The configurations for the routers would be nice to see. Also the
output of a show interface from both routers and lastly an output of
each router's routing tables would help. Without this information
your
replies will be pretty much just a guess and one may even be the
right
guess ;-) For example it could be an access list issue, IPCP isn't
"open", routing problem, etc but who knows without more information.
As a side note when I taught a CCIE class with Paul Borghese years
ago
we told the students that they could never tell us that they "can't
ping". We told them that they must give us more details about their
problem before we would help them. We said that the "I can't ping"
students are in the CCNA level classes and not the CCIE level classes
;-)

Subject: ppp connections
Hello:
I just built a link using ppp over a directly connected serial
link.This
link is up / up.I am unable to ping my directly connected neighbor.
Is
this explainable?I know i've pinged my neighbor before but now, I
can't.
Can somebody please advise me on this delima? Thank you kindly.
PS
I do see the peer neighbor route and i have a rip connection over
this
link.
Thank you again.
