point to point protocol and hdlc protocol

first of all we will take two router.and will assign an ip address to them .after giving ip address connect router to  wire In the router to connect the wire to us the physical device view  will be openend in the router after connecting to the serial port , we had to give IP in the router must provide the host name before giving the IP address after giving a host name and IP address then create user name and password will be given to router  then the next command will be in capsulation after this command then the next command will be the ppp authentication

similarly in the second router we have to do this thing in this way both router will be connected to each other  -some step are in how connect two router point to point and HDLC

first step -assign ip address in router

*  connect wire only serial dCE

* then open router and go it the physical divice view and change the setting

*after that assign router host name

* then some important step

#username r2 password ccnna   …….. any one password

#int se0/0/1   any one serial port

#encapsulation ppp

#ppp authentication chap
