# Definition: dhcp::subnet
#
# Creates a subnet
#
# Parameters:
# ['broadcast'] : subnet broadcast (mandatory)
# ['netmask'] : subnet netmask
# (default: $::netmask_eth0)
# ['routers'] : An array of subnet routers
# (default: $::netmask)
# ['subnet_mask'] : netmask sent to dhcp guests
# (default: the value of $netmask)
# ['domain_name'] : subnet domain name
# (default: $::domain)
# ['other_opts'] : An array of additional DHCPD options
# ['is_shared'] : whether it's part of a shared network or not
# (default: false)
#
# Sample usage:
# dhcp::subnet {"10.27.20.0":
# ensure => present,
# broadcast => "10.27.20.255",
# other_opts => ['filename "pxelinux.0";', 'next-server 10.27.10.1;'],
# }
