I would venture to say that if you did a "show ip bgp x.x.x.x" before
the routes flip to IGP, that the next hop would be marked as
inaccessible. Have or can you verify this? It's possible you have a next
hop recursion problem causing the routes to be installed and removed by
the scanner process when the next hop is marked inaccessible.
