Differences between HDLC and PPP are
HDLC
HDLC - High level data link control used in conjunction with Networking protocols like PPP (point-to-point) protocol. According to RFC 1662, PPP uses HDLC like frame by providing address and control fields. For PPP these fields are constants 0xFF and 0x03.

PPP (Point-to-Point Protocol) has several advantages over HDLC (High-Level Data Link Control) for serial communications, primarily its support for multiple network layer protocols, allowing for more flexible and versatile connections. Additionally, PPP includes built-in mechanisms for authentication, error detection, and link quality monitoring, enhancing security and reliability. Its ability to negotiate link parameters dynamically also enables better configuration during connection establishment compared to HDLC's more rigid structure.
They cannot communicate.
1. Frame Relay 2. HDLC 3. PPP
there may be the issue with the layer 2 protocol like hdlc or ppp is not configured or wrongly configured if the interface is serial interface.
Which is the most common encapsulation in use on BRI Interface ? A. SDLC B. ATN C. HDLC D. PPP
The most common WAN data-link protocols are: 1. HDLC 2. PPP 3. Frame Relay 4. ATM
Data link layer protocols like PPP and HDLC define how data is encapsulated for transmission across a WAN link.
Serial interfaces do not pass any MAC information because the information is formed using WAN encapsulation (PPP. HDLC, Frame Relay).
