Sorry I wasn't clear on that. Traditionally on a hardware, e.g. cisco/brocade, router performing the RTBH role, I'd add blackhole routes by way of static routes with a particular tag; one tag for block this source, one tag for block this destination. Redistribute static would let route maps operate against those tags to turn into bgp communities being applied to the announcements, and then the real routers can do what they need to do. When I tried out Quagga/Zebra as an alternative, it doesn't work this way, so while it was nice that it could pick up static routes from the OS, or have them added manually just like a hardware router, there was no concept of the route tag getting to Zebra for it to do the rest of the work on the BGP side. I'll check out Bird too; thanks. On Wed, Jul 1, 2015 at 3:41 PM, Job Snijders <job () instituut net> wrote:

It is one of the most beautiful open source BGP speakers: http://bird.network.cz/ BIRD does not have anything like an restful API, but you can just generate the config file and reload it on the fly to accomplish the same. Can you elaborate on what you mean with 'tags'? Could you use BGP communities instead? Kind regards, Job
