Dan,

Here is a working config from my lab for one-way chap, with callback server,
and a unique user name which I think are the three request I always see
people ask for on this list. Use debug ppp authentication on both routers to
see the authentication difference when using the "callin" parameter.

Callback Server:

!
hostname R3
!
username user7
!
isdn switch-type basic-ni
!

interface BRI0
 ip address 2.2.2.1 255.255.255.252
 encapsulation ppp
 dialer map ip 2.2.2.2 name R5 class callback broadcast 8358662
 isdn switch-type basic-ni
 isdn spid1 0835866101
 ppp callback accept
 ppp authentication chap
 ppp multilink

!
map-class dialer callback
 dialer callback-server username

============================================================================

Callback Client:

!
hostname R5
!
username R3
!
isdn switch-type basic-ni
!

interface BRI0
 ip address 2.2.2.2 255.255.255.252

 ip ospf demand-circuit
 dialer idle-timeout 30

Subject: PPP Authentication one way.

Can anyone give me the difinitive answer on how to set this up?

I have seen many things in practice labs & on this board, but I want to
know the proper way.

One side never authenticates, but dialer maps need to be placed on both
sides.

Thanks,
