/// - Configuration 0:
-/// - Used for testing direct traffic
-/// - 1 subnet: 10.0.0.0/24
-/// - 1 pool: 10.0.0.10-10.0.0.100
-/// - Router option present: 10.0.0.200 and 10.0.0.201
-/// - Domain Name Server option present: 10.0.0.202, 10.0.0.203.
-/// - Log Servers option present: 192.0.2.200 and 192.0.2.201
-/// - Quotes Servers option present: 192.0.2.202, 192.0.2.203.
+/// - Used to test that host specific options override subnet specific
+/// options when these options are requested with PRL option.
+/// - Single subnet 10.0.0.0/24 with a pool of 10.0.0.10-10.0.0.100
+/// - 4 options configured within subnet scope
+/// - routers: 10.0.0.200,10.0.0.201,
+/// - domain-name-servers: 10.0.0.202,10.0.0.203,
+/// - log-servers: 10.0.0.200,10.0.0.201,
+/// - cookie-servers: 10.0.0.202,10.0.0.203
+/// - Single reservation within the subnet:
+/// - HW address: aa:bb:cc:dd:ee:ff
+/// - ip-address: 10.0.0.7
+/// - Two options overriding subnet specific options:
+/// - cookie-servers: 10.1.1.202, 10.1.1.203
+/// - log-servers: 10.1.1.200, 10.1.1.201
+///
+/// - Configuration 1:
+/// - Used to test that host specific options override subnet specific
+/// default options. Default options are those that are sent even when
+/// not requested by a client.
+/// - Single subnet 10.0.0.0/24 with a pool of 10.0.0.10-10.0.0.100
+/// - 4 options configured within subnet scope
+/// - routers: 10.0.0.200,10.0.0.201,
+/// - domain-name-servers: 10.0.0.202,10.0.0.203,
+/// - log-servers: 10.0.0.200,10.0.0.201,

+/// - Single reservation within the subnet:
+/// - HW address: aa:bb:cc:dd:ee:ff
+/// - ip-address: 10.0.0.7
+/// - Two options overriding subnet specific default options:
+/// - routers: 10.1.1.200, 10.1.1.201
+/// - domain-name-servers: 10.1.1.202, 10.1.1.203
+///
+/// - Configuration 2:
+/// - Used to test that host specific vendor options override globally
+/// specified vendor options.
+/// - Globally specified option 125 with Cable Labs vendor id.
+/// - TFTP servers sub option: 10.0.0.202,10.0.0.203
+/// - Single subnet 10.0.0.0/24 with a pool of 10.0.0.10-10.0.0.100
+/// - Single reservation within the subnet:
+/// - HW address: aa:bb:cc:dd:ee:ff
+/// - ip-adress 10.0.0.7
+/// - Vendor option for Cable Labs vendor id specified for the reservation:
+/// - TFTP servers suboption overriding globally spececified suboption:
+/// 10.1.1.202,10.1.1.203
