Ok, but it is related to www interface only - in cli and Winbox there is no limit (like on www before 7.23)
Thanks. That seems to have worked. I got rid of "all" and added my bridges and "break glass" interface and IPv6 is working with 7.23.3. I don't see anything about a paused automatic RA in the logs.
/ipv6 nd
set [ find default=yes ] advertise-dns=yes interface=bridge
add interface=bridge101
add interface=ether8
/ipv6 nd settings
set router-advertisement-ignored-options=mtu
That ignore MTU option is there because I get log spam from Comcast on the WAN interface about an invalid MTU of 9192. I figure if it's logging that it's invalid every couple of seconds I might as well ignore it. It's not going to use it anyway and it makes my logs hard to read.
There is a red warning over the items already there from before the upgrade, if they have the options like DNS / MTU etc... enabled. You can see the screenshots in this post:
After the upgrade, once you make an edit to those items and save, the warning is removed, and the spamming of RA is no longer paused.
