1、一、搭建本次实验的拓扑结构一台高速转发交换机、二台路由器
2、二、配置本次实验的接口信息[Huawei]sysname R1[R1]interface 蘅荫酸圉GigabitEthernet 0/0/1[R1-Gi爿讥旌护gabitEthernet0/0/1]ip address 10.0.12.1 24[R1-GigabitEthernet0/0/1]quit[R1]interface loopback 0[R1-LoopBack0]ip address 10.0.1.1 32[R1-LoopBack0]quit[Huawei]sysname R2[R2]interface GigabitEthernet 0/0/1[R2-GigabitEthernet0/0/1]ip address 10.0.12.2 24[R2-GigabitEthernet0/0/1]quit[R2]interface loopback 0[R2-LoopBack0]ip address 10.0.2.2 32[R2-LoopBack0]quit
3、三、配置OSPF信息[R1]ospf 1[R1-ospf-1]area 0[R1-ospf-1-area-0.0.0.0]network 10.0.12.0 0.0.0.255[R1-ospf-1-area-0.0.0.0]network 10.0.1.1 0.0.0.0[R1-ospf-1-area-0.0.0.0]quit[R1-ospf-1]quit[R2]ospf 1[R2-ospf-1]area 0[R2-ospf-1-area-0.0.0.0]network 10.0.12.0 0.0.0.255[R2-ospf-1-area-0.0.0.0]network 10.0.2.2 0.0.0.0[R2-ospf-1-area-0.0.0.0]quit[R2-ospf-1]quit图示如下，显示的是OSPF配置后的状态信息
4、四、配置BFD的session[R1]bfd[R1-bfd]quit[R1]ospf 1[R1-ospf-1]bfd all-interfaces enable [R1-ospf-1]quit[R2]bfd[R2-bfd]quit[R2]ospf 1[R2-ospf-1]bfd all-interfaces enable[R2-ospf-1]quit
5、五、观察B掂迎豢畦FD session的状态[R1]dis bfd se all-----------------------------------幻腾寂埒---------------------------------------------Local Remote PeerIpAddr State Type InterfaceName --------------------------------------------------------------------------------8192 8192 10.0.12.2 Up D_IP_IF GigabitEthernet0/0/1 -------------------------------------------------------------------------------- Total UP/DOWN Session Number : 1/0[R2]dis bfd se all--------------------------------------------------------------------------------Local Remote PeerIpAddr State Type InterfaceName --------------------------------------------------------------------------------8192 8192 10.0.12.1 Up D_IP_IF GigabitEthernet0/0/1 -------------------------------------------------------------------------------- Total UP/DOWN Session Number : 1/0
6、六、关闭R2的接口，观察BFD与OSPF的信息[R2]interface GigabitEthernet 0/0/1[R2-GigabitEthernet0/0/1]shutdown
7、七、开启R1的接口，观察BFD状态信息[R2]interface GigabitEthernet 0/0/1[R2-GigabitEthernet0/0/1]undo shutdown[R2]dis ospf bfd se all OSPF Process 1 with Router ID 10.0.12.2 Area 0.0.0.0 interface 10.0.12.2(GigabitEthernet0/0/1)'s BFD SessionsNeighborId:10.0.12.1 AreaId:0.0.0.0 Interface:GigabitEthernet0/0/1BFDState:up rx :1000 tx :1000 Multiplier:3 BFD Local Dis:8194 LocalIpAdd:10.0.12.2RemoteIpAdd:10.0.12.1 Diagnostic Info:No diagnostic information
