48Chapter 3: Starting and Configuring the Router 5000

Configuration	In general, the configuration steps are as follows:
Fundamentals of
the Router

1Before 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.

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

3Configure 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.

4Configure the IP addresses or IPX network numbers of all the interfaces on the router according to the division of the subnets.

5Configure the routes. If it is necessary to enable a dynamic routing protocol, the user should configure the related operating parameters of the protocol.

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

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

Command Line	Characteristics of the command line interface
Interface	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.
	■ Users can enter ? anytime to get online help.
