Static route configuration instance learning record

Static route configuration instance

Routes set manually are called static routes , Static routing is fixed , It will not change automatically with the change of network topology

---

---

1、 The goal of the experiment

Learn how to configure static routes , Understand the characteristics of router hop by hop forwarding .

---

2、 Network topology

---

3、 Configuration steps

（1） Configure ports by topology IP Address

R1 To configure ：

<R1>system-view  // Enter the system view 
[R1]interface GigabitEthernet0/0/0
[R1-GigabitEthernet0/0/0]ip address 10.1.1.1 24  // configure port  IP  Address （IP  Address : 10.1.1.1  Subnet mask : 24）
[R1-GigabitEthernet0/0/0]quit
[R1]interface Ethernet0/0/1
[R1-Ethernet0/0/1]ip address 192.168.10.1 24  // configure port  IP  Address （IP  Address : 192.168.10.1  Subnet mask : 24）
[R1-Ethernet0/0/1]quit

R2 To configure ：

<R2>system-view  // Enter the system view 
[R2]interface GigabitEthernet0/0/0
[R2-GigabitEthernet0/0/0]ip address 10.1.1.2 24  // configure port  IP  Address （IP  Address : 10.1.1.2  Subnet mask : 24）
[R2-GigabitEthernet0/0/0]quit	
[R2]interface Ethernet0/0/1
[R2-Ethernet0/0/1]ip address 192.168.20.1 24  // configure port  IP  Address （IP  Address : 192.168.20.1  Subnet mask : 24）
[R2-Ethernet0/0/1]quit

（2） Configure static routing

R1 To configure ：

[R1]ip route-static 192.168.20.0 24 10.1.1.2  //ip route-static [ Destination address segment ] [ Destination address subnet mask ] [ Next jump  IP  Address ]

R2 To configure ：

[R2]ip route-static 192.168.10.0 24 10.1.1.1  //ip route-static [ Destination address segment ] [ Destination address subnet mask ] [ Next jump  IP  Address ]

4、 test

（1） View the established route entries , Static routing... Look

Tips ： Use display ip routing-table Command to view the routing table

see R1 Routing table ：

[R1]display ip routing-table  // View routing table

5、 Summary

Configuring static routing is mainly to understand the concept of target address network segment and next hop .

In the routing table , Static routing Proto The field is displayed as Static, By default , Routing priority Pre by 60, The routing overhead is 0.

Advantages of static routing ： It does not occupy network bandwidth and system resources , Security .
Disadvantages of static routing ： When a failure occurs in the network , Static routing doesn't automatically fix , It must be manually configured one by one by the network administrator , It cannot automatically make corresponding adjustments according to the changes of network status .
