yeah, this is annoying.  I use the following:

--
net.ipv6.conf.default.autoconf = 0
net.ipv6.conf.default.accept_ra = 0
net.ipv6.conf.default.accept_ra_defrtr = 0
net.ipv6.conf.default.accept_ra_rtr_pref = 0
net.ipv6.conf.default.accept_ra_pinfo = 0
net.ipv6.conf.default.accept_source_route = 0
net.ipv6.conf.default.accept_redirects = 0
net.ipv6.conf.default.forwarding = 0
net.ipv6.conf.all.autoconf = 0
net.ipv6.conf.all.accept_ra = 0
net.ipv6.conf.all.accept_ra_defrtr = 0
net.ipv6.conf.all.accept_ra_rtr_pref = 0
net.ipv6.conf.all.accept_ra_pinfo = 0
net.ipv6.conf.all.accept_source_route = 0
net.ipv6.conf.all.accept_redirects = 0
net.ipv6.conf.all.forwarding = 0
--

No doubt a pile of this is redundant, but it does what I want and it is as
easy to push 15 lines of config to all servers as it is to push 2.
