Hello everyone,

Today, I will share with you the stages that PPP goes through from physical up to line protocol up. 

PPP has to go through the following phases before it enters the Line Protocol Up phase from the Physical Up phase:

  • LCP negotiation, during which the Maximum Transmission Unit (MTU), magic number, authentication mode, and asynchronous character mapping are negotiated

  • Authentication in either CHAP or PAP mode

  • Network layer negotiation including IPCP and IPXCP

A negotiation failure at any phase will terminate link establishment.

That is all I want to share with you! Thank you!
