Refer to the exhibit.
Refer to the exhibit. The default route is not present in the routing tables of the Cisco ACI leaf switches. All static and direct routes are currently being redistributed and advertised. Which jn must be taken to advertise a default route on the eBGP L30ut?

Wait, can you really use a null next-hop for this?

I think option B is the way to go!

A default route is essential for proper routing.

Definitely not C, that won't work here.

I agree, B seems like the best choice!

Implementing an export route map seems familiar, but I can't remember if it was for default routes or something else.

I feel like enabling a BGP peer prefix policy was mentioned in our notes, but I can't recall if it applies to default routes specifically.

I think we practiced a similar question where we had to create a route leak policy. Could that be the answer?

I remember discussing default routes in our study group, but I'm not sure if a static default route is the right approach here.

This seems straightforward to me. Option D looks like the way to go - implementing an export route map to match the 0.0.0.0/0 default route and advertise it. I'll select that and move on to the next question.

I'm a bit confused by the terminology here. Can someone explain what a "Default Route Leak Policy" is and how that would work to advertise the default route? I want to make sure I understand this properly.

Okay, I think I've got this. The key is to find the right way to inject the default route into the eBGP L3Out. I'm leaning towards option B, but I'll double-check the details.

Hmm, the default route is not present in the routing tables, so I'm guessing we need to do something to advertise it. Let me think through the choices...

This looks like a tricky networking question. I'll need to carefully review the options and think through the implications of each approach.

I'm feeling a bit 'default-y' today, so I'm going with B. Leak that default route, baby!

I hope the answer isn't A, that would be like trying to plug a black hole with a default route. Yikes!

I'm torn between B and D, but I'm leaning towards B. Seems like the more elegant solution.

C is the answer, no doubt. Enabling a BGP peer prefix policy set to Always is the way to go.

D looks good to me. An export route map matching 0.0.0.0/0 should do the trick.

I think the answer is B. Creating a Default Route Leak Policy on the L3Out seems like the most straightforward way to advertise a default route.

I think enabling a BGP peer prefix policy set to Always could also work.

But what about configuring a static default route on the ACI node profiles with next-hop null?

I agree, creating a Default Route Leak Policy on the L3Out makes sense.

But wouldn't creating a Default Route Leak Policy on the L3Qut also work? That's option B.

I disagree, I believe the correct answer is D) Implement an export route map matching 0.0.0.0/0.

I think the answer is A) Configure a static default route on the ACI node profiles with next-hop null.
