The reason Why I asked this question. considering following scenario
(i) RSTP PVST enabled three switches connected to ACI Fabric A, B & C ( link type rstp shared)
(ii) VLAN10, VLAN 20, VLAN30 are created on the switches and permitted over the uplinks (trunk) connected to ACI
(iii) A is the root bridge and has endpoints for VLAN 10, 20 , 30 & B also has endpoints connected to it in VLAN 10, 20 & 30
(iv) C switch has no endpoints connected for any VLANs
I believe that all three A, B, C switches generate BPDUs with VLAN tags. would like to know if the BPDUs are still flooded to the Leaf switch port where the switch " C" connected to . because, "C" switch has no endpoints connected in any VLANs. but, "C" will also be sending the BPDus with all VLAN tags.
in this case, does ACI leaf register the port for Multicast group :-)
Could someone clarify. I observed that ACI didnt forward BPDUs to "C" switch sometimes when there were TCN changes were seen and "C" started claiming to be the root switch.
Thank you in adavnce
