I am trying to do ppp over frame and having the hub (R1) authenticate
the remotes (R2 and R3). I would like to get R2 to use chap, and R3 to
use pap. Chap works great, but I cannot get pap to work on R3. If I
change R3 to chap, then it all works. It appears that the
authentication on R1, where it should skip to pap after not getting chap
info from R3 is not functioning. Actually, I am not sure that this is
even possible. Thoughts?

R1.......

username Router3 password 0 cisco
