In this video, Keith Barker covers why you need IPv6 DHCP relays when clients aren’t on the same Layer 2 domains as a DHCP server. This comprehensive overview will explain what this function does, how it works, how to configure it, and wraps up with an overview of verification steps.
Keith begins by using the scenario of having a hundred subnets, all of which need DHCP functionality.
You could make every router supporting those subnets a DHCP server, but configuring twenty to thirty servers isn’t very manageable, doesn’t scale well, and it’s far from a pleasant experience.
The alternative is to use a centralized DHCP server (in a production environment, you’ll likely have a couple for fault tolerance purposes).
You’ll instruct the DHCP server to listen for any clients making a DHCP request, and when that happens, the server will wrap it up and send it over to the DHCP server via Unicast.
This is the underlying process for a DHCP relay, and Keith will walk you through how to configure this setup and then verify it’s working.
