第三十三课 浮动路由+BFD双向链路检测设置案例

实验目的：

1、 了解浮动路由的配置方法

2、 掌握BFD的配置方法

网络拓扑如下：

实验配置如下：

交换机SW1的配置如下：

sysname SW1

#

vlan batch 10 20 40

#

stp disable //因为由环路需关闭生成树功能，不然SW2的GE0/0/1将阻塞掉，无法学习到192.168.30.0地址

#

bfd //全局模式下开启bfd

#

interface Vlanif10

ip address 192.168.10.254 255.255.255.0

#

interface Vlanif20

ip address 192.168.20.1 255.255.255.0

#

interface Vlanif40

ip address 192.168.40.1 255.255.255.0

#

interface GigabitEthernet0/0/1

port link-type trunk

port trunk allow-pass vlan 40

#

interface GigabitEthernet0/0/2

port link-type trunk

port trunk allow-pass vlan 20

#

interface GigabitEthernet0/0/3

port link-type access

port default vlan 10

#

bfd sw20 bind peer-ip 192.168.20.2 //进入bfd,取名为sw20并绑定对端交换机地址

discriminator local 1 //辨别本地标识为1

discriminator remote 2 //辨别远端标识为2

commit //提交配置

#

ip route-static 192.168.30.0 255.255.255.0 192.168.20.2 track bfd-session sw20

ip route-static 192.168.30.0 255.255.255.0 192.168.40.2 preference 80

交换机SW2的配置如下：

sysname SW2

#

vlan batch 20 30 40

#

stp disable //因为由环路需关闭生成树功能，不然SW2的GE0/0/1将阻塞掉，无法学习到192.168.10.0地址

#

Bfd //全局模式下开启bfd

#

interface Vlanif20

ip address 192.168.20.2 255.255.255.0

#

interface Vlanif30

ip address 192.168.30.254 255.255.255.0

#

interface Vlanif40

ip address 192.168.40.2 255.255.255.0

#

interface GigabitEthernet0/0/1

port link-type trunk

port trunk allow-pass vlan 20

#

interface GigabitEthernet0/0/2

port link-type trunk

port trunk allow-pass vlan 40

#

interface GigabitEthernet0/0/3

port link-type access

port default vlan 30

#

bfd sw20 bind peer-ip 192.168.20.1 //进入bfd,取名为sw20并绑定对端交换机地址

discriminator local 2 //辨别本地标识为2

discriminator remote 1 //辨别远端标识为1

commit //提交配置

#

ip route-static 192.168.10.0 255.255.255.0 192.168.20.1 track bfd-session sw20

ip route-static 192.168.10.0 255.255.255.0 192.168.40.1 preference 80

#

交换机SW2的配置如下：

sysname SW3

#

vlan batch 40

#

interface GigabitEthernet0/0/1

port link-type trunk

port trunk allow-pass vlan 40

#

interface GigabitEthernet0/0/2

port link-type trunk

port trunk allow-pass vlan 40
