Hi, In the release notes for Bird 1.5.0, it's noted that the 'route limit' configuration is deprecated. Is there another command I should use instead? Is there a reason why this option is a bad idea to use? 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) Thanks, -- Jonathan

Yes, 'import limit X action restart' works the same way.

It is a BGP-specific option introduced before generic import/export limits. -- Elen sila lumenn' omentielvo Ondrej 'Santiago' Zajicek (email: santiago@crfreenet.org) OpenPGP encrypted e-mails preferred (KeyID 0x11DEADC3, wwwkeys.pgp.net) "To err is human -- to blame it on a computer is even more so."

I cannot answer this question.

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
