Perform Basic Router Configuration.
Step 1: Use global configuration commands.
On the routers, enter global configuration mode and configure the basic global configuration commands including:
? hostname
? no ip domain-lookup
? enable secret
Step 2: Configure the console and virtual terminal line passwords on each of the routers. ? password
? login
Step 3: Add the logging synchronous command to the console and virtual terminal lines. This command is very helpful in both lab and production environments and uses the following syntax: Router(config-line)#logging synchronous

To synchronize unsolicited messages and debug output with solicited Cisco IOS software output and prompts for a specific console port line, auxiliary port line, or virtual terminal line, we can use the logging synchronous line configuration command. In other words, the logging synchronous command prevents IOS messages delivered to the console or Telnet lines from interrupting your keyboard input.

For example, you may have already experienced something similar to the following example: Note: Do not configure R1 interfaces yet.
R1(config)#interface fastethernet 0/0
R1(config-if)#ip address 172.16.3.1 255.255.255.0
R1(config-if)#no shutdown
R1(config-if)#descri
R1(config-if)#
The IOS sends unsolicited messages to the console when you activate an interface with the no shutdown command. However, the next command you enter (in this case, description) is interrupted by these messages. The logging synchronous command solves this problem by copying the command entered up to that point down to the next router prompt. R1(config)#interface fastethernet 0/0

R1(config-if)#ip address 172.16.3.1 255.255.255.0
R1(config-if)#no shutdown
R1(config-if)#description
R1(config-if)#description
