Cisco IPV6 DHCP Server Configuration

IPV6 DHCP Server configuration on a Cisco device is very similar to a normal, IPV4 configuration, but there is a big difference that you will want to make sure to not miss. Everything can be broken down into the following three steps:

Create the IPV6 DHCP Pool

Configure \ Apply the pool to an interface

Configure the clients for DHCP.

I do want to call out that this is a basic server configuration and that the understanding of stateful and stateless IPV6 DHCP configuration is the next level of this. This configuration is meant to be able to get a basic working lab established for instance.

Create the IPV6 DHCP Pool

Creating the pool is very similar to an IPV4 DHCP pool. This is straight forward and pretty simple once you select a subnet to use.

Configure \ Apply the pool to an interface

We created the pool, next we need to enable this for use. We will want to use it on interface e0/0 of the Server in our lab, as seen above. There are two ways to do this. First you select the interface for configuration and then use the following command:

Everything is pretty straight forward and it’s one of those topics to be aware of for sure and make some notes on if that helps you remember it. Not a difficult topic to cover though. If your personal lab testing IPV6 DHCP server configuration has any issues, comment below!

This way all your clients won’t do SLAAC, EUI-64 and a local mulitcast address as well. Clients now get a nice single IP address. And don’t forget to enable RA-Guard on all your access switches to block RA’s from malicious endpoints that try to steal the router’s role.
