Description

Currently, the ISC DHCPv6 daemon doesn't support failover, instead they recommend that unique pools be run independently on different servers.

We have a couple options that we can use to make this somewhat easier, such as adding a checkbox option to activate a CARP check, similar to OpenVPN clients, that only runs the DHCPv6 server if the CARP interface is in a MASTER state and kills it if it is in a BACKUP state. Using that method the same pool could run on both nodes, however it would not support a mix of CARP and non-CARP subnets on the two nodes, and it would not share leases.
