Cisco Bug: CSCvs40434 - Introduce validation for a bridge domain in network-centric mode
Aug 27, 2020
- Cisco Application Policy Infrastructure Controller (APIC)
Known Affected Releases
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.
