Its working now!! you know what is the problem? You guys going to beat me :(

Let me example what i was doing. on my Router i have two interface.

1. 10.10.10.1/30   - Peer IP
2. 192.168.100.1/24  - Host Subnet

I was sending null route for 192.168.100.1/32 IP address which was
configured on router interface which BGP won't let you do null route..
:(

when i did 192.168.100.2 host IP address it works!! this is crazy.. :(

Sorry guys for trouble but its not documented anywhere you can't do
blackhole router interface IP. Just wonder what if attack send DDoS on
router IP address????
