implicitly replacing any previous paths. This behavior promotes path diversity and reduces multi-exit discriminator (MED) oscillations. BGP add-path is implemented by adding a path identifier to each path in the NLRI. The path identifier can be considered as something similar to a route distinguisher in VPNs, except that a path ID can apply to any address family.Path IDs are unique to a peering session and are generated for each network3. In this question, we have a route reflector (RR) that receives two routes for the same prefix (192.168.0.0/16) from an EBGP neighbor. By default, the RR will only advertise its best path to its clients (R1 and R2). However, we want R1 and R2 to receive both routes from the RR. To achieve this, we need to configure BGP add-path on the RR and enable it to send multiple paths for the same prefix to its clients.

I thought route targets were different from route distinguishers?

That's definitely a Type 1 route distinguisher.

I’m pretty confident that the exhibit shows a route target, but I need to double-check the definitions to be sure.

I’m leaning towards Type 2 for this one, but I keep mixing up the types. I wish I had reviewed the differences more thoroughly.

This question feels familiar; I practiced one about route distinguishers last week. I think Type 0 is related to something else, but I can't recall exactly what.

I think I remember that Type 1 route distinguishers are used for VPNv4 routes, but I'm not entirely sure if that's what we're looking at here.

I'm a bit confused by this question. Is the active role determined by the physical address or the transport address? I'll need to double-check the LDP protocol specifications to be sure.

Based on the information provided, I think the correct answer is option A: sap 1/1/1:200.100. The top tag of 200 and bottom tag of 100 match what CE-B is expecting.

The exhibit is as clear as mud. I'm just gonna go with my gut and choose option C. If it's wrong, I'll blame the question design!
