Frame Relay Technology

Frame Relay (FR) is a high-performance WAN protocol. It is a packet switching protocol that operates at the physical and data link layers of the OSI reference model. It is cost effective, involves less investment, is reliable and provides guaranteed bandwidth at any given time (CIR - Committed information rate).

Frame Relay interface types - Part 3 (Subinterface - Point-to-Point)

We will wrap up this series configuring frame relay sub interface point-to-point for the third subnet 100.100.120.0/29. Refer the fig 1.3 below.

Frame Relay interface types - Part 1 (Physical Interface)

There are several interface types on frame-relay, according on how you configure your serial interface and on what is the purpose you will achieve.

1. physical interface
2. subinterface multipoint
3. subinterface point-to-point

Lets talk about each of them.
