# This is an example configuration file for the DHCPv4 server in Kea.
# It is a basic scenario with one IPv4 subnet configured. It demnstrates
# how to configure Kea to use various backends to store leases:
# - memfile
# - MySQL
# - PostgreSQL
# - CQL (Cassandra) backend

{ "Dhcp4":

{
# Kea is told to listen on ethX interface only.
  "interfaces-config": {
    "interfaces": [ "ethX" ]
  },

# We need to specify lease type. Exactly one lease-database section
# should be present. Make sure you uncomment only one.

# 1. memfile backend. Leases information will be stored in flat CSV file.
# This is the easiest backend to use as it does not require any extra
# dependencies or services running.
#  "lease-database": {
#      "type": "memfile",
#      "lfc-interval": 3600
#  },

# 2. MySQL backend. Leases will be stored in MySQL database. Make sure it
# is up, running and properly initialized. See kea-admin documentation
# for details on how to intialize the database. The only strictly required
# parameters are type and name. If other parameters are not specified,
# Kea will assume the database is avaiable on localhost, that user and
# password is not necessary to connect and that timeout is 5 seconds.
# Kea must be compiled with --with-dhcp-mysql option to use this backend.

# 3. PostgreSQL backend. Leases will be stored in PostgreSQL database. Make
# sure it is up, running and properly initialized. See kea-admin documentation
# for details on how to intialize the database. The only strictly required
# parameters are type and name. If other parameters are not specified,
# Kea will assume the database is avaiable on localhost, that user and
# password is not necessary to connect and that timeout is 5 seconds.
# Kea must be compiled with --with-dhcp-pgsql option to use this backend.

#      "password": "secret1"
#  },

# 4. CQL (Cassandra) backend. Leases will be stored in Cassandra database. Make
# sure it is up, running and properly initialized. See kea-admin documentation
# for details on how to intialize the database. The only strictly required
# parameters are type, keyspace and contact_points. At least one contact point
# must be specified, but more than one is required for redundancy. Make sure
# you specify the contact points without spaces. Kea must be compiled with
# --with-cql option to use this backend.

#      "type": "cql",
#      "keyspace": "keatest",

# Renew and rebind timers are commented out. This implies that options
# 58 and 59 will not be sent to the client. In this case it is up to
