Lab process:
configure Router 1.
Router>enable
Router#configure terminal
Router(config)#hostname CCNA1
CCNA1(config)#enable password cisco
CCNA1(config)#enable secret cisco1
CCNA1(config)#line vty 0 4
CCNA1(config-line)#login

CCNA1(config-if)#clock rate 64000
CCNA1(config-if)#no shutdown
Configure Router 2 and Router 3 the similar way that Router 1 is configured. The IP addresses of these
interfaces are different. Set the clock rate of the DCE end on every MAN link.
After all these routers are configured, you can view information by using the following commands on
Router 2.
CCNA2#show cdp
(display CDP information)
CCNA2#show cdp neighbors
(display summary information of CDP neighbors)
CCNA2#show cdp neighbors detail
(display detailed information about CDP neighbors)
CCNA2#show cdp traffic
(display information about CDP data packets)
CCNA2#show cdp entry (display all information about adjacent routers)
CCNA2#show cdp entry CCNA1 (display detailed information about adjacent routers)
configure Telnet Remote Access
Lab requirements:
1. The router names are p4s1 and p4s2.
2. Set the privilege password and the vty line password on p4s2.
3. Telnet from p4s1 to p4s2.
4. View other users that telneted to p4s2.
Lab process:
The configuration of p4s2 as follows:
p4s2(config)#enable secret cisco
p4s2(config)#line vty 0 4
p4s2(config-line)#login
p4s2(config-line)#password cisco
p4s2(config-line)#exit
p4s2(config)#int s1/1
p4s2(config-if)#ip add 192.168.12.2 255.255.255.0
p4s2(config)#clock rate 64000
p4s2(config-if)#no shutdown
The configuration of p4s1 are as follows:
p4s1(config)#int s1/1
p4s1(config-if)#ip add 192.168.12.1 255.255.255.0
p4s1(config)#no shutdown
Commands for telneting from p4s1 to p4s2:
p4s1#telnet 192.168.12.2
trying 192.168.12.2 … Open
User Access Verification
Password:
p4s2>enable
Password:
p4s2#
Create and use loopback interface
Lab requirements:
1. The router names are p4s1 and p4s2
2. Create a loopback interface on either of the routers and specify an IP address to every loopback
interface.
3. Delete the loopback interface.
Lab process:
1. The loopback interface is a logical virtual interface on the router. A router has no loopback interfaces
by default, but they can be created on it. In normal cases, a router has fewer interfaces than a switch;
therefore, you need to create loopback interfaces when doing lab. A loopback interface is treated on the
router like a physical interface. It can be assigned an IP address. Loopback interfaces are widely used.
They are enabled by default. To disable a loopback interface, run the shutdown command.
2. create a loopback interface.
P4s1(config)#interface loopback 0
p4s1(config-if)#ip add 192.168.1.1 255.255.255.0
P4s1(config-if)#end
