# BFD和静态路由
|
||
|
||
|
||
|
||
### 一、配IP
|
||
|
||
- **AR1**
|
||
|
||
```
|
||
[AR1]int g0/0/2
|
||
[AR1-GigabitEthernet0/0/2]ip add 192.168.1.254 24
|
||
[AR1-GigabitEthernet0/0/2]int g0/0/0
|
||
[AR1-GigabitEthernet0/0/0]ip add 192.168.12.1 24
|
||
[AR1-GigabitEthernet0/0/0]int g0/0/1
|
||
[AR1-GigabitEthernet0/0/1]ip add 192.168.13.1 24
|
||
[AR1-GigabitEthernet0/0/1]quit
|
||
|
||
[AR1]ip route-static 192.168.2.0 24 192.168.12.2
|
||
[AR1]ip route-static 192.168.2.0 24 192.168.13.3 preference 100
|
||
```
|
||
|
||
- **AR2**
|
||
|
||
```
|
||
[AR2]int g0/0/0
|
||
[AR2-GigabitEthernet0/0/0]ip add 192.168.12.2 24
|
||
[AR2-GigabitEthernet0/0/0]int g0/0/1
|
||
[AR2-GigabitEthernet0/0/1]ip add 192.168.24.2 24
|
||
[AR2-GigabitEthernet0/0/1]quit
|
||
|
||
[AR2]ip route-static 192.168.1.0 24 192.168.12.1
|
||
[AR2]ip route-static 192.168.2.0 24 192.168.24.4
|
||
```
|
||
|
||
- **AR3**
|
||
|
||
```
|
||
[AR3]int g0/0/0
|
||
[AR3-GigabitEthernet0/0/0]ip add 192.168.13.3 24
|
||
[AR3-GigabitEthernet0/0/0]int g0/0/1
|
||
[AR3-GigabitEthernet0/0/1]ip add 192.168.34.3 24
|
||
[AR3-GigabitEthernet0/0/1]quit
|
||
|
||
[AR3]ip route-static 192.168.1.0 24 192.168.13.1
|
||
[AR3]ip route-static 192.168.2.0 24 192.168.34.4
|
||
```
|
||
|
||
- **AR4**
|
||
|
||
```
|
||
[AR4]int g0/0/0
|
||
[AR4-GigabitEthernet0/0/0]ip add 192.168.24.4 24
|
||
[AR4-GigabitEthernet0/0/0]int g0/0/1
|
||
[AR4-GigabitEthernet0/0/1]ip add 192.168.34.4 24
|
||
[AR4-GigabitEthernet0/0/1]int g0/0/2
|
||
[AR4-GigabitEthernet0/0/2]ip add 192.168.2.254 24
|
||
[AR4-GigabitEthernet0/0/2]quit
|
||
|
||
[AR4]ip route-static 192.168.1.0 24 192.168.24.2
|
||
[AR4]ip route-static 192.168.1.0 24 192.168.34.3 preference 100
|
||
```
|
||
|
||
### 二、BFD
|
||
|
||
- **AR1**
|
||
|
||
```
|
||
[AR1]ip route-static 192.168.24.0 24 192.168.12.2
|
||
[AR1]ip route-static 192.168.34.0 24 192.168.13.3
|
||
|
||
[AR1]bfd
|
||
[AR1-bfd]quit
|
||
[AR1]bfd ntd2407 bind peer-ip 192.168.24.4
|
||
[AR1-bfd-session-ntd2407]discriminator local 1
|
||
[AR1-bfd-session-ntd2407]discriminator remote 4
|
||
[AR1-bfd-session-ntd2407]min-tx-interval 10
|

|
||
[AR1-bfd-session-ntd2407]quit
|
||
|
||
[AR1]ip route-static 192.168.2.0 24 192.168.12.2 track bfd-session ntd2407
|
||
```
|
||
|
||
- *注解：*
|
||
1. `[AR1]bfd`：进入BFD配置模式
|
||
2. `[AR1-bfd]quit`：退出BFD配置模式
|
||
3. `[AR1]bfd ntd2407 bind peer-ip 192.168.24.4`：创建一个名为`ntd2407`的BFD会话，并将其绑定到对端IP地址`192.168.24.4`
|
||
4. `[AR1-bfd-session-ntd2407]discriminator local 1`：为本地设备设置BFD会话的鉴别器值为`1`
|
||
5. `[AR1-bfd-session-ntd2407]discriminator remote 4`：设置对端设备BFD会话的鉴别器值为`4`
|
||
6. `[AR1-bfd-session-ntd2407]min-tx-interval 10`：设置BFD会话的最小发送间隔为`10`毫秒
|
||
7. `[AR1-bfd-session-ntd2407]min-rx-interval 10`：设置BFD会话的最小接收间隔为`10`毫秒
|
||
8. `[AR1-bfd-session-ntd2407]commit`：提交BFD会话的配置，使其生效
|
||
9. `ip route-static 192.168.2.0 24 192.168.12.2 track bfd-session ntd2407`：BFD与静态路由联动
|
||
|
||
- **AR4**
|
||
|
||
```
|
||
[AR4]ip route-static 192.168.12.0 24 192.168.24.2
|

|
||
3. `[AR1]bfd ntd2407 bind peer-ip 192.168.12.1`：创建一个名为`ntd2407`的BFD会话，并将其绑定到对端IP地址`192.168.12.1`
|
||
4. `[AR1-bfd-session-ntd2407]discriminator local 4`：为本地设备设置BFD会话的鉴别器值为`4`
