Re: Who can use ipv6 normally?

Hey. Unfortunately, ROS used to use IPv6 RA only to advertise DNS servers for IPv6 hosts. DHCPv6 not working as I know. Win 10 doesn't understand IPv6 RA to grab DNS dynamically. So, you should just write them by hand.

Re: IPv6 accept-ra bug

I have a few RB951G's which act as APs/bridges (not routers).

Of ourse it can. it's all about administrative distance of a static route over ad dynamic one. For example, AD of OSPF is 110 and exernal EIGRP has 170. You can "win" both with only 1 to increment. For example you can manage reserve static route for ospf with 111 and 171 with eigrp.
