实验名称：作OSPF的3类5类汇总 实验拓扑

实验步骤： 配置ip

R1： enable conf t int f 0/0 no shu ip add 192.168.12.1 255.255.255.0 exit int l 0 ip add 10.10.1.1 255.255.255.0 exit

R2: enable conf t int f 0/1 no shu ip add 192.168.12.2 255.255.255.0 exit int l 0 ip add 10.10.2.2 255.255.255.0 exit int f0/0 no shu ip add 192.168.23.2 255.255.255.0 exit

R3: enable conf t int f0/1 no shu ip add 192.168.23.3 255.255.255.0 exit int l 0 ip add 10.10.3.3 255.255.255.0 exit int f0/0 no shu ip add 192.168.34.3 255.255.255.0 exit

R4: enable conf t int f0/1 no shu ip add 192.168.34.4 255.255.255.0 exit int l 0 ip add 10.10.4.4 255.255.255.0 exit

配置OSPF

R1： router os 1 router-id 1.1.1.1 net 192.168.12.0 0.0.0.255 ar 12 net 10.10.1.0 0.0.0.255 ar 12 exit

R2: router os 1 router-id 2.2.2.2 net 192.168.12.0 0.0.0.255 ar 12 net 192.168.23.0 0.0.0.255 ar 0 net 10.10.2.0 0.0.0.255 ar 0 exit

R3: router os 1 router-id 3.3.3.3 net 192.168.23.0 0.0.0.255 ar 0 net 192.168.34.0 0.0.0.255 ar 0 net 10.10.3.0 0.0.0.255 ar 0 exit

R4: router os 1 router-id 4.4.4.4 net 192.168.34.0 0.0.0.255 ar 0 net 10.10.4.0 0.0.0.255 ar 0 exit

做3类汇总思路先在R1作几个直连路由，在R2做汇总，在其他路由 做验证 R1： int l 11 ip add 11.11.1.1 255.255.255.0 exit int l 12 ip add 11.11.2.2 255.255.255.0 exit int l 13 ip add 11.11.3.3 255.255.255.0 exit router os 1 router-id 1.1.1.1 net 11.11.1.0 0.0.0.255 ar 12 net 11.11.2.0 0.0.0.255 ar 12 net 11.11.3.0 0.0.0.255 ar 12 exit clear ip os p y show ip route show ip os da

R2: router os 1 area 12 range 11.11.0.0 255.255.0.0 (把12区域的11.11的各 个网段汇总为11.11.0.0网段) exit clear ip os p y show ip route show ip os da

R3: clear ip os p y show ip route show ip os da show ip os

R4: clear ip os p y show ip route show ip os da show ip os show ip route os

做5类的汇总思路，先在R1做几个直连路由，静态重分发，做5类 LSA，在R1做会总，在其他路由验证

R1： int l 21 ip add 22.22.1.1 255.255.255.0 exit int l 22 ip add 22.22.2.2 255.255.255.0 exit int l 23 ip add 22.222.3.3 255.255.255.0 exit

router os 1 redistribute connected subnets (静态重分发，建5类LSA) exit router os 1 summary-address 22.22.0.0 255.255.0.0 exit clear ip os p y show ip route show ip os show ip os da

R2: clear ip os p y show ip route show ip os da

R3: clear ip os p y show ip rute os show ip os da

R4: clear ip os p y show ip rute os show ip os da
