What happened to our PPP negotiation? Remember our LCP, IPCP, and CDPCP phases? Yeah…they are not here anymore. Obviously a PPP problem, even though we can hardly “see” a PPP problem so we need to go back and check our PPP encapsulation. kissane#sh int bri0/0 BRI0/0 is up, line protocol is up (spoofing) Hardware is PQUICC BRI with U interface Internet address is 192.168.1.2/24 MTU 1500 bytes, BW 64 Kbit, DLY 20000 usec, rely 255/255, load 1/255 Encapsulation HDLC, loopback not set Got it!
