Hi,

I am trying to troubleshoot an issue, and I do not know where to start.

I am running a CRS328 in my home/lab environment. the setup seems to be working fine, as long as i stick to RouterOS 6.47.10 or below.
When I upgrade to a newer Version (most recent test was done with RouterOS 7.13) i loose IPV6 ND (Neighbor Discovery - counterpart of ARP in IPv4).

how do i troubleshoot this further?
what sort of additional information should i provide?
