[Kea-users] Overlapping Subnets

[Martijn Remmen]

Hi Matt,

We have the same use case (running dhcp services for multiple VRFs). We run a kea instance for each vrf. Back when we researched this, it was not possible with a single kea instance.

We have a systemd template for the kea service, and can manage the service with ‘systemctl start kea-dhcp4 at vrf111’.

It has its pros and cons. I guess you could also look at containers.

We previously used LXC, but had issues with maintaining all the containers. I feel like our current solution is a lot easier to maintain.

Let me know if you have any questions.

Regards,

Martijn
