How to prohibit resetting bgp neighborship after any bgp config change in bird.conf

[saifullah at fiberathome.net]

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. 

 

Thanks

Saifullah

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.

Hi,

 

Using command '#birdc configure soft' from linux command line should not reset any peers.

 

Thank you

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?
