Hello,
I'm having some routing difficulty with point-to-point
interfaces. The main ATM interface has no ip address
assigned to it, only the subinterfaces have
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
the neighbor command. I'm unclear as to what interface should
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
directly connected.
Thanks for any help.
Ken
