Group,
I am trying to setup ISDN connection with chap authentication without
user database definition. Following is the config and deb ppp authen, I've
omitted the unnecessary part, the router can dialup successfully without
chap authentication, when I put chap on, I got error message that "Username
R2 not found", since R1 use default password why it still asking username
R2?
I tried this on both version 12.1.17 and 12.1.5T10, same result.
Any ideas ? Thanks in advance.
Frank
