Background / Scenario
Frame Relay is a high-performance WAN protocol that operates at the physical and data link layers of the OSI
reference model. Unlike leased lines, Frame Relay requires only a single access circuit to the Frame Relay
provider to communicate with multiple sites that are connected to the same provider.
Frame Relay was one of the most extensively used WAN protocols, primarily because it was relatively
inexpensive compared to dedicated lines. In addition, configuring user equipment in a Frame Relay network is
fairly simple. With the advent of broadband services such as DSL and cable modem, GigaMAN (point-to-point
Ethernet service over fiber-optic cable), VPN, and Multiprotocol Label Switching (MPLS), Frame Relay has
become a less desirable solution for accessing the WAN. However, some rural areas do not have access to
these alternative solutions and still rely on Frame Relay for connectivity to the WAN.
In this lab, you will configure Frame Relay encapsulation on serial links. You will also configure a router to
simulate a Frame Relay switch. You will review Cisco standards and open standards that apply to Frame
Relay. You will also configure Frame Relay point-to-point subinterfaces
