virtual private network identifier (VPN-ID)

A globally significant VPN identifier.

virtual router (VR)

An abstract object managed by the Virtual

Router Redundancy Protocol (VRRP) that acts

as a default router for hosts on a shared LAN.

virtual router forwarding (VRF)

Provides traffic isolation between the customers

operating over the same node. Each virtual

router emulates the behavior of a dedicated

hardware router by providing separate routing

functionality, and the network treats each VRF as

a separate physical router.

Virtual Router Redundancy Protocol (VRRP)

A protocol used in static routing configurations,

typically at the edge of the network. This protocol

operates on multiple routers on an IP subnet

and elects a primary gateway router. When the

primary router fails, a backup router is quickly

available to take its place.

Voice over IP (VOIP)

The technology that delivers voice information

in digital form in discrete packets using the

Internet Protocol (IP) rather than the traditional

circuit-committed protocols of the public switched

telephone network (PSTN).
