Basic configuration of static routing to achieve network wide accessibility

Experimental content ：

How routers work ： When the packet enters the router , First check the target IP Address ; Then query the local routing table , If there are records in the table , take Unconditional Forward as recorded ; If there is no record , The traffic will be discarded .

  Through handwritten static routing, the whole network can reach .

Experimental environment ：eNSP

Experimental process ：

(1) port configuration

With routers AR1 For example ：

The instructions are as follows ：

[Huawei]interface g0/0/0    Enter an interface 
[Huawei-GigabiEthernet0/0/0]ip address 192.168.1.1 24    To configure IP Address 
[Huawei]interface g0/0/1
[Huawei-GigabiEthernet0/0/1]ip address 192.168.2.1 24
<Huawei>display ip interface brief    View the interface summary 

 AR1、AR2、 AR3 Summary of ports of three routers ：

 

  Confirm each port IP When there is no mistake , Next, configure the static routes .

（2） Static routing configuration

By default, the router targets a network segment , The non direct network segment is an unknown network segment ;

Method of obtaining unknown network segment ：

1. Static routing —— Handwriting

2. Dynamic routing —— Negotiation between routers 、 communicate 、 Calculation 、 Automatic generation

How to write static routing

The instructions are as follows ：

[Huawei]ip route-static 192.168.3.0（ Target network number ） 255.255.255.0 192.168.2.2（ Next jump ） 

Next jump ： The flow enters the next interface IP Address

View routing table  

[Huawei]display ip routing-table

Follow this operation to complete the static configuration of the three routers

 

 

  We have completed the port configuration of the router 、 Configuration of static route , The terminal also needs to be IP、 Gateway configuration , The whole network can reach .

The experimental results also need to be tested , use PC1 Go separately pingPC2、PC3.

 

 

  thus , The experiment is over , Achieve the purpose of the experiment ： Network wide accessibility .
