    I have a server with a loopback that I want to routing.

    I have a server with 2 NICs in different network addresses in 2 switch core for redundance (interconnected between them).

    I have an application that can be Access with the ip address of the loopback.

    Can I do that?, how?

    (I have the configuration of the switches, and the configuration of the NICs and the loopback, I know that I need more configuration in the Windows server, if it is possible)

      hmm…i’m not a server admin guy but from the networking perspective I think that you need a routing process on the server that will announce a loop IP address over your NICs
