Hi BIRD team and fellow BIRD users,
are there any plans to implement Graceful BGP session shutdown (https://tools.ietf.org/html/draft-ietf-grow-bgp-gshut) in future releases?
Ingress is pretty easy and only needs to be implemented once by the user: Check for BGP Community 65535:0 and set local pref to 0 on match
Egress is also simple, but more effortful. It also needs a config change in every maintenance window:
- Modify egress filter to add 65535:0
- Reload config and egress filter
BIRD could automate this by offering a command like "birdc disable bgp1 graceful 15"
which would send 65535:0 immediately and then disable the session after a configurable time, in this case 15 minutes.
What do you think?
