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?????

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
