>From what I can see, this is a problem with the debian/ubuntu packaging of quagga rather than quagga or any of the quagga daemons.

On Debian/Ubuntu there is only a single /etc/init.d/quagga script which does everything, and the stop section has this line:

>    ip route flush proto zebra

Which is called regardless of which daemons you are stopping. (So this would also remove BGP routes...)

On the other hand, the Redhat packages contain separate scripts for each daemon (/etc/init.d/bgpd, /etc/init.d/zebra ... /etc/init.d/ospf6d) and only the zebra script has the "ip route flush" line.

I don't recall the quagga repo containing a debian directory, so I believe this is packaged externally by someone from debian so you would need to contact them.
