Thank you! Very helpful information collected together in one document. It would be also great to add information how to configure different VPC implementations to work with the provided solutions. For example, I'm thinking about having a few subnets...
it's because of the fragmentation and VFR enabled on the router. Try the workaround. Disable VFR on all interfaces (no ip virtual-reassembly"), or just on these where the command "show ip virtual-reassembly" shows you reassembly count > 0
