[ixpmanager] Blackhole service on IXP manager route servers (RTBH)

[Behnam Yazdani]

Hello,

We want to implement RTBH service in our IX environment, currently we have activated IRRDB filtering. for this purpose we have deployed two Servers used as blackhole next-hop, they inject an ARP response to members that populate IX switches with BH-MAC, this BH-MAC is dropped on all IX switches. In our current deployment members will have to establish a new BGP session with a dedicated Blackhole Router. we want to integrate BH service with IXP manager route servers, however, there are two issue what we need to resolve for this purpose:
1) We need to change BH next-hop to the IP address of BH servers that their MAC is later dropped in IX switches’ CAM table, and I need to know how can we implement this in IXPmanager 
2) we need to change IRRDB filter so that generated prefix filters accepts /32 prefixes advertised by members, for example there’s a route object for 192.0.2.0/24 with AS65535 as origin. By default generated prefix-list will have /24 mask for AS65535 member, but we need  IXP manager  to generate prefix filter that accepts 192.0.2.0/24 Le 32 from AS65535
 
How should we configure IXP manager to resolve these two issues
P.S. we’re using bird as our route server

Thanks for your help
