RFC 4664 – Framework for Layer 2 Virtual Private Networks (L2VPN), it describes the framework for L2VPNs (VPWS, VPLS and IPLS). 1AH, IEEE802. RFC 6074 Provisioning, Auto-Discovery, and Signaling in Layer 2 Virtual Private Networks (L2VPN) specifies that the NLRI encoding for BGP auto-discovery should be. These services include point-to-point Virtual Private Wire Service (VPWS) and multipoint Virtual Private LAN service (VPLS) that uses LDP and BGP signaled Pseudowires. • 6 VPE Service Note L2VPN-VPWS service on 3107 BGP PIC is supported from Cisco IOS XR Release 5. A Layer 2 VPN provides complete separation between the provider's network and the customer's network—that is, the PE devices and the CE devices do not exchange routing information. Types of L2VPN The types of L2VPN are distinguished by the characteristics of the service that they offer to the customers of the Service Provider (SP). The MPLS network adopts the LDP to distribute the L2VPN virtual circuit labels to realize the intercommunication between VPN A/Site1 connected to router 1 and VPN A/Site2 connected to router 3 (corresponding to VPN A), as well as the intercommunication between VPN B/Site1 connected to router 1 and VPN B/Site2 connected.
