Hi, We received lots of comments on the initial version. The draft was updated and we included a new author.
This draft tries to bring up a simple solution for egress PE protection. It is easily to be deployed and brings no big change. Welcome your comments on the mailing list and at the Vancouver meeting. Thanks, Mingui PS: I copied this email to the pwe3 mailing list since there is a companion draft: ICCP Application TLVs for VPN Route Label Sharing, http://tools.ietf.org/html/draft-zhang-pwe3-iccp-label-sharing-00 >-----Original Message----- >From: [email protected] [mailto:[email protected]] >On Behalf Of [email protected] >Sent: Monday, October 21, 2013 4:42 PM >To: [email protected] >Subject: I-D Action: draft-zhang-l3vpn-label-sharing-01.txt > > >A New Internet-Draft is available from the on-line Internet-Drafts directories. > > > Title : Label Sharing for Fast PE Protection > Author(s) : Mingui Zhang > Peng Zhou > Russ White > Filename : draft-zhang-l3vpn-label-sharing-01.txt > Pages : 13 > Date : 2013-10-21 > >Abstract: > This document describes a method to be used by Service Providers to > provide fast protection of VPN connections for a CE. Egress PEs in a > redundant group always assign the same label for VPN routes from a > VRF. These egress PEs create a BGP virtual Next Hop (vNH) in the > domain of the IP/MPLS backbone network as an agent of the CE router. > Primary and backup tunnels terminated at the vNH are set up by the > BGP/MPLS IP VPN based on IGP FRR. If the primary egress PE fails, the > backup egress PEs can recognize the "shared" VPN route label, so that > the failure affected traffic can be smoothly switched to the backup > PE for delivery without changing its VPN route label. > > >The IETF datatracker status page for this draft is: >https://datatracker.ietf.org/doc/draft-zhang-l3vpn-label-sharing > >There's also a htmlized version available at: >http://tools.ietf.org/html/draft-zhang-l3vpn-label-sharing-01 > >A diff from the previous version is available at: >http://www.ietf.org/rfcdiff?url2=draft-zhang-l3vpn-label-sharing-01 > > >Please note that it may take a couple of minutes from the time of submission >until the htmlized version and diff are available at tools.ietf.org. > >Internet-Drafts are also available by anonymous FTP at: >ftp://ftp.ietf.org/internet-drafts/ > >_______________________________________________ >I-D-Announce mailing list >[email protected] >https://www.ietf.org/mailman/listinfo/i-d-announce >Internet-Draft directories: http://www.ietf.org/shadow.html >or ftp://ftp.ietf.org/ietf/1shadow-sites.txt
