[Dnsmasq-discuss] dnsmasq doesn't send RA

[John Gorkos]

This sounds remarkably similar to the problem I described here:
http://lists.thekelleys.org.uk/pipermail/dnsmasq-discuss/2013q4/007810.html
Mine is on a Debian system, but the symptoms are the same.

I never did find a solution.  I simply run radvd in parallel with dnsmasq.
