Hi John, It is not clear to me 1) how the proposed solution works in Figure 1 situation of the draft. Even the receiver B assigns the same label for all five sub-LSPs, because there are intermediate nodes between A and B, the sender A will be asked to use the different labels for five sub-LSPs, is that right? 2) For the following MLSP case, do sub-LSPs start from node A or from node W? --L-- --P-- / \ / \ A------W S---Q---B \ / \ / --M-- --R-- Thanks, Lucy > -----Original Message----- > From: mpls-bounces@ietf.org [mailto:mpls-bounces@ietf.org] On Behalf Of > John E Drake > Sent: Tuesday, July 06, 2010 11:11 AM > To: curtis@occnc.com; stbryant@cisco.com > Cc: draft-ietf-pwe3-fat-pw@tools.ietf.org; mpls@ietf.org; pwe3 > Subject: Re: [mpls] [PWE3] Multiple RSVP paths > > Hi, > > A related ID: > > http://www.ietf.org/id/draft-kompella-mpls-rsvp-ecmp-00.txt > > Thanks, > > John > > -----Original Message----- > > From: pwe3-bounces@ietf.org [mailto:pwe3-bounces@ietf.org] On Behalf Of > > Curtis Villamizar > > Sent: Tuesday, July 06, 2010 8:30 AM > > To: stbryant@cisco.com > > Cc: draft-ietf-pwe3-fat-pw@tools.ietf.org; pwe3 > > Subject: Re: [PWE3] Multiple RSVP paths > > > > > > In message <4C31E719.1060402@cisco.com> > > Stewart Bryant writes: > > > > > > In response to a comment received during last call I have added a new > > > section 7.3 entitled : "Multiple RSVP-TE Paths" which says: > > > > > > In some networks it is desirable for a Label Edge Router (LER) to be > > > able to load balance a PW across multiple RSVP-TE tunnels.
