（十）浮动路由和BFD配置

1.配置路由器router

system-view

sysname router

interface gigabitethernet 0/0/0

ip address 192.168.10.254 24

interface gigabitethernet 0/0/1

ip address 192.168.20.254 24

interface gigabitethernet 0/0/2

ip address 12.1.1.1 30

interface gigabitethernet 4/0/0

ip address 13.1.1.1 30

quit

// display ip interface brief

acl 2000 

rule 10 permit source 192.168.10.0 0.0.0.255

rule 20 permit source 192.168.20.0 0.0.0.255

quit

interface gigabitethernet 0/0/2

nat outbound 2000

interface gigabitethernet  4/0/0

nat outbound 2000

quit

ip route-static 0.0.0.0 0 12.1.1.2

ip route-static 0.0.0.0 0 13.1.1.2

//dispaly ip routing-table

ip route-static 0.0.0.0 0 13.1.1.2 preference 100 //优先级调大，优先级越小越优先

//tracet 22.22.22.22  查看路径

2.配置路由器dianxin

system-view

sysname dianxin 

interface gigabitethernet 0/0/0

ip address 12.1.1.2 30

interface gigabitethernet 0/0/1

ip address 100.1.1.1 30

quit

ospf 1

area 0

network 0.0.0.0.0.0.0.0

quit

//display ospf peer beief

3.配置路由器liantong 

syystem-view

sysname liantong

interface gigabitethernet 0/0/0

ip address 13.1.1.2 30

interface gigabitethernet 0/0/1

ip address 200.1.1.1 30

quit

ospf 1 //配置ospf

area 0

network 0.0.0.0.0.0.0.0

quit

4.配置互联网

system-view

sysname hulianwang

interface gigabitethernet 0/0/0

ip address 100.1.1.2 30

interface gigabitethernet 0/0/1

ip address 200.1.1.2 30

quit

interface loopback 0  //环回口

ip address 22.22.22.22 32

quit

ospf 1

area 0

network 0.0.0.0.0.0.0.0

quit

5.BFD应用

 

 router到带dianxin的优先级高于liantong，router到dainxin间加一个交换机，中断交换机到dianxin段，router还会优先走交换机

6.配置router

system-view

bfd

quit

bfd 1 bind peer-ip 12.1.1.2 source-ip 12.1.1.1 auto

commit

//跟踪路由

ip rout-staic 0.0.0.0 0 12.1.1.2 track bfd-session 1

7.配置dianxin

system-view

bfd 

quit

bfd 1 bind peer-ip 12.1.1.1 source-ip 12.1.1.2 auto 

commit

//display bfd session all
