I come to you because I wonder how to proceed to set up the blackhole on my network.
My forwarder (the only one), informed me that his BGP communities for the blackhole was 65535: 666, and that if I wanted to blackhole an IP to all their forwarders, I had to announce the blackholed IP (/ 32) with these communities.
How to proceed ?
I read on some topics that I should use the filters on mikrotik, but that means that I have to modify the "filter-out" of the peer as well?
Thanks in advance, if anyone can tell me :)
