Hi Kym,
If the connected interface that you are talking about is not in area 0 , you
may still use area range command on the other side of the link. OR You can
do redis connected and use summary address. It works up to IOS 12.0.
I found problem when I used the same command on IOS 12.1. It does not
redistribute the connected interface if the interface is already in any of
the ospf area. It works for any interface which are not in any routing
process. Try by using secondary address to overcome this problem.
Any one has better solution please add.
Regards,
Ravi
