ISIS配置
- R1:
en conf t ip classless (子网支持） ip subnet-zero （零子网） no ip domain-lookup hostname R1 int f0/1 ip add 192.168.1.1 255.255.255.0 no sh int f0/0 ip add 200.0.0.1 255.255.255.0 no sh end show ip int brief conf t clns routing router isis net 49.0001.0000.0000.0001.00 （49是isis私有序号） exit int f0/1 ip router isis int f0/0 ip router isis end show ip route
- ISIS优化：
conf t router isis is-type level-1 （类型1） end show ip route
R2:
en conf t ip classless ip subnet-zero no ip domain-lookup hostname R2 int f0/1 ip add 200.1.1.1 255.255.255.0 no sh int f0/0 ip add 200.0.0.2 255.255.255.0 no sh end show ip int brief conf t clns routing router isis net 49.0001.0000.0000.0002.00 exit int f0/1 ip router isis int f0/0 ip router isis end show ip route
- ISIS优化：
conf t int f0/0 isis cricuit-type level-1 int f0/1 isis cricuit-type level-2-only end show ip route
- R3:
en conf t ip classless ip subnet-zero no ip domain-lookup hostname R3 int f0/1 ip add 200.1.1.2 255.255.255.0 no sh int f0/0 ip add 200.2.2.1 255.255.255.0 no sh end show ip int brief conf t clns routing router isis net 49.0002.0000.0000.0003.00 exit int f0/1 ip router isis int f0/0 ip router isis end show ip route
- ISIS优化：
conf t router isis is-type level-2-only end show ip route
- R4:
en conf t ip classless ip subnet-zero no ip domain-lookup hostname R4 int f0/1 ip add 200.3.3.1 255.255.255.0 no sh int f0/0 ip add 200.2.2.2 255.255.255.0 no sh end show ip int brief conf t clns routing router isis net 49.0003.0000.0000.0004.00 exit int f0/1 ip router isis int f0/0 ip router isis end show ip route
- ISIS优化：
conf t int f0/0 isis cricuit-type level-2-only int f0/1 isis cricuit-type level-1 end show ip route
- R5:
en conf t ip classless ip subnet-zero no ip domain-lookup hostname R5 int f0/1 ip add 200.3.3.2 255.255.255.0 no sh int f0/0 ip add 192.168.2.1 255.255.255.0 no sh end show ip int brief conf t clns routing router isis net 49.0003.0000.0000.0005.00 exit int f0/1 ip router isis int f0/0 ip router isis end show ip route
- ISIS优化：
conf t router isis is-type level-1 end show ip route
- 测试：
PC IP:192.168.1.2 PC IP:192.168.2.2
