How to prohibit resetting bgp neighborship after any bgp config change in bird.conf
Hi, Using command '#birdc configure soft' from linux command line should not reset any peers. Thank you Budiwijaya On Fri, 7 Apr 2023 at 01:03, <saifullah@fiberathome.net> wrote:
Dear Forum, I am new in bird. I am getting a problem. When I am doing "service bird restart or reload" or "bird > configure" to affect any bgp config change, add, modification etc., then bgp neighborships are being reset. Is there any way to affect any configure change in bird.conf without resetting bgp neighborships?

Hello! If you change bgp protocol parameters or rename your config blocks, it will restart the sessions, no matter what. Most of the knobs need restarting the session anyway, even by RFC. The "configure soft" works only for filter changes and you should't run BIRD for a long time before actually reloading the affected channels. We may suggest better if you disclose what you are actually changing. Maria On 7 April 2023 14:00:34 CEST, saifullah@fiberathome.net wrote:

Hello, Right, thank you for your feedback. Actually if we modify (add/ delete/ change) any address-family then it will reset the corresponding BGP sessions with “birc> configure” or “service bird reload”. But if you restart the service by “service bird restart”, then it will restart all sessions. Seems it is normal behavior.

Hello! Well, of course all BGP sessions get reset when you restart BIRD itself. All the TCP sockets must be reconnected when the BIRD process starts anew. Or you may use the graceful restart feature to alleviate some of the restarting pain, anyway BIRD is supposed to run long-term so restart is needed only if you upgrade BIRD itself. The standard way to update the config is to reload it, not to restart BIRD. Maria On 8 April 2023 17:11:32 CEST, saifullah@fiberathome.net wrote:
