[Kea-users] Multiple HA Configurations for one server

[Darren Ankney]

Hi Kraishak,

Currently there is no such possibility in Kea HA hook.  Only the
servers themselves are able to be in a primary and secondary
relationship and there can be only two.  What you can do is use a
database  server (mysql or postgres) storage for leases and point all
servers with the same subnets configured at the same database (be sure
and give the subnets matching ids on all servers or that could be
interesting).  This is more feasible after the random lease allocator
was introduced in version 2.3.4 as multiple Kea servers are less
likely to offer the same address to multiple clients.

Thank you,

Darren Ankney
