路由器交换机配置BFD与OSPF联动实验

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 GigabitEthernet 0/0/1[R1-GigabitEthernet0/0/1]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BFD session的状态

[R1]dis bfd se all--------------------------------------------------------------------------------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 Sessions
