Cisco 350-501 Exam - Topic 3 Question 106 Discussion

Refer to the exihibit.Refer to the exhibit BGP is running in the core of the service provider to exchange routes for its customers, and OSPF serves as the PE-CE routing protocol. The service provider s existing customer at CE1 is opening a new office in a different geographical location connected via CE2. A network engineer must update the BGP implementation so that PE1 and PE2 will share routes and provide communication between CE1 and CE2 Which action must the engineer take?
A) Configured CE2 to establish a BGP relationship with PE1 and PE2
B) Configure CE1 and CE2 with a pseudowire that will run over the service provider core.
C) Configure PE1 and PE2 to mutually redistribute BGP and OSPF in the VRF for the customer.
D) Configure PE1 and PE2 to redistribute OSPF from the VRF for the customer into BGPPUM

Show Suggested Answer Hide Answer
Suggested Answer: A

The weight parameter in BGP (Border Gateway Protocol) is a Cisco-specific attribute that is local to the router on which it is configured. It is used to prefer one path over another when multiple paths to the same destination are available. The weight is not advertised to other routers, making it a local parameter.

I recall that in a previous exam, we had to set up BGP relationships directly between CE devices. So, A might be a valid option, but I’m not completely convinced.

I'm a bit confused about whether we need to focus on BGP or OSPF more. I thought D could be a possibility since it mentions redistributing OSPF into BGP.

Okay, I think I've got it. The question is asking us to update the BGP implementation to allow communication between the two CE routers. Based on the information provided, the best approach seems to be configuring the PE routers to redistribute the OSPF routes from the customer VRF into BGP. That way, the routes will be shared across the core and the two CE routers can communicate. I'm confident this is the right solution.

Hmm, this is a tricky one. I think the key is in how the PE and CE routers are communicating. If it's just OSPF between them, then the BGP routes in the core won't be shared automatically. I'm leaning towards the option that has the PE routers redistributing between BGP and OSPF, but I want to double-check that to make sure I have the right understanding.

Okay, let me think this through. Since BGP is running in the core, I'm guessing the solution has something to do with configuring BGP on the CE routers to connect the two sites. But I'm not sure if that's the right approach, or if there's a more efficient way to handle this using the existing OSPF setup. I'll need to carefully consider the options.

This question seems straightforward, but I want to make sure I understand the key details before answering. The service provider is using BGP in the core and OSPF between the PE and CE routers, and the customer is opening a new office that needs to communicate with the existing one. I think the key is figuring out how to get the routes shared between the two CE routers.

Option B is an interesting idea, but setting up a pseudowire just to connect two sites in the same network seems like overkill. I'm glad the correct answer is more straightforward.
