任务 4：配置基于出站接口的静态路由
步骤 1：在 R2 上创建一条到 192.168.3.0/24 的路由，以 Fa0/0.23 为出站接口
R2(config)#ip route 192.168.3.0 255.255.255.0 fastEthernet 0/0.23
步骤 2：检查 R2 的路由表，会看到一条到 192.168.3.0/24 的静态路由
R2#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 not set C 192.168.12.0/24 is directly connected, FastEthernet0/0.12 C 192.168.24.0/24 is directly connected, FastEthernet0/0.24 C 192.168.23.0/24 is directly connected, FastEthernet0/0.23 S 192.168.1.0/24 [1/0] via 192.168.12.1 S 192.168.3.0/24 is directly connected, FastEthernet0/0.23
步骤 3：再配置一条到 192.168.4.0/24 的静态路由，以 fa0/0.24 为出站接口
R2(config)#ip route 192.168.4.0 255.255.255.0 fastEthernet 0/0.24
步骤 4：检查 R2 的路由表，到目前为止，R2 已经获得了所有网络的路由（3 个直连网络和到 3 个 Loopback0 的静态路由）
R2#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 not set C 192.168.12.0/24 is directly connected, FastEthernet0/0.12 C 192.168.24.0/24 is directly connected, FastEthernet0/0.24 S 192.168.4.0/24 is directly connected, FastEthernet0/0.24 C 192.168.23.0/24 is directly connected, FastEthernet0/0.23 S 192.168.1.0/24 [1/0] via 192.168.12.1 S 192.168.3.0/24 is directly connected, FastEthernet0/0.23 R2#
