division of subnets, WAN type and transmission medium, the network security policy
and reliability.
Step 2: Based on the above requirements, draw a clear and integrated networking
diagram.
Step 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.
Step 4: Configure the IP addresses or IPX network numbers of all the interfaces on the
router according to the division of the subnets.
Step 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.
Step 6: If special security is required, perform the security configuration for the router.
Step 7: If special reliability is required, perform the reliability configuration for the router.
