Re: PPP problem

No, the problem doesn't have to do with a keepalive. The problem is
that R1 is going to install a /32 host route to R3 by default due to
the nature of IPCP on the PPP link. You can stop that from happening
on R1 with the "no peer neighbor-route" interface command, but then
you will not have a /32 at all and obviously it couldn't get put into
EIGRP.

I don't believe there is another option inherent to EIGRP. If you or
anybody finds one, I'd sure be interested to hear about it!
