You can have ppp authentication under the BRI interface or the dialer
interface. It just depends on how customized you want your config. Many
people think you need to have both and you dont. If you only have 2 routers
talking isdn to each other then you can specify any ppp authentication
cammands under the BRI interface.
If you have multiple authentication types or isdn connections, then use the
dialer interfaces for different authentication types and callbacks...
