Hi Shane, Your suggestions below look good, I just have a comment on the following text: "8. Define requirements and solutions for Auto-Discovery and Signaling of Inter-AS unicast VPLS and VPWS L2VPN's, in addition to Inter-AS multicast VPLS and VPMS Layer-2 VPN's." It is understood that there may be other use cases or VPLS solutions where additional multicast optimizations may be required as described in the drafts you listed below. Still "Inter-AS unicast VPLS" suggests that the VPLS solutions developed up to now where not able to transport multicast at all. Or I am aware of some large HVPLS deployments handling multicast applications, including heavy ones like IP TV. Will it be possible to use instead the following text for 8: "8. Define requirements and solutions for Auto-Discovery and Signaling of Inter-AS VPLS and VPWS L2VPN's, in addition to Inter-AS solutions for multicast-optimized VPLS and VPMS Layer-2 VPN's."
