1.1 DHCPの基本設定
以下ではCisco WLCのIPをオプション43にて通知している。

# If this DHCP server is the official DHCP server for the local
# [[network]], the authoritative directive should be uncommented.

# No service will be given on this subnet, but declaring it helps the
# DHCP server to understand the network topology.
