Description (partial)

On the Nexus 9000 switch if traffic ingressing on peer link on one vlan, and egress out on different vlan via the same vpc peer link ports, then the hairpin traffic will be dropped. BFD echo mode is one example where BFD enabled on SVI will not establish in echo mode.

Issue happens when switch is enabled for VPC. Issue does not happen in non vpc environments.
