Dear all,

We just submitted new draft 
(http://www.ietf.org/internet-drafts/draft-cao-pwe3-mpls-tp-pw-over-bidir-lsp-00.txt), 
it defines extensions to LDP for explicit PW to transpprt LSP mapping that 
make sure both ends of a PW select and bind to the same bidirectional LSP or 
use unidirectional LSPs with congruent paths.

Any comments are appreciated!

Best regards,
Mach
