ou can think of LCP as the "negotiator" because it is responsible for negotiating these options between two routers.

PPP has two sublayers called network control protocol (NCP) and link control protocol (LCP).

NCP is responsible for supporting multiple Layer 3 protocols. Each protocol has its own NCP, such as the IPCP for IP communication and IPXCP for IPX communication. Think of NCP as the "packager," as it is responsible for packaging, or encapsulating, your packets into a control protocol that is readable by PPP.

The link control protocol is used for establishing the link and negotiating optional settings. These options include

• Compression - You can compress your data to conserve bandwidth across your wide-area network. Options for compression are Stacker and Predictor.
• Callback - With callback, you dial into a router using a modem or ISDN and then disconnect. The other router then calls you back at a predefined number. This option is used for centralized billing and security reasons.
• Multilink - Multilink allows you to bundle together more than one link to create more bandwidth. (Traffic will load balance across the links.) For example, you can bundle two 64K channels together to get a combined 128K.
• Authentication - You can use authentication to verify a router's identity when it is connecting into your router. Options for authentication include CHAP and PAP.

You can think of LCP as the "negotiator" because it is responsible for negotiating these options between two routers.

Its basically a method for encapsulating datagrams over serial links. PPP uses the High-Level Data Link Control (HDLC) protocol as a basis for encapsulating datagrams over point-to-point links

PPP Components

PPP provides a method for transmitting datagrams over serial point-to-point links. PPP contains three main components:

•A method for encapsulating datagrams over serial links. PPP uses the High-Level Data Link Control (HDLC) protocol as a basis for encapsulating datagrams over point-to-point links. (See Chapter 16, "Synchronous Data Link Control and Derivatives," for more information on HDLC.)

•An extensible LCP to establish, configure, and test the data link connection.

•A family of NCPs for establishing and configuring different network layer protocols. PPP is designed to allow the simultaneous use of multiple network layer protocols.
