1.11.2 Example for Configuring Routed Proxy ARP
Routed proxy ARP implements communication between the two branches on the same network
segment but on different physical networks.
Networking Requirements
As shown in Figure 1-2, branch A and branch B of a company are located in different cities;
multiple routing devices are deployed between branches and routes are reachable; IP addresses
of the routing devices are on the same network segment 172.16.0.0/16. Branch A and branch B
belong to different broadcast domains; therefore, they cannot communicate on a LAN. Hosts of
branches are not configured with default gateway addresses; therefore, they cannot communicate
across network segments. The company requires that branch A and branch B communicate
without changing the host configurations.
NOTE
AR150/200 is RouterA or RouterB.
