Router#show interfaces serial 0/0/0

Serial0/0/0 is up, line protocol is up (connected)

Hardware is HD64570

Internet address is 20.0.0.1/8

MTU 1500 bytes, BW 64 Kbit, DLY 20000 usec, rely 255/255, load 1/255

Encapsulation HDLC, loopback not set, keepalive set (10 sec)

    [output is omited]



Router#configure terminal

Router(config)#interface serial 0/0/0

Router(config-if)#encapsulation ppp

Router(config)#exit

Router#show interfaces serial 0/0/0

Serial0/0/0 is up, line protocol is down (disabled)

Protocols is disable.
To enable it set the encapsulation back to HDLC and restart the port with shut down command

Router#configure terminal

Router(config)#interface serial 0/0/0

Router(config-if)#encapsulation hdlc

Router(config-if)#shutdown

Router(config-if)#no shutdown

Router(config-if)#exit

Router(config)#exit

Configuration of PPP

Now we will configure PPP encapsulations on both router. We will also authenticate it with CHAP. Hostname of Router are R1 and R2 and password is lp2m.
Double Click on R1 and configure it

Router>enable

Router#configure terminal

Router(config)#hostname R1

R1(config)#username R2 password lp2m

R1(config)#interface serial 0/0/0

R1(config-if)#encapsulation ppp

R1(config-if)#ppp authentication chap

R1(config-if)#exit

R1(config)#

Now configure R2 for PPP

Router>enable

Router#configure terminal

Router(config)#hostname R2

R2(config)#username R1 password lp2m

R2(config)#interface serial 0/0/0

R2(config-if)#encapsulation ppp

R2(config-if)#ppp authentication chap

R2(config-if)#exit

%LINEPROTO-5-UPDOWN: Line protocol on Interface Serial0/0/0,
