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.

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