Sorry - that should be
sysctl -w net.ipv6.conf.all.accept_ra=0
to disable that, not 1.

Try:
sysctl -w net.ipv6.conf.all.accept_ra=1
to persist between boots, be sure to add this to your /etc/sysctl.conf file.
This should prevent the box from listening to any RA announcements.

But I am still getting a global IPv6 (and of course local scope).
What else do I need to do to disable the listening for RA
announcements
and setting an IPv6 global address? I do not want to reboot the box.
There are other modules, most notably bonding that rely on the ipv6 module being loaded. What I do is place "options ipv6 disable=1" in "/etc/modprobe.d/ipv6.conf". That does require a reboot, which I know
you
are looking to avoid, so you may want to try other methods to remove
your
address in the running configuration.
'All' I need is for the system not to have a global IPv6 address. Then
it
will not try to connect to other global IPv6 systems which will reject
the
connection, as the IPv6 rDNS cannot be set, given it is a dynamic IPv6 assigned address from the ISP.
I tried:
# cat /etc/sysconfig/network NETWORKING=yes HOSTNAME=z9m9z.htt-consult.com NETWORKING_IPV6=no IPV6INIT=no
and 'service network restart' but still showing IPv6 addressing.
I would try adding the below line to /etc/sysconfig/network.
IPV6_AUTOCONF=no
