ospf实验

ospf实验

第一步：地址划分

分析得骨干链路需要4段

环回地址需要5段

第二步：测试连通性

第四步：查看路由表

<ar1>display ip routing-table protocol ospf

Route Flags: R - relay, D - download to fib

Public routing table : OSPF Destinations : 7 Routes : 7

OSPF routing table status : <Active> Destinations : 7 Routes : 7

Destination/Mask Proto Pre Cost Flags NextHop Interface

 172.16.0.0/25  OSPF    10   49          D   172.16.0.130    Serial4/0/0

OSPF routing table status : <Inactive> Destinations : 0 Routes : 0

第五步：测试连通性

--- 172.16.4.1 ping statistics --- 5 packet(s) transmitted 5 packet(s) received 0.00% packet loss round-trip min/avg/max = 40/56/80 ms

第六步：改变dr与bdr的进选

第七步：认证

r3与r4之间明文认证

[Huawei-Serial4/0/0]ospf authentication-mode simple cipher sb

[Huawei-Serial4/0/0]ospf authentication-mode simple cipher sb

r4与r5密文认证

[Huawei-Serial4/0/1]ospf authentication-mode md5 1 123456 [Huawei-Serial4/0/0]ospf authentication-mode md5 1 123456

第八步：设置r3的环回

[R3jinterface LoopBack 100[R3-LoopBack100]ip add[R3-LoopBack100]q R3110 rou [R3-LoopBack1001ip address 100.1.1.1 24 [R3]ip route [R3]ip route-static 0.0.0.0 0 10 R3 Jip route-static 0.0.0.0 0 LoopBack 100 [R3lospf 1 rou [R3-ospf-1]de[R3-ospf-1]default[R3-ospf-1]■ [R3-ospf-11default-route-advertise
