  1. L1VPN Basic Mode Draft draft-fedyk-l1vpn-basic-mode-01.txt Don Fedyk (Editor) dwfedyk@nortel.com Yakov Rekhter (Editor) yakov@juniper.net Dimitri Papadimitriou dimitri.papadimitriou@alcatel.be Richard Rabbat richard@us.fujitsu.com Lou Berger lberger@labn.net

  2. Scope • Describe Basic Mode L1VPNs per the Framework • Define mechanisms and scope for Basic Mode Layer 1 VPNS • applicability of GMPLS protocols and mechanisms for basic mode draft-fedyk-l1vpn-basic-mode-01.txt

  3. Changes from 00 Version • Many Editorial Changes • Removed NSAPs no support • Made Auto-Discovery Generic added discovery information • Improved LMP Descriptions • Clarification around Stitching and Shuffling • Added the L1vpn Globally unique identifier for Signaling • Clarified recovery Procedures draft-fedyk-l1vpn-basic-mode-01.txt

  4. Basic Mode Review Signaling, (Routing) + May distributeVPN membership/reachability Signaling Only CE PE P PE CE TE link TE link May be assigned private addresses Limits LSPs to be between CEs in the same VPN MUST support LSPs between CEs, and MAY support LSPs between devices behind CEs. draft-fedyk-l1vpn-basic-mode-01.txt

  5. Basic Mode Requirements • Signaling only between CE and PE • Note: routing operates within the provider network and may be used by PEs to exchange information specific to the VPNs supported by the provider network • LSP setup, deletion, etc. by RFC 3473 signaling between the CE and the PE, and then across the provider network draft-fedyk-l1vpn-basic-mode-01.txt

  6. Features • VPN Port Index Table [Borrowed from GVPN] • Translation of CE port indexes to VPN Provider Index and Provider Port Indexes • Basic Translation mechanism for general scalable control • Allows minimal modification to Provider GVPN signaling • Define signaling procedures • VPN Addressing for CE IPv4, IPv6 • NSAP for CE removed draft-fedyk-l1vpn-basic-mode-01.txt

  7. Signaling • Signalling: CE-CE LSP setup, deletion, modification: • GVPN signalling: • information carried in RSVP-TE messages identifying a LSP (i.e. SESSION and SENDER_TEMPLATE objects) is translated by the ingress and egress PE. • single end-to-end session (i.e., CE-CE), but the identifiers of that session change along the path of the LSP. • Shuffling, Stitching/Nesting • Supported per Framework draft-fedyk-l1vpn-basic-mode-01.txt

  8. Basic Mode Discovery PPI CPI CPI AFI L1VPN Globally Unique Identifier CE PE P PE CE TE link TE link Made discovery Generic Added L1VPN Identifier for signaling PE-PE draft-fedyk-l1vpn-basic-mode-01.txt

  9. Basic Mode Signaling LSP LSP LSP Shuffling LSP 1:1 or 1:n CE PE P PE CE TE link TE link LSP LSP Stitching/Nesting draft-fedyk-l1vpn-basic-mode-01.txt

  10. Basic Mode Recovery LSP CE PE P PE CE TE link TE link A CE may request the PE-PE LSP is protected. Procedures to handle his have been specified in the GMPLS Segment Recovery Draft draft-fedyk-l1vpn-basic-mode-01.txt

  11. Next Steps • We believe the I-D is stable • Need discussion, comments on the list • Signaling extensions format is TBD • Any comments/suggestions? • Is this I-D ready for a WG document? draft-fedyk-l1vpn-basic-mode-01.txt
