ICMPv6 RA: ndisc_router_discovery() failed to add default route

[John Bage]

I have the rv215w and have it setup on our network. I have downloaded and installed the latest firmware prior to putting the router in place. The issue I have though ius I keep getting "ICMPv6 RA: ndisc_router_discovery() failed to add default route" repeatedly in the logs. I have it set to dhcp and not sure what I need to do to resolve this issue.

I have the same issue.  In my case, as I posted here, IPv6 only seems to work on the main VLAN, but not on the other(s).  I wonder if this "ICMPv6 RA" error is referring to the default route that fails to install on the extra VLAN(s), but of course I am not exactly sure.

Had the same issue and resolved it by making sure the default gateway was set correctly. My gateway was set to a link-local address.

#route -A inet6
