===================
LAB 10 – IP 访问列表
实验一:将naxxr2, naxxr3 认为是一台计算机,R1 是路由器,配置标准访问列表,
不允许naxxr2 访问naxxr3.
1. 做好基本配置,并测试连通性
Naxxr1:
naxxr1#conf t
naxxr1(config)#int s0
naxxr1(config-if)#ip add 12.1.1.1 255.255.255.0
naxxr1(config-if)#clock rate 64000

naxxr2(config-if)#exit
naxxr2(config)#ip route 0.0.0.0 0.0.0.0 12.1.1.1
naxxr2(config)#end
naxxr2#ping 13.1.1.3
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 13.1.1.3, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 4/7/8 ms
NAXXR3:
Router>en
Router#conf t
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#hostname naxxr3
naxxr3(config)#interface serial 0
naxxr3(config-if)#ip add 13.1.1.3 255.255.255.0
naxxr3(config-if)#no shutdown
naxxr3(config-if)#exit
naxxr3(config)#ip route 0.0.0.0 0.0.0.0 13.1.1.1
naxxr3(config)#end
naxxr3#ping 12.1.1.2
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 12.1.1.2, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 4/6/8 ms
naxxr3#
2.naxxr1(config)#access-list 1 deny 12.1.1.2 0.0.0.0
naxxr1(config)#access-list 1 permit any
naxxr1(config)#interface s1
naxxr1(config-if)#ip access-group 1 out !如将列表应用在S0 口,怎么配置呢?
naxxr1#show access-list !或者使用show ip access-list
naxxr1#show ip interface
在naxxr2# 上测试Ping naxxr3
naxxr2#ping 13.1.1.3 !是否能Ping 通?
naxxr2#telnet 13.1.1.3 !能Telnet 到成功吗？
naxxr1#conf t
naxxr1(conft)#no access-list 1 !删除列表1
naxxr1#show run !检查列表1,还有列表吗?

对好多初学者有帮助，顶！
