have one query
Spanning-tree root switch --> Nexus Layer 2 Aggregation switches( VPC)-->ACi Fabric---> 4 Access switches
As far as BPDUs are concerned, ACI is a hub. if We connect switches which are in RSTP ( as above) and there is DISPUTE detected on Nexus Layer 2 Aggregation switches ( VPC) and blocked the port ( root guard also enabled on VPC connected to ACI fabric)
I understood that the Dispute message is because of the inferior BPDUs and root guard enabled on nexus VPC. in this case, does the blocked port ( due to dispute) send BPDUs to other switches through ACI fabric?
All the access switches interfaces are in Point to point ( not in shared :-( )
Thank you in advance
