#

ip route-static 0.0.0.0 0.0.0.0 100.1.1.2

AR4配置：

acl number 2000

rule 5 permit source 192.168.0.0 0.0.255.255

interface GigabitEthernet0/0/0

ip address 200.1.1.2 255.255.255.252

#

interface GigabitEthernet0/0/2

ip address 10.1.1.2 255.255.255.252

#

ospf 1

default-route-advertise

area 0.0.0.0

network 10.1.1.0 0.0.0.3

network 192.168.33.0 0.0.0.255

#

ip route-static 0.0.0.0 0.0.0.0 200.1.1.1

关闭STP核心交换机上联接口（对接路由器）

int gi 0/0/X

stp disable(关闭STP计算接口会收敛更快）

OSPF中一定要宣告 route-ID 1.1.1.1 2.2.2.2 3.3.3.3 由这些来触发心跳hello报文

int look 0

ip add 1.1.1.1 24
