默认路由试验(二)

RIP

  

P1R1配置： 

P1R1(config)#ip route 0.0.0.0 0.0.0.0 172.31.1.2 创建一条静态路由

也可以 ip route 0.0.0.0 0.0.0.0 s1/0

这样的话 P1R1路由表出现的

Gateway of last resort is 0.0.0.0 to network 0.0.0.0

P1R1(config)#router rip 

P1R1(config-router)#default-information originate 通过RIP协议通告默认路由！ 

P1R1路由表： 

P1R1#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

 

Gateway of last resort is 172.31.1.2 to network 0.0.0.0

 

     172.31.0.0/16 is variably subnetted, 2 subnets, 2 masks

C       172.31.1.0/24 is directly connected, Serial1/0

R       172.31.0.0/16 [120/1] via 10.1.0.2, 00:00:08, Serial1/1

     10.0.0.0/24 is subnetted, 3 subnets

R       10.1.2.0 [120/1] via 10.1.0.2, 00:00:08, Serial1/1

C       10.1.1.0 is directly connected, FastEthernet0/0

C       10.1.0.0 is directly connected, Serial1/1

S*   0.0.0.0/0 [1/0] via 172.31.1.2
