I fixed this by adding
Username R5 password 0 CISCO
Int bri0/0
Ppp authentication chap.
If only
Ppp chap password 0 CISCO command is applied.
I'm not exactly sure if this was suppose to be able to ping at this stage.

Hi,
Try debugging ppp authentication to see the errors. Suggest adding username
R5 password 0 CISCO on R4 to see if that helps.
Also somewhat curious why you have ppp authentication chap on R5 but not on
R4 and then on R4 you have ppp chap password but not on R5. I don't have
the lab in front of me so perhaps you are trying something specific to that
scenario.
Thanks,
Ian

Going thru Lab 3 and I've set up PPP authentication between R4 and R5 as the
tasks specify. However at this point
I can no longer ping from r5 to r4 I see the matches on the access-lists.
But ping isn't responding as previously on the last tasks. Has anyone else
run into this ???
