I have two 6509 Switches at the Core working redundant to each other. My servers would be directly connecting to one of the module in the Core. I have some application servers which are using Microsoft NLB. As of now they are connected to one 3560 switch where i am able to do NLB using static entry. Now i want to connect the servers to the core switch, for redundancy i would like to connect all primary servers on core 1 and all redundant servers on core 2. There is a l2 trunk (etherchannel) is there between these two core switcehs. Is it possible to connect 2 servers in 2 different switches and do the load balancing.
