Wah simple configuration of the simulator ospf

Network requirements
(1) run all switches control housing, and dividing the entire autonomous system into three areas.
(2) wherein switchA switchB as ABR and to forward routes between areas.
(3) configuration, all switches can learn routes to all network segments within each AS.

2. Experimental topology is as follows

Configuration steps

3. 配置步骤
   (1) 配置各接口的 IP 地址
   例SwitchB：
   <H3C>sys
   [H3C]hostname SwitchB
   [SwitchB]vlan 100
   [SwitchB-vlan100]port g 1/0/10
   [SwitchB-vlan100]quit
   [SwitchB]vlan 200
   [SwitchB-vlan200]port g 1/0/20
   [SwitchB-vlan200]quit
   [SwitchB]inter vlan 100
   [SwitchB-Vlan-interface100]ip add 10.1.1.2 24
   [SwitchB-Vlan-interface100]quit
   [SwitchB]inter vlan 200
   [SwitchB-Vlan-interface200]ip add 10.3.1.1 24
   [SwitchB-Vlan-interface200]quit
   [SwitchB]

(2) 配置 OSPF 基本配置
配置 Switch A。
<SwitchA> system-view
[SwitchA] router id 10.2.1.1
[SwitchA] ospf
[SwitchA-ospf-1] area 0
[SwitchA-ospf-1-area-0.0.0.0] network 10.1.1.0 0.0.0.255
[SwitchA-ospf-1-area-0.0.0.0] quit
[SwitchA-ospf-1] area 1
[SwitchA-ospf-1-area-0.0.0.1] network 10.2.1.0 0.0.0.255
[SwitchA-ospf-1-area-0.0.0.1] quit
[SwitchA-ospf-1] quit

配置 Switch B。
<SwitchB> system-view
[SwitchB] router id 10.3.1.1
[SwitchB] ospf
[SwitchB-ospf-1] area 0
[SwitchB-ospf-1-area-0.0.0.0] network 10.1.1.0 0.0.0.255
[SwitchB-ospf-1-area-0.0.0.0] quit
[SwitchB-ospf-1] area 2
[SwitchB-ospf-1-area-0.0.0.2] network 10.3.1.0 0.0.0.255
[SwitchB-ospf-1-area-0.0.0.2] quit
[SwitchB-ospf-1] quit

配置 Switch C。
<SwitchC> system-view
[SwitchC] router id 10.4.1.1
[SwitchC] ospf
[SwitchC-ospf-1] area 1
[SwitchC-ospf-1-area-0.0.0.1] network 10.2.1.0 0.0.0.255
[SwitchC-ospf-1-area-0.0.0.1] network 10.4.1.0 0.0.0.255
[SwitchC-ospf-1-area-0.0.0.1] quit
[SwitchC-ospf-1] quit

配置 Switch D。
<SwitchD> system-view
[SwitchD] router id 10.5.1.1
[SwitchD] ospf
[SwitchD-ospf-1] area 2
[SwitchD-ospf-1-area-0.0.0.2] network 10.3.1.0 0.0.0.255
[SwitchD-ospf-1-area-0.0.0.2] network 10.5.1.0 0.0.0.255
[SwitchD-ospf-1-area-0.0.0.2] quit
[SwitchD-ospf-1] quit

4. Verify the configuration
   (1) OSPF neighbor information on Switch A.
   [SwitchA] display ospf peer verbose
   Results As shown in FIG.
   

(2) check the OSPF routing information on Switch A.
[SwitchA] display ospf routing

(3) Switch D to view OSPF routing information.
[SwitchD] OSPF routing the display

(. 4) used in the Switch D Ping test the connectivity.
[SwitchD] ping 10.4.1.1
