Discuss Ericsson ECP-206 Exam Topic 1 Question 11

Review the exhibit.

A service provider wants to provide L3VPN for two customers (indicated by red and

green in the exhibit).

Referring to the exhibit, which statement is correct?

AThe two customers cannot use overlapping IP prefixes.

BMP-BGP should be configured on all the service provider's routers (Ps and PEs).

CLDP must be configured between PE and CE

DThe service provider's P routers are not aware of the customers' routes.

Suggested Answer: D

Referring to the exhibit, the correct statement is that the service provider's P routers are not aware of the customers' routes. This is because P routers only need to forward MPLS packets based on their labels, without looking into their IP headers or VPN information. The P routers do not have any VRFs configured for the customers, nor do they participate in MP-BGP sessions with other PE routers.The PE routers are responsible for maintaining VRFs for each customer and for exchanging VPN routes with other PE routers using MP-BGP910.

Wait, are we sure about A? Overlapping IPs might work in some cases.

Tiffiny 11 months ago

D is spot on, P routers don’t need to know customer routes.

Joesph 11 months ago

C seems unnecessary, LDP isn't always required, right?

Elke 11 months ago

I think B is crucial for proper routing, can't skip MP-BGP!

Shanice 11 months ago

A is definitely true, overlapping IPs would cause issues.

Mari 12 months ago

I vaguely remember that P routers don't need to know about customer routes, but I need to double-check that concept.

Melissa 12 months ago

I practiced a question similar to this, and I feel like LDP configuration is important, but I can't recall if it's mandatory between PE and CE.

Truman 12 months ago

I think MP-BGP is crucial for L3VPNs, especially for route distribution between PEs. That sounds like a strong option.

I remember that overlapping IP prefixes can be an issue in L3VPNs, but I'm not entirely sure if that's the case here.

The exhibit gives a good visual representation of the network, so I'll use that to guide my analysis of the statements.

Mertie 1 year ago

I'm not too sure about this one. I'll try to eliminate the options that don't make sense based on the information provided.

Okay, the key is to focus on the exhibit and understand the network topology. That should help me determine the correct statement.

Norah 1 year ago

Hmm, I'm a bit confused about the differences between MP-BGP and LDP. Let me re-read the question carefully.

Fannie 1 year ago

This question seems straightforward, I think I can handle it.

Okay, let me think this through. The key requirements are replicating data from location A to location B for disaster protection, and creating a read-write replica at location C. I think Oracle GoldenGate and Oracle Active Data Guard are the way to go here.

This looks like a classic permissions management question. I feel pretty confident I can solve this - I just need to make sure I fully understand the relationships between the roles and permissions described.

Ah, I think I've got it. The answer is to remove the quarantine from the message action of a filter before it can be deleted.

So, to summarize, we need MP-BGP for routing information and LDP for label distribution in this setup.

Elenor 2 years ago

Yes, Cassie. LDP is important for label distribution in L3VPN services.

Cassie 2 years ago

But don't we also need LDP configured between PE and CE for label distribution?

Thad 2 years ago

I agree with Elenor, the MP-BGP is necessary for L3VPN.

Elenor 2 years ago

I think the correct statement is B) MP-BGP should be configured on all the service provider's routers.
