Can we see the configuration for the 2500 and 7500 (just the OSPF part).
Also, is this route in the table at all? That is, is another protocol

I think you got it wrong. 10^8 bites/second has cost 1. That means that

The classic case they are talking about is the Loopback address. Unless
you have "ip ospf network point-to-multipoint" Loopback address are

Hi,
Its nothing..its just that by default ospf advertises the loopback address
as a host route i.e with a mask of /32. This default behaviour can be
changed by giving the command ip ospf network point-to-multipoint under the
interface config mode.

You can not mix point-to-point and non-broadcast network types which is

Catherine,
You forget to define ospf network type in each frame interface.
Add this interface config command: ip ospf network point-to-point
Thank,

Hi John,
I'm busy preparing for the CCIE written. I came across a very good example
that is related to your problem in Routing TCP/IP Vol. 2 (Doyle) p.369. What
it comes down to is that you have a merger between 2 companies that are both
using the 10.0.0.0 network on their private networks - sound

Yep. You'll need a virtual-link between R1 and R2.

Are both side of the link on sub interfaces? Do you have anything configure
on the main interface or any unassigned DLCI's, which are automatically
assigned to the default interface?
With OSPF I tend to only inlcude networks to which the router is directly
attached, so in your case, network x.x.x
I hate to say what the problem appears to be.

Another good one!!
Could also add that Ospf timers need to be kept in mind if the hub is using
say for ex. a multipoint and the spoke a point-to-point and the task is NOT
to configure any #ip ospf network cmd. on the spokes

Hi,
Probably I should have asked some more questions -
Hello packet has the following important fields that should match on both
routers trying to form adjacency -
1. Network Mask,
2. Hello Interval,
3. Options field
4. Router dead interval
Make sure that the neighboring interfaces are of same netw
Hi and thanks for your reply. I had already attempted what you suggested
and still the adjacency does not come up.
Can you (or any list member) clarify for me whether the network command
along with the wildcard mask have to match exactly as the interface for
which you are enabling OSPF is configur

I was running 12.1.3 EA, I think it was on one of the routers. When I
switched it to 12.2.7 it seems to have come around. Has been holding routes
for several hours now. Make sense?

This sounds like a problem that was discussed here (or on the groupstudy
ccielab list) in the last few days. The problem then was EIGRP over ATM.
Now it's OSPF over ATM. Try specifying your OSPF neighbors manually, so
unicasting occurs.
There may be a better solution, but try this until someone
a comment or to in line ( like the states )
