DHCPv6 relay agent remote-id option as identifier
DHCPv6 relay agent remote-id option as identifier:
Specific clients may need to be offered a lease on the same IPv6 address.
The UID and the IAID values of a client might not remain unchanged over time.
It may therefore be useful to users that the relay agent “remote-id” option
alone could be used as a lease identifier.
A hook that performed this operation would need to ensure that Kea "remembers"
the original UID and IAID values so they may be returned correctly to the
client in replies
