How would this effectively be different from using GLBP to do multiple outbound path routing on two 6513s ? If I have 2 6513s cross-connected to 4 x 3750E stacks with a dozen servers connected to each 3750E stack ( the 3750Es are doing Layer 2, not L3 – its an IBM requirement ) with the servers having a GLBP provided default gateway on the 6513 vlans – would I not get essentially the same thing ? I ask because having looked at port channel interface counters between port channel connected 3750E clusters before I don’t always see 1:1 counters.
