Cisco 300-510 Exam - Topic 13 Question 92 Discussion

Refer to the exhibit.BGP is running on the network, and CE1 currently prefers routes to the internet via PE 1 A network engineer must manipulate the BGP routes that CE1 receives from PE2 to be more desirable The engineer configured a route map using MED and applied it on CE1 outbound from PE2. However, after a BGP soft reset. PE1 is still preferred. Which action must the engineer take so that PE2 is chosen as the next hop?
B) Configure the route map with MED and local preference to manipulate the route outbound
A) Update the route map to use only weight to manipulate the path.
C) Apply the route map on CE1 In the inbound direction.
D) Configure the route map with AS path prepend to manipulate the AS path to exit the autonomous system

D could work, but it's a bit of a roundabout way.

C seems off, it should be outbound, not inbound.

AS path prepending sounds familiar, but I don’t recall if it would help in this scenario. I guess option D could be a possibility, but I’d need to think it through more.

I’m a bit confused about the direction of the route map. I thought applying it inbound might change the preference, so option C seems plausible, but I’m not certain.

I think using local preference along with MED could be the right approach, like in that practice question we did last week. So maybe option B?

I remember studying how weight is preferred over MED in BGP, so maybe option A could work, but I'm not entirely sure.

Prepending the AS path could work, but I'm not sure if that's the most elegant solution here. I'll need to carefully consider the tradeoffs between the different options.

Ah, I see. Manipulating the weight or local preference could be a good approach to influence the BGP decision. I'll need to review the details on how those attributes impact path selection.

Okay, I think I understand the key issue here. We need to make the routes from PE2 more desirable to CE1 than the routes from PE1. The route map using MED didn't work, so I'll need to explore the other options.

Hmm, this looks like a tricky BGP routing question. I'll need to carefully consider the options and think through the BGP path selection process.

Hmm, I'm a bit unsure about the inbound versus outbound direction for the route map. I'll need to double-check the BGP best path selection criteria to make sure I apply the route map correctly.

Okay, I've read through the options a few times now. I think option D is the best fit - it talks about a quantitative measure of the level of service, which seems to be the core of what an SLI is.

This seems pretty straightforward. The difference between public and private SLBs is that private ones use the internal network while public ones use the internet, so I'll go with A.

Haha, I bet the engineer is regretting not using the 'make PE2 the cool kid' option on the route map. Maybe they should try the 'bribe PE2 with cookies' technique next.

I'm with Afton on this one. Applying the route map inbound is the way to go. Who wants to mess with AS path prepending when you can just tweak the local pref?

D seems like a good option too. Prepending the AS path can make the route less desirable and push CE1 to prefer the PE1 path.

That's a good point. Applying the route map on CE1 in the inbound direction might also help.

The route map is being applied outbound, so I think C is the correct answer. Applying it inbound would allow us to manipulate the routes received from PE2.

Yes, you are right. By applying the route map on CE1 in the inbound direction, we can manipulate the routes received from PE2 to make PE2 the preferred next hop.
