Description (partial)

Symptom:
When performing a network-centric migration to Cisco ACI, the surrounding network usually can handle only 1 EPG per bridge domain. If the surrounding network is not ready, there could be loop in the network.

Conditions:
This issue occurs in the following situation:

1. You configure two EPGs using different VLANs in the same bridge domain.
2. You extend the VLANs to a Nexus 7000 that performs all the routing for the bridge domains.

This causes two issues:

1. Broadcast and Unknown Unicast traffic sent in VLAN X is replicated back down to the Nexus 7000 in VLAN Y, causing a move.
2. In Cisco ACI, traffic for the gateway MAC address moves between the two EPGs.
