    我们把实验的命令写到文本:
    基本配置:
    r1:
    en
    conf t
    host r1
    enable pass cisco
    line vty 0 4
    pass cisco
    login
    exit
    int s0/0
    ip addr 192.168.1.1 255.255.255.0
    no shut
    clock rate 64000
    exit
    router rip
    ver 2
    no auto-summary
    network 192.168.1.0
    exit
    r2:
    en
    conf t
    host r2
    enable pass cisco
    line vty 0 4
    pass cisco
    login
    exit
    int s0/0
    ip addr 192.168.1.2 255.255.255.0
    no shut
    int s0/1
    ip addr 192.168.2.1 255.255.255.0
    no shut
    clock rate 64000
    exit
    router rip
    ver 2
    no auto-summary
    network 192.168.1.0
    network 192.168.2.0
    exit
    r3:
    en
    conf t
    host r3
    enable pass cisco
    line vty 0 4
    pass cisco
    login
    exit
    int s0/1
    ip addr 192.168.2.2 255.255.255.0
    no shut
    exit
    router rip
    ver 2
    no auto-summary
    network 192.168.2.0
    exit
    在r2上配置拒绝telnet:
    conf t
    access-list 101 deny tcp 192.168.1.1 0.0.0.0 192.168.2.0 0.0.0.255 eq telnet
    access-list 101 permit ip any any
    int s0/1
    ip access-group 100 out
    exit
    access-list 102 deny tcp 192.168.1.1 0.0.0.0 192.168.2.0 0.0.0.255 eq ftp
    access-list 102 permit ip any any
    int s0/1
    ip access-group 100 out
    exit
    access-list 103 deny icmp 192.168.4.2 0.0.0.0 192.168.1.0 0.0.0.255 echo
    access-list 103 deny icmp 192.168.4.2 0.0.0.0 192.168.1.0 0.0.0.255 echo-reply
    access-list 103 permit ip any any
    int s0/0
    ip access-group 101 out
    写完了以后我们开始粘贴。

控制访问列表(ACCESS LIST) 
    粘贴完并没有错误,我们先不添加访问控制列表看能否telnet
    没有问题可以telnet并打开了

控制访问列表(ACCESS LIST) 
    我们来添加访问列表

控制访问列表(ACCESS LIST) 
    在来telnet 如果失败了,我们就成功了。

控制访问列表(ACCESS LIST) 
    telnet不上了,成功!!!!!!
    凌晨了睡觉喽!!!!!!呵呵 !!!!!!
