CCNA ICND2 Lab 3 - CDP Command Operations

Lab Topology:

Lab Requirements:

1. Router name: P4S1, P4S2, P4S3

2. Set password to cisco, secret to cisco1, and vty to cisco. All the passwords are required to be encrypted.

3. Configure all these routers.

Lab Process:

Configure Router 1.

Router>enable

Router#configure terminal

Router(config)#hostname P4S1        / set router name

P4S1(config)#enable password cisco             / set enable password

P4S1(config)#enable secret cisco1                 / set encryption password

P4S1(config)#line vty 0 4                         / set VTY line mode

P4S1(config-line)#login                    / set password authentication

P4S1(config-line)#password cisco            / set line password

P4S1(config-line)#exit

P4S1(config)#service password-encryption            / encrypt all the passwords globally

P4S1(config)#interface serial 1/1                 / enter the interface you want to configure

P4S1(config-if)#ip add 202.119.249.1 255.255.255.0       / set the IP address of the interface

P4S1(config-if)#clock rate 64000              / set the clock rate for the interface

P4S1(config-if)#no shutdown          / activate the password

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.

P4S2#show cdp          / display CDP information

P4S2#show cdp neighbors              / display summary information about CDP neighbors

P4S2#show cdp neighbors detail          / display detailed information about CDP neighbors

P4S2#show cdp traffic               / display information about CDP data packets

P4S2#show cdp entry *            / display all the information about adjacent routers

P4S2#show cdp entry P4S1         / display detailed information about adjacent routers
