The first entry in Figure 3-42 indicates: If there are packets being sent to a device with IP address of
172.31.70.28 and subnet mask of 255.255.255.0, the Router will forward the packets from WAN1 port
to the next hop of 116.10.1.254.
Application Example
There is a network topology as the following figure shown:
If the LAN port of TL-ER5120（with Non-NAT or Classic system mode）is connected to LAN1 with
subnet of 192.168.0.0/24, while the LAN port of another Router R1 is connected to LAN2 with network
of 192.168.2.0/24. Meanwhile, the WAN ports of the two routers are interconnected and within the
same network. Now a host under TL-ER5120 and within network of LAN1 desires to communicate with
the host within network of LAN2.
You can set a Static Route entry: Enter the WAN IP address of R1 (116.31.88.16) in the Next Hop field
on the Static Route page of TL-ER5120 as the following figure shown, then click the <Add> button to
save the entry.
RIP (Routing Information Protocol) is a dynamic route protocol using distance vector algorithm to select
the optimal path. With features of easy configuration, management and implementation, it is widely used
in small and medium-sized networks such as the campus network.
