An Ethernet link supports a number of data link protocols. These remote facilities might be a mile apart or they might be hundreds of miles apart. Most of these technologies are covered in more advanced courses such as CCNP. Title. Synchronous WAN links require the CSU/DSUs on each end of the link to operate at the exact same speed. What is HDLC? In comparison with other WAN protocol it creates very little overhead. It also negotiates other WAN options that are handled by the NCPs. By Imad Daou Leave a Comment.

The protocols they use for to talk to each other, routing protocols, should not be confused with ROUTED protocols like IP and IPX that carry data on the network. Common routing protocols include RIP, RIPv2, IGRP, EIGRP, IS-IS and BGP. Frame Relay is another L2 Protocol. There are more than one ways to build wide-area networks employing various types of connections, technologies, and devices. There are several WAN Protocols that are used between different locations of different networks. CCNA Routing and Switching << IP and Network Fundamentals Course >> Models, Protocols, and Standards Section. + High-Level Data-Link Control (HDLC): a point-to-point protocol and it is the default WAN protocol … PPP can be used as the data link layer protocol and frame for the following types of point-to-point, serial, synchronous and asynchronous network connections: Dial-Up, ISDN, Leased Line (e.g. Home; Study Guides. This allows you to practice all WAN protocols that you will encounter in CCNA R&S. common terms and acronyms. * PPP enables the ISP to assign an IP address to the customer WAN interface. 40.
