I cannot answer this question. > I'm using it now on a large IXP peer, rather than a specific route > filter, since their route list would be far too long. > > I'm thinking that the route limit option is almost like having no > limit at all, so maybe I can just remove it and fully trust the ISP > (HE.net at MBIX) BIRD is one of the few routing engines that performs exceptionally well with very large prefix filters. Don't be afraid to deploy large prefix filters when using BIRD! :-) A tool like https://github.com/snar/bgpq3 uses IRR data to generate prefix filters for BIRD, XR, IOS, Junos or JSON format. When I generate a filter with 'bgpq3 -A -b AS-HURRICANE > /opt/as6939.ipv4.conf' it generates a 2.7 megabyte file which you can include in your main bird configuration. Hope this helps. Kind regards, Job ps. Don't forget the sysctl advise from the bgpq3 manual
