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…!!
Shahin..

hi shain u have done a very silly mistake

what is that

go through your router 2 confregation

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
r2config-if)=clock rate 64000*********(this term is missing)
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


if this type of problem occur then first you have to check
your clock rate becoz mismatc of clock rate is the one of
the main cause of such type of error there are more issue
due to which it occurs but you have tro know when you comes
in practical real senario
thanks
