I am using a separate IPv6 interface (6in4 tunnel) for outbound ipv6 traffic. Is there a way to set up a tracker to remove the IPv6 static route if the link loses connectivity (tunnel endpoint not working). Right now if the tunnel goes down, computers still try to use IPv6 and traffic just get blackholed…
Is there a way to let the computers fall back to IPv4 in case of IPv6 failure in a matter of seconds? At least respond with something like destination unreachable instead of just timeout…
