CCNP官方教材强调是0，实际上无论使用出站接口配置或使用下一跳地址配置的由管理距离都为1.实验如下： R1(config)#ip route 1.0.0.0 255.0.0.0 serial 0/0 R1(config)#do sh ip rou 1.0.0.0 Routing entry for 2.22.0.0/16 Known via "static", distance 1, metric 0 (connected) Routing Descriptor Blocks: * 1.1.1.2 Route metric is 0, traffic share count is 1 directly connected, via Serial0/0 Route metric is 0, traffic share count is 1 R2(config)#ip route 2.0.0.0 255.0.0.0 serial 0/0 R2(config)#ip route 2.0.0.0 255.0.0.0 1.1.1.2 R2(config)#do sh ip rou 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 Gateway of last resort is not set C 1.0.0.0/8 is directly connected, Serial0/0 2.0.0.0/8 is variably subnetted, 2 subnets, 2 masksS 2.0.0.0/8 [1/0] via 1.1.1.2 is directly connected, Serial0/0 本文出自 “辛－碌－力－成” 博客，请务必保留此出处http://orzorz.blog.51cto.com/4228156/756844 |
