Ok so I have a question about back to back VPC configuration.
I have a back to back VPC from core to agg layer so that I have 2 logical switches in my path.
However I am seeing an issue on the agg layer. Traffic is traversing the VPC peerlink instead of being sent up to the core which is where the spanning-tree root is configured.
Po1 is my uplink from the agg
Po4 is my vpc peerlink on the Agg
Po1 Root FWD 200 128.4096 (vPC) P2p
Po2 Desg FWD 200 128.4097 (vPC) P2p
Po4 Root FWD 330 128.4099 (vPC peer-link) Network P2p
Eth2/6 Altn BLK 2000 128.262 P2p
