Hi

I have 2 routers 7206 & 1841 connected point-to-point and wanna prove if pap and chap is working. when I configure pap on either router my serial goes down, below are my configs for both routers.

R1

!

interface Serial0/1/0

bandwidth 2000000

ip address 165.148.120.1 255.255.255.252

encapsulation ppp

no keepalive

clock rate 8000000

ppp authentication pap

ppp pap sent-username mpho password 0 mpho

!

R2

interface Serial6/0

bandwidth 2000000

ip address 165.148.120.2 255.255.255.252

Hello Lawrence,

I don't think you can use pap and Chap together is not a good advice to try to use both. Stick to one and make sure your password are correct,it is case sensitive.

I only used one and that is PAP, but still my interface is protocol went down. Is there a problem with my configs?

Okay,

Check the Clock rate.

Hi

If you look at the out of

show interface Serialx/x

you will probably see the LCP status as TERMsent or if you debug ppp auth you will see it failiing.

Have you created the username and password in the routers with the command

username mpho password mpho

This is needed on both sides.

Thanks, your solution worked.
