Creating an IPv6 Network Interface
When configuring an IPv6 interface, a link-local address (FE80::x:x:x:x:x:x:x/64) is
automatically generated after the CLI command ipv6 is given. If the port is already assigned
to the interface when IPv6 is enabled, the link-local address is derived from the port MAC
address. Otherwise, the link-local address is derived from the system MAC address.
In either case, if the configuration file is saved and the node is rebooted, the port will be
assigned to the interface before IPv6 is enabled and the link-local address will be derived
from the port MAC address. This means that the link-local address will change after the node
is rebooted if it was derived from the system MAC address before the reboot.
To avoid having the link-local address change after a reboot, IPv6 on the interface should be
configured in the following order. This will ensure that the link-local address is derived from
the port MAC address and will therefore not change after a reboot.
