Cisco Exam 350-501 Topic 3 Question 109 Discussion

Actual exam question for Cisco's 350-501 exam

Question #: 109
Topic #: 3

Refer to the exihibit.

Refer to the exhibit. Routers R1 through R5 are being deployed within the core of a service provider running BGP The core supports distribution of VPNv4 routes using MPLS. R3 currently has multiple paths to reach R4. A network engineer must implement BGP attributes so that R3 can reach R4 via R1. Which action must the engineer take to meet the requirement?

AConfigure R3 so the route to R4 through R1 will have a higher weight than the route from R2 or R5.

BConfigure R2 to send the route from R4 to R1 using a higher metric than what is advertised to R3.

CConfigure R5 to send the route from R4 to R1 using a longer AS path than the AS path that it receives from R1 or R2.

DConfigure R3 so the route to R4 through R1 will have a lower local preference than the route from R2 or R5

Show Suggested Answer

Suggested Answer: A

To direct traffic from R3 to R4 via R1, the weight attribute on R3 can be set higher for the route through R1 compared to other routes. Weight is a Cisco-specific BGP attribute that determines the preferred path when multiple routes to the same destination exist. It is local to the router on which it is configured and not advertised to other BGP peers.

Hey, at least it's not a Cisco IOS syntax question, right? I'm feeling good about A.

I agree with Farrah, a longer AS path would be a more reliable way to ensure R3 reaches R4 via R1.

I think Aracelis is right, configuring R5 to send the route with a longer AS path makes more sense to me.

Hmm, this is a tricky one. I'm leaning towards B, but I could be wrong.

I'm pretty sure C is the right answer. Messing with the AS path is the way to go here.

I agree, tweaking the AS path is a common practice in BGP to influence routing decisions.

Yeah, manipulating the AS path is a common way to control routing. Good choice.

I think C is the best option too. Changing the AS path should do the trick.

But wouldn't configuring R3 with a higher weight for the route to R4 through R1 ensure that it takes that path?

I think the answer is A) Configure R3 so the route to R4 through R1 will have a higher weight than the route from R2 or R5.
