Simple hack to try:<br>
<br>
log to the network node and go to network namespace of dhcp agent
or router. Use ping6 to ff02::1 (with interface, f.e.: ping6 -I
qr-bda2b276-72 ff02::1). If network is fine, you should receive
reply from all nodes on the segment (link local ipv6 works without
dhcp). And you can track down those requests over interfaces with
tcpdump.<br>
