Hello Baljit,

you have already found the major difference PPP has an architected field to tell what is the upper layer protocol it supports.

Other differences exist:

PPP support authentication and has an advanced link negotiation.

PPP supports multilink PPP for link aggregation.

So you understand that PPP is not only a multiprotocol version of HDLC

Hope to help

Giuseppe
