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

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)#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?
