draft-ietf-l1vpn-basic-mode-00.txt Scope Describe Basic Mode L1VPNs as per the Framework Define mechanisms and scope for Basic Mode Layer 1 VPNS applicability of GMPLS protocols and mechanisms for basic mode
3
draft-ietf-l1vpn-basic-mode-00.txt Basic Mode Review PEP CE Signaling Only Signaling, (Routing) + May distribute VPN membership/reachability 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.
4
draft-ietf-l1vpn-basic-mode-00.txt 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
5
draft-ietf-l1vpn-basic-mode-00.txt Features VPN Port Index Table (PIT) Translation of CE port indexes (CPI) to VPN Provider Index (VPN-PPI) and Provider Port Indexes (PPI) Basic Translation mechanism for general scalable control Allows minimal modification to Provider GMPLS signaling Define signaling procedures VPN Addressing for CE IPv4, IPv6

7
draft-ietf-l1vpn-basic-mode-00.txt Signaling Signaling: CE-CE LSP setup, deletion, modification: GMPLS signaling: 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-ietf-l1vpn-basic-mode-00.txt Basic Mode Recovery PEP CE TE link LSP A CE may request the PE-PE LSP is protected. Procedures to handle his have been specified in the GMPLS Segment Recovery Draft

draft-ietf-l1vpn-basic-mode-00.txt Next Steps Signaling extensions :Other Signaling Format of Filtered Record route object is TBD Is this needed? Minor revision and WG last call Any other comments/suggestions?
