The man page seemed to suggest that the defaults should work:

  # rtadvctl -v show
rl0: flags=<UP,CONFIGURED,PERSIST> status=<RA_SEND> mtu 1500
         DefaultLifetime: 30m
         MinAdvInterval/MaxAdvInterval: 3m20s/10m

         ReachableTime: 0s, RetransTimer: 0s, CurHopLimit: 64
         AdvIfPrefixes: yes
         Next RA send: Mon Aug 27 18:24:48 2012
         Last RA sent: Mon Aug 27 18:17:28 2012
