Two CEASE notifications sent to BGP peers during reboot
Open, Requires assessmentPublicBUG

Description

On reboot of a VyOS router, I observed it sending the peer a CEASE (peer de-configured) followed ~60ms or so later by a CEASE (administrative shutdown). My understanding (which may be incorrect) is that only one CEASE should be sent.

As seen by a BGP peer (non-VyOS) at time of VyOS router reboot:
