[3874] Added example configuration for setting up DUID.

parent 9fac2d53
# This is an example configuration file for DHCPv6 server in Kea.
# It demonstrates how to configure Kea to use DUID-LLT with some
# values specified explicitly.
{ "Dhcp6":
# Configure server identifier (DUID-LLT). The hexadecimal value of the
# identifier will be used as link layer address component of the DUID.
# The link layer type will be ethernet. The value of time is set to 0
# which indicates that the server must generate this value, i.e. use
# current time. Note that it is easy to move from this configuration
# to DUID-EN or DUID-LL. It would require changing the "type" value
# to "EN" or "LL" respectively. The "identifier" would hold a
# DUID-EN variable length identifier or DUID-LL link layer address.
# The values of "time" and "htype" would be ignored for DUID-EN.
# If one wanted to use a non-default enterprise-id for DUID-EN, the
# "enterprise-id" parameter would need to be added. Note that only
# a "type" parameter is mandatory while specifying "server-id" map.
