When I put this back to eigrp, the same issue reocurred. Checking the eigrp toplogy table, before covergence shows the static learnt from eigrp, after the eigrp route is downed, and then restored, the route is no longer in the eigrp topology table, despite seeing the update in debuts. How can I trouble shoot..
