Alvaro, Section 3 of draft-previdi-spring-problem-statement-01 still contains the following:
"The source-based routing model, applied to the MPLS dataplane, offers the ability to tunnel services (VPN, VPLS, VPWS) from an ingress PE to an egress PE, without any other protocol than IGPs (ISIS or OSPF). LDP and RSVP-TE signaling protocols are not required." The above claim about the ability to tunnel services "without any other protocol than IGPs" is misleading, as VPN and VPLS services may use p2mp LSPs, and neither ISIS nor OSPF provide any capability for setting up such LSPs. Moreover, the claim about "LDP and RSVP-TE signaling protocols are not required" is misleading as well, as p2mp LSPs are signaled using either mLDP (which is build as an extension to LDP) or RSVP-TE. Zhenbin(Robin) pointed to this in his e-mail (see http://www.ietf.org/mail-archive/web/spring/current/msg00727.html) Furthermore, the above claim is incorrect if the ingress and egress PEs are in different autonomous systems.
