OSPF
如图所示,配置设备名称和IP地址
a) 设备Ra与设备Rb之间的互联地址按照192.168.ab.a/24和192.168.ab.b/24的方式规划(a<B)
如R3与R4互联地址为192.168.34.3/24和192.168.34.4/24,以此类推。
a) 每台设备都有环回口Loopback0,设备Ra的地址为a.a.a.a/32
如R1就有Lo0:1.1.1.1/32
在所有路由器上运行OSPF,满足以下需求:
a) OSPF进程号为1,RID手动设置为Lo0地址。
b) 如图所示划分OSPF区域,network命令使用接口配置掩码的反掩码。
c) ABR的环回口宣告到区域0中。
d) 在R2 R3 R4的邻居关系中,设置R3为DR,并且R2与R4保持2way状态。
e) 区域1中使用区域md5验证,key-id为1,口令为“spoto”(不含引号),且使用display命令可以查看到口令。
f) R4与R5使用接口明文验证,口令为“huawei”(不含引号),且使用display命令无法查看到明文口令。
