Discuss Cisco 350-501 Exam Topic 3 Question 108

Refer to the exihibit.

Refer to the exhibit. The operations team is implementing an LDP-based configuration in the service provider core network with these requirements:

R1 must establish LDP peering with the loopback IP address as its Router-ID.

Session protection must be enabled on R2.

How must the team update the network configuration to successfully enable LDP peering between R1 and R2?

AChange the LDP password on R2 to Cisco.

BConfigure mpls ldp router-id loopback0 on R1 and R2.

CConfigure LDP session protection on R1.

DChange the discover hello hold time and interval to their default values.

Suggested Answer: A

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

Howard 11 months ago

Session protection on R2 is a must, but B is still key.

Gerald 11 months ago

Wait, why would we change the LDP password? Seems unnecessary.

Bok 11 months ago

I agree, B makes the most sense here.

Jame 12 months ago

Option B is definitely the way to go.

Natalie 12 months ago

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

Tamekia 1 year ago

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.

Ngoc 1 year ago

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.

Veronique 1 year ago

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.

Veda 1 year ago

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.

Leontine 1 year ago

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.

Sherron 1 year ago

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.

Antonio 1 year ago

Hmm, I'm a bit unsure about the session protection requirement. I'll need to review my notes on that.

Leandro 1 year ago

This looks like a pretty straightforward MPLS configuration question. I think I can handle this one.

Lynette 1 year ago

Option D? Really? What is this, a trick question? Changing the default timers won't solve the LDP peering issue.

Hassie 1 year ago

Haha, I bet the correct answer is hidden in the exhibit somewhere. Gotta love these tricky certification questions!

Jacinta: Sounds good, let's update the configuration accordingly.

Jillian 1 year ago

↳ replying to Hassie

User 3: I agree, let's go with that option.

Jacinta 1 year ago

↳ replying to Hassie

User 2: Yeah, that makes sense. It mentions using the loopback IP address as the Router-ID.

Tambra 1 year ago

↳ replying to Hassie

User 1: I think the answer is B) Configure mpls ldp router-id loopback0 on R1 and R2.

Celeste 1 year ago

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.

Brinda 1 year ago

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.

Man 1 year ago

↳ replying to Brinda

It's important to follow the requirements closely to ensure everything works as intended.

Alpha 1 year ago

↳ replying to Brinda

Definitely, that's the key to successfully enabling LDP peering between the two routers.

Floyd 1 year ago

↳ replying to Brinda

I agree, configuring the LDP router-ID on both R1 and R2 is the way to go.

Levi 2 years ago

Option B seems like the way to go. Setting the LDP router-ID on both R1 and R2 is key to establishing the peering session.

Paola 1 year ago

↳ replying to Levi

Yes, that's correct. It ensures that the peering session is established successfully.

Barbra 1 year ago

↳ replying to Levi

I agree, setting the LDP router-ID on both R1 and R2 is crucial for the peering session.

Glendora 2 years ago

I'm not sure about that. Maybe we should also consider enabling LDP session protection on R1 for added security.

Argelia 2 years ago

I agree with Robt. Setting the router-id to loopback0 will ensure successful LDP peering.

Robt 2 years ago

I think the answer is B) Configure mpls ldp router-id loopback0 on R1 and R2.
