Routers are often used to build wide-area networks, and the footprints of WAN links are very different from those on Ethernet. Common WAN packages are HDLC, PPP, Frame-relay, etc., and this chapter describes HDLC and PPP. PPP, in contrast, has more functions than HDLC.1.1.1 HDLC IntroductionHDLC is a frame-wrapping format on a point-to-page serial line with a very different frame format from the Ethernet frame format, and HDLC has no source Mac and destination MAC addresses.
