静态路由与BFD联动（直连）

H3C静态路由默认下AD=60

拓扑见QQ收藏

正常情况下，1.1.1.1访问2.2.2.2 时数据通过S1->S2，当S1-S2的链路出现故障，快速切换到S1->S3->S2

S1配置：

[S1]vlan 10

[S1-vlan10]vlan 20

[S1]int E1/0/1

[S1-Ethernet1/0/1]port link-type access

[S1-Ethernet1/0/1]port access vlan 10

[S1-Ethernet1/0/1]int e1/0/2        

[S1-Ethernet1/0/2]port link-type access

[S1-Ethernet1/0/2]port access vlan 20 

[S1-Ethernet1/0/2]int vlan 10

[S1-Vlan-interface10]ip add 12.1.1.1 24

[S1-Vlan-interface10]int vlan 20

[S1-Vlan-interface20]ip add 13.1.1.1 24

[S1]int LoopBack 1

[S1-LoopBack1]ip add 1.1.1.1 32

[S1]ip route-static 23.1.1.0 24 13.1.1.3  没有这条路由，链路切换不过来

[S1] ip route-static 2.2.2.2 32 Vlan-interface10 12.1.1.2 bfd control-packet

[S1]ip route-static2.2.2.2 32 13.1.1.3 preference 100

[S1-Vlan-interface10]bfd min-transmit-interval 300         

[S1-Vlan-interface10]bfd min-receive-interval 300

[S1-Vlan-interface10]bfd detect-multiplier 10     注意在接口配置，不是系统视图

S2配置：

[S2]vlan 10 

[S2-vlan10]vlan 30

[S2]int e1/0/1

[S2-Ethernet1/0/1]port link-type access

[S2-Ethernet1/0/1]port access vlan 10

[S2]int e1/0/2

[S2-Ethernet1/0/2]port link-type access

[S2-Ethernet1/0/2]port access vlan 30

[S2]int vlan 10

[S2-Vlan-interface10]ip add 12.1.1.2 24

[S2-Vlan-interface10]int vlan 30

[S2-Vlan-interface30]ip add 23.1.1.2 24

[S2]int LoopBack 0

[S2-LoopBack0]ip add 2.2.2.2 32

[S2]ip route-static 13.1.1.0 24 23.1.1.3   

[S2] ip route-static1.1.1.1 32 Vlan-interface10 12.1.1.1 bfd control-packet

[S2]ip route-static1.1.1.1 32 23.1.1.3 preference 100

[S2-Vlan-interface10]bfd min-transmit-interval 300      

[S2-Vlan-interface10]bfd min-receive-interval 300

[S2-Vlan-interface10]bfd detect-multiplier 10

S3配置：

[S3]vlan 20   

[S3-vlan20]vlan 30

[S3-vlan30]int e1/0/1

[S3-Ethernet1/0/1]port link-type access

[S3-Ethernet1/0/1]port access vlan 20

[S3-Ethernet1/0/1]int e1/0/2          

[S3-Ethernet1/0/2]port link-type access

[S3-Ethernet1/0/2]port access vlan 30 

[S3]int vlan 20

[S3-Vlan-interface20]ip add 13.1.1.3 24

[S3-Vlan-interface20]int vlan 30

[S3-Vlan-interface30]ip add 23.1.1.3 24

[S3]ip route-static1.1.1.1 32 13.1.1.1

[S3]ip route-static 2.2.2.232 23.1.1.2

注意：由于用的是交换机，为了防止环路，所以有一个接口会是阻塞状态，切换的速度快慢取决于STP的模式
