I have three switches I am trying to traffic to flow through. 1 is a 7020 and 2 are are 7060s. They form a triangle. Above the 7020 is a firewall/router, below the 7060s are ESXi hosts.
I have found lots of documentation about MLAG between 2 switches, but I can’t find anything for 3 or more. Can anyone educate me if I can add a 3rd port into the MLAG config on each switch so that the 7020 peers with both 7060s and the 7060s peer with the opposite 7060 and 7020?
You can have MLAG only between 2 switches. Can you elaborate on why you want 3 switches as MLAG. If I understand this correctly, your setup looks like below:
You can configure 2 7060s as MLAG. And configure a port-channel to connect to 7020 to trunk traffic from firewall connected to 7020 to ESXi hosts connected to 7060.
