Just to clarify, getting the connection established isn't a problem. No ppp
problems at all. From R2, I can ping the directly connected interface on R3.

R2 nor R3 can ping their own BRI interfaces. The configs are posted below.
They are "plain Jane"

It should work without PPP authentication. Post your config and lets have a
look.

Not necessarily stupid ;) I think I overheard someone saying that this is
the only way to get things working. I wouldn't do ISDN without it really.

I know this might sound stupid ; but I had to configure authentication when
i
use
dialer map
ppp authentication
