R3
interface Ethernet0/1ip ospf hello-interval 11取消该时间间隔配置
interface Ethernet0/1no ip ospf hello-interval查询邻居信息, R1-R3邻居正常建立。

1.1.1.1 1 FULL/BDR 00:00:39 12.1.1.1 Ethernet0/0发现R2与R4之间的邻居不正常继续排错
错误3R2的e0/1接口区域配置不正确
重新配置
interface Ethernet0/1no ip ospf 1 area 89ip ospf 89 area 1错误4R4的e0/1接口没有配置进OSPF
配置进OSPF
interface Ethernet0/1no ip ospf 1 area 89ip ospf 89 area 1查询邻居发现依然没有建立成功。 发现area1被配置成特殊区域。
router ospf 89router-id 4.4.4.4area 1 stub错误5R2的区域1没有配置成特殊区域
将R2上的area1配置成特殊区域。
R2:router ospf 89area 1 stub邻居成功建立 检查所有的邻居关系。发现还剩下R3-R4之间的邻居关系没有起来继续排错。
错误6R4上e/0的接口并没有宣告进OSPF
配置接口进入OSPF
R4:interface Ethernet0/0ip ospf 89 area 1邻居依然没有建立。继续排错。
错误7R4-R3之间的网络类型不一致
配置R4上E0/0的网络类型 R3上E0/0的下的网络类型是配置成了point-to-point所以调整R4的E0/0的网络类型
R4:interface Ethernet0/0ip ospf network point-to-point邻居依然没有建立。继续排错。
错误8R3没有配置区域1为特殊区域
R3:router ospf 89area 1 stub成功排除错误邻居建立成功。
错误9R2上的area1的聚合路由
取消聚合路由
R2:router ospf 89no area 1 range 4.4.4.0 255.255.255.0查询R1上的路由表依然没有出现等价负载均衡。继续排错
