Description (partial)

When a vPC VLAN is made into a non-vPC one on a vPC switch and if it had the lowest numbered vlan-id among the vPC vlans on that peer, then it will cause vPC forwarder election to fail if that same vlan doesn't exist on the other vPC switch(peer).

The issue happens only when the lowest number vPC vlan on a vPC peer is made into a non vPC one.
