华为设备配置静态BFD for IS-IS特性

本文主要是介绍华为设备配置静态BFD for IS-IS特性，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

1. 配置各接口所属VLAN
   [LSW1]vlan 10
   [LSW1-GigabitEthernet0/0/1]port link-type trunk
   [LSW1-GigabitEthernet0/0/1]port trunk allow-pass vlan 10
   [LSW2]vlan batch 10 20
   [LSW2-GigabitEthernet0/0/1]port link-type trunk
   [LSW2-GigabitEthernet0/0/1]port trunk allow-pass vlan 10
   [LSW2-GigabitEthernet0/0/2]port link-type trunk
   [LSW2-GigabitEthernet0/0/2]port trunk allow-pass vlan 20
   [LSW3]vlan 20
   [LSW3-GigabitEthernet0/0/1]port link-type trunk
   [LSW3-GigabitEthernet0/0/1]port trunk allow-pass vlan 20
   [LSW4]vlan batch 10
   [LSW4-Ethernet0/0/1]port link-type trunk
   [LSW4-Ethernet0/0/1]port trunk allow-pass vlan 10
   [LSW4-Ethernet0/0/2]port link-type trunk
   [LSW4-Ethernet0/0/2]port trunk allow-pass vlan 10

2. 配置各交换机VLANIF接口的IP地址
   [LSW1-Vlanif10]ip add 10.1.1.1 24
   [LSW2-Vlanif10]ip add 10.1.1.2 24
   [LSW2-Vlanif20]ip add 10.2.1.2 24
   [LSW3-Vlanif20]ip add 10.2.1.3 24

3. 配置IS-IS基本功能
   [LSW1]isis 1
   [LSW1-isis-1]is-level level-2
   [LSW1-isis-1]network-entity 10.1111.1111.1111.00
   [LSW1-Vlanif10]isis enable
   [LSW2]isis 1
   [LSW2-isis-1]is-level level-2
   [LSW2-isis-1]network-entity 10.2222.2222.2222.00
   [LSW2-Vlanif10]isis enable
   [LSW2-Vlanif20]isis enable 1
   [LSW3]isis 1
   [LSW3-isis-1]is-level level-2
   [LSW3-isis-1]network-entity 10.3333.3333.3333.00
   [LSW3-Vlanif20]isis enable 1
   
   

4. 配置BFD
   [LSW1]bfd
   [LSW1]bfd 1to2 bind peer-ip 10.1.1.2 interface Vlanif 10
   [LSW1-bfd-session-1to2]discriminator local 1
   [LSW1-bfd-session-1to2]discriminator remote 2
   [LSW1-bfd-session-1to2]commit
   [LSW2]bfd
   [LSW2]bfd 2to1 bind peer-ip 10.1.1.1 interface Vlanif 10
   [LSW2-bfd-session-2to1]discriminator local 2
   [LSW2-bfd-session-2to1]discriminator remote 1
   [LSW2-bfd-session-2to1]commit
   

5. 使能IS-IS的快速感知特性
   [LSW1-Vlanif10]isis bfd static
   [LSW2-Vlanif10]isis bfd static

6. 检查配置
   （1）打开LSW1调试信息开关，使信息输出到VTY通道
   [LSW1]info-center source bfd channel 1 log level debugging state on
   debugging isis circuit-information
   terminal debugging
   terminal logging
   terminal monitor
   （2）关闭LSW2的g0/0/1，模拟链路故障，LSW1显示以下日志信息和调试信息
   [LSW2-GigabitEthernet0/0/1]shutdown
