  1. Quick question Rene, if you were to omit the IPv6 global unicast address on the tunnel interface, would you need to use “ipv6 enable” instead so OSPFv3 could use a link local address? Or does enabling OSPFv3 on the interface automatically generate a link local address?

  2. Hi Chris,

    You’ll need to configure an IPv6 address or use “ipv6 enable”. Without an address, you get an error:

    R1(config)#interface GigabitEthernet 0/1
    R1(config-if)#ipv6 ospf 1 area 0
    % OSPFv3: IPV6 is not enabled on this interface
