Local Link Address
https://www.itdojo.com/ssh-using-link-local-ipv6-addresses/
Because every interface on your system, physical or virtual, has a link local IPv6 address your system needs a little guidance as to which one to use when sending packets to link-local IPv6 addresses.
When using link-local prefixes in each of the OS you need to use this simple syntax:
ipv6-address + percent sign (%) + interface-id.
Linux:
ssh colin@fe80::216:eaff:fe5f:4cad%eth1
Windows:
netsh interface ipv6 show address ssh colin@fe80::216:eaff:fe5f:4cad%10
