Hello,
For those interested to the solution to this problem, take a look
at this link.

You want to look at the section, Mapping a protocol address to a PVC.
I guess just like in Frame-Relay, you need to setup a mapping mechanism
to associate the PVCs to an IP address within ATM.
Regards Ken

> Hello,

> I'm having some routing difficulty with point-to-point

> IP addresses assigned to them. Because of that, there are
> no interfaces on the 192.168.20.0 network that are broadcast.
> I understand that with IGRP over NBMA networks, you must use

> be used with the neighbor command. I can't create a loopback
> interface and assign anything on 192.168.20 because of the
> limitation of two host addresses on point-to-point networks.
> I can not ping from the 3640 to the 7206 even though it is
