This document summarizes VPN and Frame Relay networking concepts. It discusses how site-to-site and remote-access VPNs provide secure connections, and how PPP supports authentication over asynchronous and synchronous links. Frame Relay interfaces are either point-to-point or multipoint, and commands like show frame relay lmi, show frame relay pvc, and show frame relay map can be used to troubleshoot Frame Relay connections.
