    一、项目案例要求

      1.企业内网运行OSPF路由协议,区域规划如图所示;
      2.财务和研发所在的区域不受其他区域链路不稳定性影响;
      3.R1、R2、R3只允许被IT登录管理;
      4.YF和CW之间不能互通,但都可以与IT互通;
      5.IT和YF可以访问Client1,但CW不能访问Client1;
      6.YF和CW只能访问Server1的WWW服务;

    二、项目规划

      CW

    三、项目实施

      1.配置基本网络 

      R1

      [R1]int g0/0/0

      [R1-GigabitEthernet0/0/0]ip address 1.1.1.254 24

      [R1-GigabitEthernet0/0/0]int g0/0/1

      [R1-GigabitEthernet0/0/1]ip address 192.168.12.1 24

      [R1-GigabitEthernet0/0/1]int g0/0/2

      [R1-GigabitEthernet0/0/2]ip address 192.168.13.1 24

      [R1-GigabitEthernet0/0/2]q

     

      R2

      [R2]int g0/0/0

      [R2-GigabitEthernet0/0/0]ip address 192.168.12.2 24

      [R2-GigabitEthernet0/0/0]int g0/0/1

      [R2-GigabitEthernet0/0/1]ip address 192.168.10.254 24

      [R2-GigabitEthernet0/0/2]q

      R3

      [R3]int g0/0/0

      [R3-GigabitEthernet0/0/0]ip address 192.168.13.2 24

      [R3-GigabitEthernet0/0/0]int g0/0/1

      [R3-GigabitEthernet0/0/1]ip address 192.168.30.254 24

      [R3-GigabitEthernet0/0/1]int g0/0/2

      [R3-GigabitEthernet0/0/2]ip address 192.168.40.254 24

      [R3-GigabitEthernet0/0/2]q

      IT

      [IT]int g0/0/0

      [IT-GigabitEthernet0/0/0]ip address 192.168.10.1 24

      [IT-GigabitEthernet0/0/0]q

     

      2.配置OSPF

     

      R1

      [R1]ospf 1

      [R1-ospf-1]area 0

      [R1-ospf-1-area-0.0.0.0]network 192.168.12.0 0.0.0.255

      [V200R003C00]

      #

       area 0.0.0.0

        network 192.168.13.0 0.0.0.255

      #

      return

      [R3-ospf-1-area-0.0.0.0]q

      [R3-ospf-1]area 3

      [R3-ospf-1-area-0.0.0.3]network 192.168.30.0 0.0.0.255

      [R3-ospf-1-area-0.0.0.3]network 192.168.40.0 0.0.0.255

      #

      return

      [R3-ospf-1-area-0.0.0.3]q

      IT

      [IT]ospf 1

      [IT-ospf-1]area 2

      [IT-ospf-1-area-0.0.0.2]network 192.168.10.0 0.0.0.255

      #

      return

      [IT-ospf-1-area-0.0.0.2]q

      此时检查网络中都可以互相连通:

      

       

       3.配置ACL

      CW:

      [R3]acl 3000

      [R3-acl-adv-3000]rule 5 deny ip source 192.168.30.0 0.0.0.255 destination 1.1.1.

      [R3-acl-adv-3000]rule 20 deny ip source 192.168.30.0 0.0.0.255 destination 192.1

      68.40.1 0

      [R3-acl-adv-3000]q

      [R3]int g0/0/1

      [R3-GigabitEthernet0/0/1]traffic-filter inbound acl 3000

      [R3-GigabitEthernet0/0/1]q
