[Pce] FW: I-D Action:draft-ietf-pce-brpc-09.txt

[JP Vasseur <jvasseur at cisco.com>]

Dear all,

We made a minor change to the ID, addressing a comment from Mach Chen. The
document will soon be back to the Publication Request state.

   A PCE that can compute the requested path for more than one
   consecutive domain on the path SHOULD perform this computation for
   all such domains before passing the PCRep to the previous PCE in the
   sequence.

Cheers,

JP.
