Hello group, I'm running BIRD on FreeBSD and I came across a problem with overriding static routes created outside of BIRD. The situation is that for installation of the operating system (contacting repositories, Puppet and some other services) system needs to have a static default gateway but once the system is fully installed it runs BIRD and talks BGP to core routers. Default routes are created with the usual FreeBSD method: [9:08:14] hwlb-awtest-01 ~/ # cat /etc/rc.conf.d/routing defaultrouter="1.2.3.4" ipv6_defaultrouter="a::f" Routes are created with UGS flags: [9:11:17] hwlb-awtest-01 ~/ # netstat -rn | grep default default 1.2.3.4 UGS public default a::f UGS public Once BIRD is started the log gets full of those messages: Jun 15 08:57:32 hwlb-awtest-01.ndco.ig.local bird[2216] KRT: Error sending route 0.0.0.0/0 to kernel: File exists Jun 15 08:57:50 hwlb-awtest-01.ndco.ig.local bird6[2213] KRT: Error sending route ::/0 to kernel: File exists I've looked at BIRD's source and I understand that BIRD replaces routes using krt_replace_rte and krt_send_route, and that all routes managed by BIRD have RTF_UP | RTF_PROTO1 flags. Those are not the flags created by `route add` on FreeBSD by default. However if I make default routes with those flags via `route add default 1.2.3.4 -proto1 -nostatic`, BIRD will happily replace them. Kernel protocol is configured with "learn" option. Is this a bug? Or should I just adjust the static routes to be BIRD-compatible? -- | pozdrawiam / greetings | Powered by macOS, Debian and FreeBSD | | Kajetan Staszkiewicz | www: http://vegeta.tuxpowered.net | `------------------------^--------------------------------------'
