Hi Rene
Just a question, more of a general IPV6 question, why does a loopback interface generate the same link-local address as the physical interface. Yes I understand that the loopback don’t have it’s own mac address and will use the physical interface, but why doesn’t it cause a conflict on the local device, I was under the impression the link-local address must be unique on the llocal device:
