What would be the advantages of using Point to Point Protocol (PPP) over High Level Data Link Control (HDLC) in this scenario?

Last Updated on August 7, 2021 by Admin 3

You are configuring a serial link between a Cisco router and a router produced by another vendor.

What would be the advantages of using Point to Point Protocol (PPP) over High Level Data Link Control (HDLC) in this scenario?

  • HDLC has a proprietary “type” field that may be incompatible with equipment from other vendors.
  • HDLC is not available on non-Cisco routers.
  • PPP is faster.
  • PPP performs error checking.
Explanation:
High Level Data Link Control (HDLC) has a proprietary “type” field that may be incompatible with equipment from other vendors. It is recommended that PPP always be used when combining equipment from multiple vendors because this Data Link layer WAN protocol is an industry standard. PPP is implemented in the same manner on all PPP-capable equipment.

HDLC is available on non-Cisco routers. However, the Cisco implementation has a “type” field that may prevent the connection from working.

PPP is not faster than HDLC.

PPP performs error checking, but so does HDLC.
