About ISDN config

[davidliji]

customer asked for user-defined username instead of the default hostname of the router to configure two router connected by ISDN, generally, we configured router like:

RA(1.1.1.1)------(1.1.1.2)RB

-----

hostname RA

username RB pass xx

int bri0

dialer map ip 1.1.1.2 name RB b xxxx

-------

hostname RB

username RA pass xx

int bri0

dialer map ip 1.1.1.2 name RA b xxxx

but customer required implement another username, how can I do?

Thanks.

With CHAP, configure "ppp chap hostname xxx" under the bri interface, where xxx is the alternate username you want to use.

With PAP, you can use "ppp pap sent-username xxx password yyy"

Hope this helps,

[davidliji]

could you give me a complete configure?

thanks
