I found something weird that might be a bug.
If I do doas ifconfig vport0 inet6 fe80::2/10 Then ping6 fe80:b2b:11fe:161::2%vport0 On the tcpdump output, I see a different address 20:31:15.816576 fe80::fce1:baff:fed1:b34 > ff02::1:ff00:2: icmp6: neighbor sol: who has fe80:0:11fe:161::2 -- Nicolas Goy Engineer & Developer https://www.kuon.ch https://www.goyman.com
