Hello,
the option you want to use is `graceful restart time <number>` as cited
from the documentation at
https://bird.network.cz/?get_doc&v=20&f=bird-6.html#bgp-graceful-restart-time:
|graceful restart time /number/|
The restart time is announced in the BGP Graceful Restart capability
and specifies how long the neighbor would wait for the BGP session
to re-establish after a restart before deleting stale routes.
Default: 120 seconds
And possibly these additional options:
|min graceful restart time /number/|
The lower bound for the graceful restart time to override the value
received in the BGP Graceful Restart capability announced by the
neighbor. Default: no lower bound.
|max graceful restart time /number/|
The upper bound for the graceful restart time to override the value
received in the BGP Graceful Restart capability announced by the
neighbor. Default: no upper bound.
Hope this helps!

Hello,
We use BIRD for communication with servers with higher-level switches.
In our config , there is config to set graceful restart like below.
protocol bgp example2 {
import all;
export all;
...
graceful restart on;
}
As far as I know, the default value for graceful restart is 120 seconds.
But I don't know how to change this time.
Please give me some advice on this. Thank you.
