Hi:

What about this:

router ospf 10
  ...
   default-information originate route-map no_exist128

  route-map no_exist128 deny 10
   match ip address 1
  route-map no_exist128 permit 20

    access-list 1 permit 128.10.1.0 255.255.255.0

Hello,

To me this sounds like conditional advertising that
can be done with BGP.

I do not see how one can do this, I do not know of any
Cisco tweak with conditional advertising on OSPF.

I would be enligtened to know if you received a
response detailing how this is possible.

rgds,
Sage
