16 *
17 * This example shows how to generate neighbor caches in various scopes.
18 *
19 * This example shows how to generate neighbor caches on the scope of
20 * a channel, a NetDeviceContainer, an InterfaceContainer and globally.
21 * The example also shows a scenario that auto-generated neighbor caches
22 * can avoid dropping packets because of ARP message or Neighbor Discover
23 * message.
24 * If the user runs the example without any command line option, NeighborCacheHelper
25 * will generate neighbor cache for all devices and the output is their
26 * ARP table or NDISC table, the user can also generate neighbor cache on different
27 * scope by adding command line option --useChannel (on specific channel),
28 * --useNetDeviceContainer (on specific netDeviceContainer) and --useInterfaceContainer
29 * (on specific netDeviceContainer), --noGenerate (don't generate neighbor cache).
30 * The user can also enable --sendTraffic flag to send a data stream from n0 to n1,
31 * the output will be the information of received packets, which shows the packets loss
32 * are reduced after pre-generate neighbor caches.
