Nice job! BGP is such a beast! Definitely helps to see this in action. Brings an understanding to why a transit layer could be a benefit.
Thanks for the feedback Brent, and I couldn't agree more!
This is such a game changer if you peer with 2 providers or even have 2 circuits from the same provider. Make sure to check out the github account to get access to the entire lab config files and the failover scripts.
Thank you that was very interesting!
Glad you enjoyed it! I've failed over many datacenters with this exact method. BGP over the internet is not a science, but more of an art. There are so many different ways to do the same thing.
Awesome video, thanks for the clear explanation.
Glad it was helpful!
Your video was really awesome! Just drop the Daikiri bar music, please :) It's not necessary at all.
Were you using Physical Lab setup or something else ? Looks nice video !!
Hey Neal. I am using the community edition of EVE-NG.
Thanks SIR ! Nice job ! very good explanation and I like the way you explain too. helped me a lot and I am sure others too.
I like your keyboard. can you share the brand and model please ?
Nice job. I'm from a Juniper background and can complete a 2 x DC Failover as per your video with no problem. But now I have inherited a poorly designed Cisco Network that has a C6880X VSS with two x External links. There is no auto failover if the main link goes down. So, my question; how can I get the same failover on a single VSS with two links that are upstream to another 2 x DC?
Are you using BGP to peer with the provider? It should be similar. If it is just default routing with the ISP, then you would want to setup a default route with IP SLA tracking or some metric to move the route from one ISP to the other.
On the lab config files the routers only have two interfaces configured with IP addresses but there are three connections, am i missing something how do we set the lab up?
