Subject: RE: OSPF for 400+ Locations
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!
