[bird graceful restart time] Is there any way to set graceful restart time?

[David Petera]

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!
David
