CCNA实验大全
一、CDP 的配置。
192.168.1.1 192.168.1.2 2 S1/1 1 S1/1 S1/0 172.16.1.1
172.16.1.2
S1/0 3
要求:a、 配置接口的信息。
b 、R1能ping通R2,R2能ping通R3;
c、在R2 S1/0关闭cdp,使R1不能发现R2,但R3可以发现R2;
d、 R2在全局的模式下关闭cdp,让所有的路由器间不能相互发现对方。 注:如果路由器之间连接帧中继,需要封装encapsulation frame-relay 步骤:1、配置基本信息 Router(config)#hostname R1 R1(config)#no ip domain-lookup R1(config)#line con 0
R1(config-line)#logging syn R1(config-line)#exec-timeout 0 R1(config)#interface s1/1 R1(config-if)#no shutdown

R3(config-if)#ip address 172.16.1.2 255.255.0.0 2、R1能ping通R2,R2能ping通R3; r1#ping 192.168.1.2
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 192.168.1.2, timeout is 2 seconds: !!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 48/56/88 ms R2#ping 172.16.1.2

R2 Ser 1/0 132 R 7206VXR Ser 1/1 4、R2在全局的模式下关闭cdp,让所有的路由器间不能相互发现对方。 先在R2的s1/0开启cdp,然后在配置no cdp run (关闭整个路由的CDP)
R2(config)#no cdp run r1#show cdp neighbors
Capability Codes: R - Router, T - Trans Bridge, B - Source Route Bridge
S - Switch, H - Host, I - IGMP, r - Repeater
Device ID Local Intrfce Holdtme Capability Platform Port ID r3#show cdp ne
