测试步骤和结果： 步骤 14:需要将 L2 路由器的 192.168.0.0 的路由泄露给 L1 路由器，写 access-list 匹配感兴趣路由再将路 由由 L2 into L1 在 L2L1 路由器上做配置： access-list 100 permit ip 192.168.0.0 0.0.255.255 any router isis bluefox redistribute isis ip level-2 into level-1 distribute-list 100 步骤15:查看路由表 R1#show ip route Codes: C - connected, S - static, R - RIP, M - mobile, B - BGP D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2 E1 - OSPF external type 1, E2 - OSPF external type 2 i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2 ia - IS-IS inter area, * - candidate default, U - per-user static route o - ODR, P - periodic downloaded static route
