Hi Guys
I am facing one problem while configuring PAP over Point to
Point links. Configuration scenario is like this.
ROUTER 1: (Hostname – R1)
R1(config)#username R2 password CCNA2
R1(config)#interface serial 1/1
R1(config-if)ip address 10.0.0.1 255.0.0.0
R1(config-if)#lock rate 64000
R1(config-if)#encapsulation ppp
R1(config-if)#ppp authentication pap
R1(config-if)#ppp pap sent –username R1 password CCNA1
R1(config-if)#no shutdown


ROUTER 2: (Hostname – R2)
R2(config)#usename R1 password CCNA1
R2(config)#interface serial 1/1
R2(config-if)#ip address 10.0.0.2 255.0.0.0
R2(config-if)#encapsulation ppp
R2(config-if)# ppp authentication pap
R2(config-if)# ppp pap sent –username R2 password CCNA2
R2(config-if)#no shutdown

Now problem is that, after configure the command “ppp
authentication pap” the “Line protocol” status goes down on
each router. But when I disable this command using “no ppp
authentication pap”, the “Line Protocol” status goes up.

What could be the problem, can anyone explain it plzzz….!!!

Thanks in Advance…!!

ok... Jitu.. I m agree with u.. but we have to configure
clock rate only on DCE router... M i ryt?????? There is no
need to configure clock rate on DTE router, as it
synchronise according to DCE router.


i got this concept somewhere in books & i also tried this
in PACKET TRACER. I also saw the line status & protocol
status. All are in up state, when i configured clock rate
on DCE & i left DTE.

U cn try this on packet tracer.


Let me know.. Is it correct or wrong?????
