Hello Pali,

Thank you for your answer.

I am aware RAs are supposed to be sent by routers. I attempted using dnsmasq 
for RAs, because it seemed easier than getting RAs to be sent from my VRRP 
address as source address.

I have enough information to proceed with dnsmasq configuration.

Met vriendelijke groeten,

Hello William! This is not possible as IPv6 gateway (router) address is
not present in RA packet structure. If client receives RA packet it
expects that sender of RA packet is gateway (router).

So if you do not have dnsmasq on your router, you must disable RA in
dnsmasq. And enable RA on your real IPv6 router.

In IPv6 network it is expected that RA is sent only by IPv6 router. RA
means Router Advertisement and only real router should advertise that is
