I don't think it is possible to have GR only for upgrades. It would need to reverse the logic: sending a BGP cease message "upgrade in progress" to let the other end know they should keep the routes. Maybe something could be done with a community similar to the graceful session shutdown but with a timer associated.
Hi Currently there is RFC 8538 that adds soft-reset notification messages triggering BGP graceful restart, but i don't think it allows disabling unplanned GR. So that would likely require another draft. -- Elen sila lumenn' omentielvo Ondrej 'Santiago' Zajicek (email: santiago@crfreenet.org) OpenPGP encrypted e-mails preferred (KeyID 0x11DEADC3, wwwkeys.pgp.net) "To err is human -- to blame it on a computer is even more so."
