Can't find the original post so replying and agreeing with Les.  Have the
same ongoing problem with radvd.  When My IPv6 tunnel provider burps, the
tunnel drops.  The tunnel daemon usually reconnects but radvd stays down. 
Solution:

*/12 * * * * /sbin/service radvd status > /dev/null 2>&1 || /sbin/service
radvd start 2>&1

in crontab.  How hard is that?  And without all of the systemd nonsense.

Cheers,
Dave
