Claim Text:
1. A method for managing virtual network instance (VNI) to virtual local area network (VLAN) mapping conflicts for a dual-homed server communicably connected to a first peer leaf and a second peer leaf over a virtual port channel (vPC), the method comprising: receiving, at the first peer leaf from the second peer leaf, information identifying a first VNI as being mapped to a second VLAN at the second peer leaf, wherein the first VNI is being mapped to a first VLAN at the first peer leaf; receiving, at the first peer leaf from the dual-homed server, a request for a VLAN mapping for a virtual machine associated with the first VNI; detecting, in response to receiving the request, that the first VLAN is different to the second VLAN; and in response to detecting the first VLAN is different from the second VLAN, blocking a link over the first VLAN connecting the first peer leaf to any virtual machine associated with the first VNI at the dual-homed server.
