Thanx for the solution,
I forgot to say that this is production scenario, hence I can not reconfigure all the neighbor statement for the solution. Also there are many other routes are being announced to these neighbors which are not subjected to the conditional bgp announcement.
Any other solution that does not reconfigures the neighbor ??
