Service types

The 7705 SAR-Hm series of routers offers the following types of services:

  • Virtual Leased Line (VLL) services

    • Ethernet VLL (Epipe)—a PWE3 Ethernet service over MPLS or GRE tunnels for Ethernet frames on 7705 SAR-Hm nodes.

  • BGP Virtual Private Wire Services (VPWS)

    • BGP VPWS is a point-to-point Layer 2 VPN service based on RFC 6624 (Layer 2 Virtual Private Networks using BGP for Auto-Discovery and Signaling) which in turn uses the BGP pseudowire signaling concepts from RFC 4761, Virtual Private LAN Services Using BGP for Auto-Discovery and Signaling.

  • Internet Enhanced Service (IES)

    • IES is a direct Internet access service where the SAP is assigned an IP interface for routed connectivity.

  • Virtual Private LAN Service (VPLS)

    • VPLS provides a Layer 2 multipoint VPN service to end customers. Sites in a VPLS instance appear to be on the same LAN regardless of their location. The 7705 SAR-Hm series nodes can participate in BGP VPLS-based services and traditional T-LDP signaled services.

  • Virtual Private Routed Network Service (VPRN)

    • VPRN provides a Layer 3 VPN service to end customers. VPRN services provide MP-BGP peering with other PEs, configurable QoS policy and filtering, and VRF import and export policies.

Pseudowire service types lists the supported pseudowire (PW) service types. The values are as defined in RFC 4446.
