驗(yàn)證使用出站接口配置的靜態(tài)路由管理距離

CCNP官方教材強(qiáng)調(diào)是0，實(shí)際上無(wú)論使用出站接口配置或使用下一跳地址配置的由管理距離都為1.實(shí)驗(yàn)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 masks
S       2.0.0.0/8 [1/0] via 1.1.1.2
                  is directly connected, Serial0/0
