Spectrum IPv6 - unreachable?

RouterOS Beginner Basics
1

Hey guys, I’ve been trying to get IPv6 working now that Spectrum finally supports it natively. I’ve given you as much debug output as I can think of below, let me know if you need anything else. Right now I can ping IPv6 addresses from the router WAN, but the routes say “unreachable” and if I ping from the router bridge (or a LAN client) I get nada.

Current Configuration:

# sep/30/2017 03:55:49 by RouterOS 6.40.3
# software id = VHAA-IM7V
#
# model = RouterBOARD 3011UiAS
/ipv6 dhcp-server
add interface=bridge name=default
/ipv6 address
add from-pool=charter-ipv6 interface=bridge
/ipv6 dhcp-client
add add-default-route=yes interface=ether1 pool-name=charter-ipv6 prefix-hint=::/64 request=prefix
/ipv6 nd
set [ find default=yes ] advertise-dns=yes other-configuration=yes
/ipv6 settings
set accept-router-advertisements=yes forward=no

Your router only has one IP address and no link-local addresses. I am not 100% sure but I think you’re not going be doing much routing if you only have one IP.
Does anything show up in the neighbour table? [/ipv6 neighbor print]

Flags: R - router 
 0   address=ff02::1 interface=ether1 mac-address=33:33:00:00:00:01 status="noarp" 

 1   address=ff02::c interface=bridge mac-address=33:33:00:00:00:0C status="noarp" 

 2 R address=fe80::201:5cff:fe69:9846 interface=ether1 mac-address=00:01:5C:69:98:46 status="stale" 

 3   address=fe80::2dfb:8c1f:b621:a1f4 interface=bridge mac-address=F4:F2:6D:96:77:ED status="stale"

Also, considering 100% of the tutorials for configuring a 6to4 tunnel on the MikroTik don’t mention link-local, I think it is definitely irrelevant. According to this link local IPs are used for router to router communication, and the MikroTik handles setting up the link-local IP to the ISP router.

Also I do get a link-local IP on my LAN clients.

Not sure what exactly I did, but it all started working. I re-enabled “IPv6 Forward” and set “Accept Router Advertisements” to “yes” instead of “yes if forwarding disabled”. Seems to have done the trick, but I had to give it 5 minutes or so to kick in.
