华为ospf多区域配置
OSPF多区域配置
1.规划网络拓扑图如下：
文字说明：
a.R1与R2作为末梢区域area1
b.R2与R3作为主区域area0
c.R3与R4作为末梢区域area2
d.R1上连接交换机LSW3，LSW3上拥有vlan8，g0/0/1与g/0/2属于vlan8
e.R1还直连一个主机，网段为网段。
2.配置：

查看R2的路由表：
3.配置R1与R2链路认证，使用明文认证
R1：
[R1]inte0/0/0
[R1-Ethernet0/0/0]ospfaut
[R1-Ethernet0/0/0]ospfauthentication-modesim
[R1-Ethernet0/0/0]ospfauthentication-modesimpleplainYP
[R1-Ethernet0/0/0]q
查看邻居路由：
两个路由器链路密码不同断开认证邻居关系

R2：
[R2]inte0/0/0
[R2-Ethernet0/0/0]ospfau
[R2-Ethernet0/0/0]ospfauthentication-modesimpleplainYP
[R2-Ethernet0/0/0]q
查看邻居路由：

4.配置R3与R4的区域认证，使用密文认证。

其实只要是两个不同的区域都能作区域认证和链路认证。
