Thanks Andy I actually tweek the distance under the ospf process and it
worked but one of the routers is in eigrp. I tried doing the same it didn't
work so i had to tweek the admin distance of all mu external routes in eigrp
to be greater than 200. And that worked. I won't mind if there is a better
solution than that.
Thanks,
