I have a scenario of 3 PE routers with full mesh VPLS Pseudo-wires configured over it. If you look into the design, I have connected two switches Sw1 and Sw2 with the PEs R2 and R3 respectively. Considering that the VPLS cloud is operating correctly, I have connected a CE switch [Sw3] with Sw1 and Sw2. Now, the issue is STP over VPLS. Without having STP running inside the VPLS cloud, it's causing loop all over the ring.
In order to avoid loop, I have run PVST+ on all the three switches but the PEs are not running STP as I believe that the BPDUs are to be transparently forwarded through the VPLS pseudo wires. But, i'm not really sure why i'm getting PVST_Inc error on both Sw1 and Sw2 for the links that are connected with their respective PEs. Any response regarding this will be highly appreciated.
