I am doing some testing with a handful of RB760iGS running 6.49.7 regarding MPLS/VPLS with LDP neighbors. If you view the diagram below I have MPLS/VPLS/LDP running without issue in the black circle. However, I can not get MPLS/LDP running in the red circle despite my best efforts. I placed a small unmanaged switch between the two routers in the red circle and started a packet capture and can see the LDP hello packets.
I am at a loss, I tried first in EVE-NG, reconfiguring from scratch, and finally moving to physical gear with no success. Any suggestions would be greatly appreciated.
