The standard uses "packet", the term "frame" is preferred because layer These messages are called both LCP packets and LCP frames while Link by sending special LCP messages across the physical link between Finally, the link is terminated using Terminate-Request and Terminate-Ack messages.

One Data message is shown being rejected due to an invalid Code field. In this example, an Echo-Request and Echo-Reply message are first used to test the link, followed by the sending and receiving of data by both devices. After subsequent exchanges using other PPP protocols to authenticate and configure one or more NCPs, the link enters the Link Open phase. Link Configuration is here shown as a simple exchange of a Configure-Request and Configure-Ack. This diagram provides an overview of many of the message exchanges performed by LCP during different phases of a PPP connection. Represents a summary of the LCP link, showing the different messageĮxchanges performed by LCP during these different life phases of a PPPįigure 26: PPP Link Control Protocol (LCP) Message Exchanges Link termination happens in the Link Termination phase. Link link maintenance occurs while the link is open, and of course, Is performed during the initial Link Establishment phase of a

Link Termination: The process of closingĪn existing link when it is no longer needed (or when the underlying.

There are three main stages of link life and LCP plays a Various life stages just as a biological organism does. The operation of a PPP link can be thought of as proceeding through As I discussed in the PPP fundamentals section, (in a way) the actions of other protocols.Ĭontrolling those links. LCP is the boss of PPP it is responsibleįor its overall successful operation, and for supervising The single most important protocol is the PPP Link Control Protocol Of all the different PPP suite protocols,
