Ohh, I see. > GW A GW B > 2001:db8:2::1/48 2001:db8:1::1/48 > | | > --your-hosts-on-your-network-- > I actually have a setup similar to that at home, with 2 tunnnel providers and 1 router which acts like 2 gateways, it sends 2 RA/prefixes. But it is more like failover setup, when one tunnel is down, it stops sending the RA for that prefix. I have it set to expire very quickly.
