Basic configuration of the router

Preparation of the device configuration

Modify the session timeout, set to never time out.

Router (config) #line console 0Router (config-line) #exec-timeout 0 0

Prevents the console from automatically displaying information that can be enabled for display synchronization.

Router (config) #line console 0Router (config-line) #logging synchronous

disabling DNS queries

Router (config) #no IP domain-lookup

Show all commands that are currently routed

Router#show Running-config

Configuring IP addresses for routing

Router (config) #interface fastethernet 0/0router (config-if) #ip address 192.168.1.1 255.255.255.0Router (config-if) #no Shutdown \ \ Open Routing interface

Configure IP addresses for the switch

Switch (config) #interface vlan 1Switch (config-if) #ip address 192.168.1.1 255.255.255.0Switch (config-if) #no shutdown

Configuration instance

The f0/0 of the router and the F0/1 of the switch are connected to each other through the console port of the PC connection device to configure the device IP address.
