Mark- You can use a route map to redistribute only the connected interfaces
that you wish:

redistribute connected subnets route-map muther

access-list 1 permit 173.168.40.0 0.0.0.255
route-map muther permit 10
 match ip address 1

and Lachlan is right about it redistributing everything that is showing up
as connected in the route table.

Hi Mark,
        I think the answer goes something like this. The 'redistribute' command
only works on what is in the route table. If you redistribute IGRP routes
then anything with an I next to it will get redistributed. The same applies
to connected routes. If it's in the route table with a 'C' next to it, it
will get redistributed regardless of what protocol is running on that
interface. HTH, feel free to let me know if I've missed the point
completely.
        Regards,
                Lachlan

Has anybody got any advice with respect to this one - see thread below:

The fundamental question is :

Does 'redistribute connected subnets' put E2 routes into OSPF even for
interfaces that are part of the OSPF process ?

Thanks

Mark
