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:

2020-02-01T00:12:35.441721Z [N] «8» 0 BGP NOTIFY CEASE Peer-Deconfigured
2020-02-01T00:12:35.506884Z [N] «9» 0 BGP NOTIFY CEASE Administrative-Shutdown
2020-02-01T00:12:35.566658Z [N] «10» 0 Closed connection

After rebooting router starts with a clean routing configuration.
After that, it loads/commits configuration from /config/config.boot file.
It can be a cause, needs more tests.
It will be must impossible to get another behavior.
