Hi Sir, Does this work if we have ebgp & ibpg setup in our environment. i.e. one path to reach destination is ebgp & other is through ibgp then ebgp. This is kind of redundancy setup. Please advise.
No, they would both have to be the same. If one was eBGP and the other iBGP, the E path is always preferred in IOS because E has an AD of 20, where i has an AD of 200. Multipath only comes into play deep down the best path algorithm. You can read more here: journey2theccie.wordpress.com/2021/02/19/configuring-bgp-best-path-algorithm-on-cisco-ios-a-deep-dive/
Great video. One suggestion: make sure that your examples work when they should. I know it's not relevant to the topic at hand, but for those of us who are here to learn it's difficult to trust what you've done is correct without actually seeing it work. Keep up the great videos!
Thanks Mike! As a 15 year CCIE veteran, a new job has made me go back to basics and I am loving your videos! Keep up the good work.
Great tutorial man. This helped. I couldn't understand why the eBGP routes weren't multipathed until I found this. Thanks
Good lecture, Tks for sharing
Nice tutorial Michael..I liked it :)
what makes the routes come back the same way they came in ? (in case you have FWs on each segment) tnku I understand outbound theory
