Hope that someone can point me in the right direction.
We have a 5580 that we want to connect to each of our 7K's as an internal firewall. To minimize hassle, we will setup the ASA in transparent mode.
I have been working on this all day today and have run into a stopping point. If I put vlan 20 on a subinterface on Te7/0 which will connect to N7K_1 it works great. When I try to put that same vlan on Te7/1 which connects to N7K_2, I get an error that says the vlan is already assigned to another interface.
Our local Cisco SE told us that this would work. When I called TAC today for help, they said it wasnt supported and wouldnt work.
My problem is that not all of our servers/systems are dual homed to both 7K's so I have to be able to get this to work because of potential asymmetric routing issues that we will be dealing with.
Has anyone been able to get the 5580 to work in this configuration and can you share your config with me ?
Using the redundant interface command isnt an option because I need for both interfaces to be able to route over both 7K's at all times.
Any suggestions will be appreciated.
