B is also a contender, but A is definitely the right choice here.

Wait, really? I didn’t know eBGP was prioritized like that!

Moon 11 months ago

Totally agree with A! Makes sense.

Garry 11 months ago

I thought it would be D, shortest AS path usually wins.

Margart 11 months ago

A is correct, eBGP routes are prioritized first.

Eric 11 months ago

If I recall correctly, the lowest origin is usually important, but I can't remember if it beats the eBGP preference in this case.

Bette 11 months ago

I'm a bit confused about the AS path and how it interacts with the other options. Does ignoring it really change the selection order?

Joaquin 12 months ago

I remember practicing a question similar to this, and I think the lowest Origin might come into play after the eBGP preference.

I think the command is supposed to prioritize eBGP routes, but I'm not entirely sure if that's the first selection criteria.

Ah, I see. That means the route with the lowest origin type should be selected first. I'll double-check the order of the BGP decision process to confirm.

Hector 1 year ago

Okay, I think I've got this. The "as-path-ignore" command means the AS path length is ignored, so the route selection will be based on the next criteria in the decision process, which is the origin type.

Hmm, the "as-path-ignore" command is throwing me off a bit. I'll need to make sure I understand how that changes the normal BGP decision process.

Keith 1 year ago

This question is testing my understanding of the BGP decision process, so I'll need to carefully review the steps and how the "as-path-ignore" command affects the selection.
