Hi Marko, Port fa0/0.211 of on R2 is encapsulating DOT1Q for VLAN 211. Whereas Port fa0/1.52 of on R5 is encapsulating DOT1Q for VLAN 52. Since the VLANS are Tunneled using the AToM Switch SW1 end up receiving BPDU's of SW3 for VLAN52 on the port connected to R2 (VLAN211) and vice-verse. I guess BPDU filtering will be a solution. I will try it out.This is my analysis to the situation. Let me know whats yours.
On the other hands, I worked on this LAB on Procotor Labs VRacks I never faced this issue with inconsistencies. Why? Please provide your feedback.
