Not sure if just configuring the router-id will do it.

I vaguely remember that changing the LDP password isn't usually necessary for peering, so I'm leaning away from option A.

I feel like the answer might be B, but I can't recall if the router ID needs to be set on both R1 and R2 or just R1.

I think we practiced a question similar to this where we had to enable LDP session protection. I wonder if that means we need to configure it on R2 instead of R1.

I remember something about configuring the router ID for LDP, but I'm not sure if it has to be done on both routers or just one.

This seems pretty straightforward. I'll focus on the specific requirements - router-ID for R1 and session protection for R2. I think I can nail this one.

I'm a little confused about the difference between the router-ID and the LDP discovery parameters. I'll need to double-check those in the exam prep material.

Okay, let's see. The key is getting the router-ID set up correctly on R1. And then the session protection on R2. I think I can work through this.

This is a tricky one, but I think B is the right answer. Changing the password or session protection configuration on just one router won't work.

I'm with Levi on this one. Configuring the LDP router-ID is crucial, and it's the only option that directly addresses the requirement.
