6. Frame Relay Components
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. #systemengineer7131 #CCNA #CiscoNetworking #WAN #NetworkingTutorial #CCNABoost #CiscoRouter #CCNA2026
