  • Options Configuration Host Reservations Kea 1.0 Quick Start
    Interfaces Options configuration You can specify an interface (all traffic including Options can be configured either at the global broadcast), a specific address (unicast traffic) or level (will apply to clients in all subnets) or on use “*” to denote all traffic on all interfaces. subnet-level (will be sent only to clients in that subnet). Kea supports standard, custom, vendor specific and nested options. Subnets Change the subnet definition to match your network by adding and removing subnets. Host Reservations Directly connected subnets require the "interface" Kea 1.0 supports host reservations based on object, as shown in the example. MAC address (v4) or DUID (v6), with IPv4 address and hostname reservations. Kea 1.1 will also support reservations for IPv6 addresses, IPv6 Lease Database prefixes and host specific options. If you are using Kea can store leases in memfile (a flat CSV file) or Host Reservation, you may want to download the SQL databases (MySQL or PostgreSQL). The latest source. example configuration uses flat file lease storage If you have few reservations, defining them in the (memfile), which is the highest performance configuration file is convenient. Kea can also option. store host reservations in MySQL, with Postgres Kea 1.0 support coming soon. Quick Start Guide In order to configure MySql or PosgreSQL use "hosts-database": { Kea is a modern open-source DHCP server for the following guide: "type": "mysql", Linux and Unix variants. This guide will help “host”: “mysql- you get a server up and running quickly. To configure MySQL: server.example.com”, "name": "keadatabase", "lease-database": { "user": “kea”, Kea is licensed under the Mozilla Public License "type": "mysql", “password”: “secret1” version 2 (MPL 2.0).
