How to configure RIPNG on Cisco IOS Router

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:

R8#sh ipv6 int brief
Em0/0                  [administratively down/down]
    unassigned
GigabitEthernet0/0     [up/up]
    FE80::6273:5CFF:FEF8:D8E0
GigabitEthernet0/1     [up/up]
    unassigned
Serial0/0/0            [down/down]
    unassigned
Loopback0              [up/up]
