A new IETF working group has been formed in the Internet Area of the IETF. For additional information, please contact the Area Directors or the WG Chairs. Layer 2 Virtual Private Networks (l2vpn) ---------------------------------------- Current Status: Active Working Group Chair(s): Rick Wilder <rwilder@masergy.com> Vach Kompella <vkompella@timetra.com> Loa Andersson <loa@pi.se> Internet Area Director(s): Thomas Narten <narten@us.ibm.com> Erik Nordmark <erik.nordmark@sun.com> Internet Area Advisor: Thomas Narten <narten@us.ibm.com> Technical Advisor(s): Russell Housley <housley@vigilsec.com> Alex Zinin <zinin@psg.com> Mailing Lists: General Discussion: l2vpn@ietf.org To Subscribe: https://www1.ietf.org/mailman/listinfo/l2vpn Archive: https://www1.ietf.org/mail-archive/working-groups/l2vpn/current/maillist.html Description of Working Group: Alex Zinin is the routing advisor. Russ Housley is the security advisor. This working group is responsible for defining and specifying a limited number of solutions for supporting provider-provisioned layer-2 virtual private networks (L2VPNs). The WG is responsible for standardization of the following solutions: 1. Virtual Private LAN Service (VPLS)--L2 service that emulates LAN across an IP and an MPLS-enabled IP network, allowing standard Ethernet devices communicate with each other as if they were connected to a common LAN segment. 2. Virtual Private Wire Service (VPWS)--L2 service that provides L2 point-to-point connectivity (e.g. Frame Relay DLCI, ATM VPI/VCI, point-to-point Ethernet) across an IP and an MPLS-enabled IP network. 3. IP-only L2 VPNs--L2 service across an IP and an MPLS-enabled IP network, allowing standard IP devices to communicate with each other as if they were connected to a common LAN segment or a point- to-point circuit. The WG will address intra-AS scenarios only at this point (other scenarios will be considered for inclusion in the updated charter when the current one is completed.) As a general rule, the WG will not create new protocols, but will provide functional requirements for extensions of the existing protocols that will be discussed in the protocol-specific WGs. As a specific example, this WG will not define new encapsulation mechanism, but will use those defined in the PWE3 WG. L2VPN WG will review proposed protocol extensions for L2VPNs before they are recommended to appropriate protocol-specific WGs. The WG will work on the following items. Adding new work items will require rechartering. 1. Discovery of PEs participating in L2 service, and topology of required connectivity 2. Signaling of l2vpn related information for the purpose of setup and maintenance of l2vpn circuits. As much as possible PWE3 signaling procedures should be used 3. Solution documents (providing the framework for a specific solution, should include info on how discovery, signaling, and encaps work together, include security, AS as a separate document) 4. MIBs 5. L2VPN-specific OAM extensions--extensions to existing OAM solutions for VPLS, VPWS, and IP-only L2VPNs. Where necessary, the WG will coordinate its activities with IEEE 802.1 Goals and Milestones: Jul 03 Submit L2 requirements to IESG for publication as Informational RFC Jul 03 Submit L2 framework to IESG for publication as Informational RFC Jul 03 Identify VPLS and VPWS solutions for the WG Aug 03 Submit an I-D describing MIB for VPLS Aug 03 Submit an I-D describing MIB for VPWS Aug 03 Submit an I-D on OAM for VPLS Aug 03 Submit an I-D on OAM for VPWS Dec 03 Submit VPLS solution documents to IESG Dec 03 Submit VPWS solution documents to IESG Jan 04 Submit IP-only L2VPN solution documents to IESG Feb 04 Submit MIB for VPLS to IESG Feb 04 Submit MIB for VPWS to IESG Mar 04 Submit OAM for VPWS to IESG Mar 04 Submit OAM for VPLS to IESG Apr 04 Submit OAM for IP L2VPN to IESG
