REAL WORLD SCENARIO
I have a real world scenario that I hope you guys can help with... So here we go:
Site A has 2 Nexus 5000 and Site B has 2 Nexus 5000. There is one MetroE that connects SiteA with SiteB. This is all Layer 2 and not Layer 3. I want to take another MetroE from a different provider for Redundancy and connect the two sites.
This customer is huge and 24 Hrs operation.
1) How can I connect the second MetroE without interrupting anything?
2) How can I make the current one primary and if it goes down for the second one to take over?
Remember, all Layer 2 and no Layer 3. I want to do this with little to none interruptions.
thanks for your input.
