实验13 ospf协议

实验13 ospf协议 一实验拓扑图二实验目的1、起用ospf协议，进程号100 2、启用认证 md53、用r2做DR，r3做BDR 4、设r1的cost值为50r2: en config t int e0 ip add 1.1.1.2 255.255.255.0 no shut int loop 1 ip add 2.2.2.2 255.255.255.0exitr3: en config t int e0 ip add 1.1.1.3 255.255.255.0 int loop 1 ip add 3.3.3.3 255.255.255.0 exit三实验命令 r1： en config t int e0 ip add 1.1.1.1 255.255.255.0 no shut int loop 1 ip add 4.4.4.4 255.255.255.0 exit 启用ospf协议： r1: config t router ospf 100 net 1.1.1.1 0.0.0.0 area 0 net 4.4.4.0 0.0.0.255 area0 exit r2: config t router ospf 100 net 1.1.1.2 0.0.0.0 area 0 net 2.2.2.0 0.0.0.255 area 0 exit r3: config t router ospf 100 net 1.1.1.3 0.0.0.0 area 0 net 3.3.3.3 0.0.0.255 area 0 exit 启用md5认证 r1：config t router ospf 100 area 0 authentication message-digest int e0 ip ospf message-digest-key 1 md5 cisco r2：config t router ospf 100 area 0 authentication message-digest int e0 ip ospf message-digest-key 1 md5 ciscor3：config t router ospf 100 area 0 authentication message-digest int e0 ip ospf message-digest-key 1 md5 cisco 设置r2为DR，设置r3为BDR r2 ； config t int e0 ip ospf priority 100 exit r3: config t int e0 ip ospf priority 50 设置r1的cost值为50 r1: config t int e0 ip ospf cost 50exit 第 2 页 共 2 页
