 Description of Working Group:

 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--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--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.
 The group will review proposed protocol extensions for L2VPNs before 
 they are recommended to appropriate protocol-specific WGs.
 As a specific example, this WG will not define new encapsulation
 mechanism, but will use those defined in the PWE3 WG.

 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 service parameters

 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 and VPWS.

 6. Interworking of IP devices connected to an IP-only L2 VPN using
       dissimilar attachment circuits. This topic will be explored only
       after the basic L2VPN services (VPWS, VPLS, and IP L2VPN) are 
       defined.

 Where necessary, the WG will coordinate its activities with IEEE 802.1
