Greetings all,
We're converting our 3Com router world to Cisco soon and I have a question
regarding the OSPF design. I'm including a link to a JPG in case anyone
wants to add their 2 cents. You can see it at:

This is a somewhat simplistic view of our network and the IP's aren't real,
but I'm hoping it makes sense regardless. We currently have a full T1 to a
frame cloud and our other 2 main buildings are off of that cloud as well,
one is 1M, the other is the balance of the T. Both of the remote sites are
pointing to the 1 PVC at our main site. My question is, would this OSPF
network work? I know the OBAZ, (One Big Area Zero - Wow! My first
acronym! - Hey Howard, feel free to use that one), is frowned upon, but
that's how my boss wants it, because that's how it is now. Not good logic,
but I have to follow orders sometimes.
A note: We have other sites off of the main site (Site 1) in another Frame
Cloud. It shouldn't affect what we're doing here, though.
Also, I didn't include the IPX networks on the Ethernet ports. That's not a
real issue right now.
Specifically, I'm unsure about using the Loopbacks. We're going to use them
for our DLSW (not pictured) links. What I'm unsure about is, can I use
these addresses, as given, with their masks, and distribute them via OSPF
and have it work?
If I'm completely off here, please feel free to let me know.
I'm including the proposed configs (snipped)
Thanks!
