Hi, when you use a prefix-list to filter out a prefix in a BGP neighbor
relationship, you always must to do a hard reset, soft reset or Route
refresh on the local router, because the routing information on the
other peer is saved on the BGP table, and it need to be updated with the
new policy. When you enter Clear ip Route * on the remote peer without a
reset, you only clear the Global IP routing table and the router still
have the prefix on the BGP Table.

I dont think it should behave the way it is happening wid u. I'll
configure
this in my lab and revert back.
Till then can You please post your config......
also, check "sh ip bgp neigh x.x.x.x received-routes" on destination
router.
