it says
Option A: VRF-to-VRF connections at the AS border routers.
Option B: EBGP redistribution of labeled VPN-IP routes from AS to
neighboring AS.
Option C: Multihop EBGP distribution of labeled VPN-IP routes between
source and destination ASes, with EBGP redistribution of labeled IP
routes from AS to neighboring AS.
but in many other document, I see
Back to Back VRF connections (Option A)

发帖数: 17771 | 2 well I over looked the option C statement in the draft. it does say "labeled
IP routes" from AS to neighboring AS, that means IPv4 and labels are
distributed between the ASBRs.
so the more clear way to describe option A B C should be,
option A: VRF-to-VRF connections at the ASBRs
option B: VPNv4 distribution is done at the ASBRs by directed connected eBGP
option 1: next-hop-self
option 2: redistribute connected
option C: VPNv4 distribution is done at the RRs in each AS, and IPv4+
