You use it to specify a link local address of your choice, or else it would
use the EUI64 for the last 64 bits. Makes things easier in my opinion for
management :P
I tried on my router and it only accepts link local address beginning with
FE80::/10. If you specify a unicast address, it will automatically use the
EUI64 for the link local.

Subject: IPv6 link local address
Hi guys,
Since ipv6 automatically creates a link local address for every interface
configured with a unicast ipv6 address, why would anyone want to use the
link-local option on the following command?
int e0/0
ipv6 address <ipv6-addr> </length | link-local>
Also, what ipv6 addresses are allowed when the link-local option is used?
In other words, does the ip v6 address have to start with FE80::/10 or can
any allowed ipv6 unicast address be used and then ipv6 will automatically
construct a legal link-local address from the unicast address?
Thanks, Tim
