Hi

I have three 6400 switches , I need to make LAG on one switch. And LAG on other two separated switches.

Is that possible ?

I am adding a simple diagram to demonstrate the idea.

So guys is that possible?

What do you want to achive with that?

A Lag Spanning Multiple Chassis is not supported by 6400.

It works on 6900 (MC-LAG/Virtual Chassis) and 9000 (MC-LAG)

DHL would be an Idea but this only creates a single LAG at the "bottom" switch facing up and a single LAG on each top switch facing down.

To be more clear . we have two MPLS in two different locations connecting to the head office. We want to create active passive link . see attached draw.

So is that doable? Any suggestions ? [attachment=-1]uploadfromtaptalk1399896778260.jpg[/attachment]
