block, traffic using bgp

RouterOS Forwarding Protocols
1

Hello

We have server that sends to mikrotik via BGP /32 announces with special community.

We want to block traffic from and to the announced IP.
For now we succeed with blocking of incoming traffic with:

add action=accept bgp-communities=XXXXX:666 chain=from-anti-ddos prefix-length=32 set-type=blackhole

But how to block outgoing traffic? (better without using firewall - we’re in fast path)

Here is a nice discussion and with how to info ..
