First, Thanks everyone for your valuable input. Unfortunately, the Service
Provider I work for allows SE's to order hardware before I see requirements,
that is why no true redundancy exist in this network. I have decided to
create regional totally stubby areas and re-design IP scheme. My main
concerns were the 400 LSA databases and large routing table at host, this
design addresses these issues.

Hi Aaron,
So what have you decided for your design, I'm interested to know.
400 subinterfaces, thats one big config file =)

Thanks everyone! I think I have a game plan now. I feel more confident about
implementing OSPF in this scenario.
Thanks Again!

I am with you! I really want to do EIGRP but client is running Microsoft ISA
Server with OSPF routing. I know...I have to address that too. He also has
roughly 16 remotes already running OSPF on routers provider by another
provider other than me. The IP scheme is a mess too. If I blindly configured
OSPF I would have over 800 routes and 400 LSA databases at host. I am using
frame-relay point-to-point sub-interfaces, how would I assign different
remotes the same area without partitioning? If I purposely partitioned the
remote areas; is that just really bad design? I am just trying to find
someway to make this work and scale.
Thanks!
Aaron

If it's a bunch of small branch offices tied to a central office, and
every branch office is defaulted back to the central office which ties
into a 3745.
Well, how about an OSPF area for each region? If you do ten sites to a
region, that's only 40 areas. Instead of totally stubby, how about just
stubby. I don't think in modern networks you have to worry too much
about lsa's filling the pipes.
I don't have any real world experience with 400 sites of OSPF, but my
common sense would say, keep it simple.
BTW, Eigrp wouldn't even break a sweat over 400 sites. You could place
all offices into one eigrp as, turn off auto summary, and go get an
early lunch.
Are you doing the ip addressing of the sites at the same time?
Good time to take care of poor ip address planning is BEFORE you start
routing them.

Subject: OSPF for 400+ Locations
I have experience with OSPF but I am looking for suggestions on how to
implement OSPF in a Frame-Relay Hub/Spoke topology for 400+ locations.
Each
location only needs to know about the host through a default. My first
idea
is to have a separate area for each location and make it a totally
stubby
area. Is there a better way. My concern is that there will be 400+ areas
in
the OSPF Database at the host. The host will be a Cisco 3745. The
remotes
will all be Cisco 1751.
Thanks!
Aaron
