I just started this lab and while I feel I have a ways to go to understand IPV6 better I have some questions hopefully someone can help shed some light on.
The lab states: Devices using a Unique Local Address should use an address where the subnet ID is based on the last two octets of the IPv4 address for the same vlan. You have assigned yourself AB:CDEF:1234 for the global ID. Only interfaces which will have clients requiring this support should be configured. We go on to add the following to the vlans that will serve clients. int vlan 12 ip address 10.10.12.3 255.255.255.0 ipv6 address FE80::2 link-local ipv6 address FDAB:CDEF:1234:0C03::/64 eui-64 So I understand the AB:CDEF:1234:0C03 where 0C is equal to 12 (VLAN number) and 03 the last octet of the ipv4 address. So 2 questions: 1. What is the FD in front for? In Dec its 253? Not following where/why this came from. 2. The requirement was to apply it to interfaces that will have clients requiring this support. In our main site this is equal to our "HQData" vlans. However, we don't assign this to our remote sites "MOData vlan". How was I suppsoed to identify which interfaces "have clients requiring this support"? Is there a line I'm not reading between or other information I've not read?
