Description of Working Group:
Alex is the routing advisor.
Russ 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
