Get a solid foundation in Frame Relay — one of the classic WAN technologies you need to know for the CCNA exam!
In this video, you'll learn:
- What Frame Relay is and how it differs from other WAN technologies
- Key Frame Relay components: DTE, DCE, and Frame Relay switches
- What a Virtual Circuit (VC) is — PVC vs SVC
- How DLCI (Data Link Connection Identifier) works
- The role of the Local Management Interface (LMI)
- How Frame Relay maps Layer 3 addresses to DLCIs
- Committed Information Rate (CIR) and how bandwidth is managed
Frame Relay may be legacy technology, but it remains a tested topic on the CCNA exam. Understanding its components builds the foundation for everything else — configuration, troubleshooting, and subinterfaces.
