48 Chapter 3: Starting and Configuring the Router 5000

In general, the configuration steps are as follows:

1 Before configuring the router, the networking requirements should be 

made specific, which include networking purpose, the role of the router 
in the network, the division of subnets, WAN type and transmission 
medium, the network security policy and reliability.

2 Based on the above requirements, draw a clear and integrated 

networking diagram.

3 Configure the WAN interface of the router. First, configure the physical 

operating parameters (e.g., the operating mode of the serial interface, 
baud rate and synchronous clock) of the interface according to the 
transmission medium of the WAN. For the dial-up interface, the user also 
needs to configure DCC parameters. Then, configure the link layer 
protocol encapsulated on the interface and the related operating 
parameters according to the WAN type.

4 Configure the IP addresses or IPX network numbers of all the interfaces 

on the router according to the division of the subnets.

5 Configure the routes. If it is necessary to enable a dynamic routing 

protocol, the user should configure the related operating parameters of 
the protocol.

6 If special security is required, perform the security configuration for the 

router.

7 If special reliability is required, perform the reliability configuration for the 

router.

The command line interface of the Router 5000 provides a number of 
configuration commands, which can be used to configure and manage 
the router. The command line interface has the following characteristics:

■

Performs the local configuration through CON port.

■

Performs the local or remote configuration through telnet command, 
which can be used to directly log on and manage other routers.
