步驟五.OSPF認(rèn)證配置及驗(yàn)證
將R1接口S1/0/0配置為OSPF接口認(rèn)證模式、明文、密碼“Huawei”。
[R1]interface s1/0/0
[R1-Serial1/0/0]ospf auth
[R1-Serial1/0/0]ospf authentication-mode simple plain huawei
[R1]display ospf peer brief
OSPF Process 1 with Router ID 10.0.1.1
Peer Statistic Information
----------------------------------------------------------------------------
Area Id Interface Neighbor id State
0.0.0.1 GigabitEthernet0/0/0 10.0.3.3 Full
----------------------------------------------------------------------------
[R1]
此時R1與R2的ospf認(rèn)證方式不匹配,所以R1與R2無法建立鄰居。
將R2接口S1/0/0配置為OSPF接口認(rèn)證模式,明文,密碼“Huawei”。
[R2]interface ser1/0/0
[R2-Serial1/0/0]ospf auth
[R2-Serial1/0/0]ospf authentication-mode simple plain huawei
在R1查看與R2的鄰居狀態(tài)。
[R1]display ospf peer brief

Area Id Interface Neighbor id State

0.0.0.1 GigabitEthernet0/0/0 10.0.3.3 Full
----------------------------------------------------------------------------
[R1]
此時R1、與R2之間認(rèn)證方式和密碼均匹配,所以R1與R2重新建立了鄰居關(guān)系。將R1的區(qū)域配置為OSPF區(qū)域認(rèn)證模式,加密方式為MD5,密碼問密文形式“Huawei”。
[R1]ospf 1
[R1-ospf-1]area 1
[R1-ospf-1-area-0.0.0.1]authentication-mode md5 1 cipher Huawei
在R1上查看與R3的鄰居狀態(tài)。
[R1]display ospf peer brief

----------------------------------------------------------------------------

----------------------------------------------------------------------------
[R1]
由于R1與R3之間OSPF認(rèn)證方式不匹配,此時R1與R3無法建立鄰居關(guān)系。
將R3上區(qū)域1配置為OSPF區(qū)域認(rèn)證模式,加密方式為MD5,密碼為密文形式“Huawei”。
[R3]ospf
[R3-ospf-1]area 1
[R3-ospf-1-area-0.0.0.1]authentication-mode md5 1 cipher huawei
在R1上查看與R3的鄰居狀態(tài)。

此時R1與R3之間認(rèn)證方式和密碼均匹配,所以R1與R3重新建立了鄰居關(guān)系。
