Hi,
Section Point 5 in 7.4.1.1. Advertising C-flow Binding to P-Tunnel in draft-ietf-l3vpn-2547bis-mcast-07.txt says
"If at least some of the S-PMSIs aggregated onto the same
P-tunnel belong to different MVPNs, then all these routes MUST
carry an MPLS upstream assigned label [MPLS-UPSTREAM-LABEL,
section 6.3.4]. If all these aggregated S-PMSIs belong to the
same MVPN, then the routes MAY carry an MPLS upstream assigned
label [MPLS-UPSTREAM-LABEL]. The labels MUST be distinct on a
per MVPN basis, and MAY be distinct on a per route basis."
I do not understand where 1 label per MVPN solves everything then what is the need to use 1 label per route. What is the need to keep multiple label for a single MVPN per PE router?

Subinoy
