CCNP Day4 EIGRP默认路由
1、配置拓扑（在R3上添加一条默认路由）
R3(config)#ip router 0.0.0.0 0.0.0.0 loopback 0 /**第一种配置方法**/
R3(config)#do 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 0.0.0.0 to network 0.0.0.0 1.0.0.0/24 is subnetted, 1 subnets D 1.1.1.0 [90/2300416] via 192.168.23.1, 00:35:14, Serial1/0 3.0.0.0/24 is subnetted, 1 subnets C 3.3.3.0 is directly connected, Loopback0 172.16.0.0/24 is subnetted, 1 subnets D 172.16.12.0 [90/2172416] via 192.168.23.1, 00:35:18, Serial1/0 C 192.168.23.0/24 is directly connected, Serial1/0 S* 0.0.0.0/0 is directly connected, Loopback0 /**默认路由带*号**/ R3(config)#
2、把默认路由宣告到Eigrp
R3(config)#router eigrp 100 R3(config-router)#network 0.0.0.0 R3(config-router)#end R3#show ip rou *Nov 25 11:02:34.911: %SYS-5-CONFIG_I: Configured from console by console R3#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 0.0.0.0 to network 0.0.0.0 1.0.0.0/24 is subnetted, 1 subnets D 1.1.1.0 [90/2300416] via 192.168.23.1, 00:39:32, Serial1/0 3.0.0.0/24 is subnetted, 1 subnets C 3.3.3.0 is directly connected, Loopback0 172.16.0.0/24 is subnetted, 1 subnets D 172.16.12.0 [90/2172416] via 192.168.23.1, 00:39:36, Serial1/0 C 192.168.23.0/24 is directly connected, Serial1/0 S* 0.0.0.0/0 is directly connected, Loopback0 R3#
3、在R1和R2上查看路由
