How does PPP interface with different network layer protocols?

  • by using separate NCPs
  • by encoding the information field in the PPP frame
  • by specifying the protocol during link establishment through LCP
  • by negotiating with the network layer handler

Explanation: PPP can support multiple network layer protocols, such as IPv4, IPv6, IPX, and AppleTalk. It handles the interface with various network layer protocols via separate NCPs. There is a protocol field in a PPP frame to specify the network layer protocol that is being used. The information field in a PPP frame is the data payload. LCP sets up and terminates a link. It does not check which network layer protocol is used for the data.
