IMHO the simplest is to write a little hook which resets the giaddr,

Client is a mikrotik router with some specific setup: lan segment which
it runs relay for is in VRF instance, but there is a limitation in
RouterOS that dhcp-relay destination will be contacted using main
routing table.
Because of that, relay messages are sent out-of-band, using different
interface.
Right now i'm working on supplying additional option 82 information to
kea, by wich it should select appropriate subnet.

Can someone tell me how to make kea select subnet 100.101.101.0/24 by
Remote-ID "100.101.101.0" suboption and giaddr?
Should i define some class and apply it to subnet?
