[alcatel-nsp] SR IPv6 transport options

Hi Chris,

The two solutions you identify are probably the best approaches.  I'd have a slight preference towards 6PE as it has wider vendor support.

Subject: [alcatel-nsp] SR IPv6 transport options

We have been testing different IPv6 transport implementations in an MPLS-enabled SR environment with RSVP-TE, and there appear to be a number of ways to deal with this.  The two we have come down to are:
                1) 6PE using ldp-over-rsvp tunnelling
                2) native IPv6 over a spoke-sdp PW mesh

Both of these provide FRR and TE over specific LSPs.  Is there any consensus as to the better approach, or is there another approach we have missed completely (to run under TiMOS 8.0R7)?

Thanks, Chris Chaundy
