Hi All:
I am using 6807-XL with Sup6T for a campus MPLS network. I've setup A-VPLS between to deliver a couple VLANs across the MPLS. I would like to be able to pass spanning-tree (rapid-pvst) across the VPLS, but can't seem to figure out how to do that or if it is even supported. I've connected 2 switches together downstream from 2 PE's to create a spanning-tree loop, however one of the ports goes into "l2ptguard error disable"instead of what I expected which is spanning-tree blocking a port. I don't believe STP bpdu's are being sent over the VPLS. Is passing spanning-tree even supported?
