实验环境

实验一

R2无法ping通R3

R3命令行

R3(config)#access-list 10 deny host 2.2.2.2           
R3(config)#access-list 10 permit any
R3(config)#int e 0/0
R3(config-if)#ip access-group 10 in
R3(config-if)#

R2命令行

R2#ping 3.3.3.3 source 2.2.2.2
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 3.3.3.3, timeout is 2 seconds:
