about lcp
Line 4:
* searches for errors in configuration
* can terminate the link if requirements exceed the parameters
Devices cannot use PPP to transmit data over a network until the LCP packet determines the acceptability of the link, but LCP packets are embedded into PPP packets and therefore a basic PPP conection has to be stablished before LCP can reconfigure it.
The LCP over PPP packets have control code 0xC021 and their info field contains the LCP packet, which has four fields. (Code, Id, Length, Data)
* Code: Operation requested: configure link, terminate link, ... and acknowledge and deny codes.
* data: Parameters for the operation
