> A, B, C , D can ping each others using the local link IP `fe080::....`
Why I got confused is that the attachment shows that ping from node2 to node1
with link-local address fails .

> A, B, C can ping D on <PREFIX>::10, and D can ping A, B, C on their <PREFIX> .
This looks like port isolation is tuned on, and A, B, C are in private VLAN.

Do you have physical access to the environment? Can you please exchange the
switch port of A with that of D ? Then the setup looks like this:

         |- ::10 machine D
         |- ::12 machine B
SWITCH --|- ::13 machine C
         |
         |- ::11 machine A

Then ping global IPv6 address from B to D, and B to A .


> Using Linux this is working perfectly and th eissue is not reproduced.
Do you mean that with same switch and machines, but A, B and C boot into Linux
?
