网络工程 - 在 GNS3 中路由网络的问题 - 吾爱随笔录

有人可以帮帮我吗：

Cloud 5 在我的 PC 上配置了一个环回适配器，ip 为 10.84.104.254。R1 F0/1：10.84.104.1

我可以从外部 ping R1 F0/1，也可以 ping 并执行从 R1 F0/0 到内部网络的所有功能。但是当我尝试从外部 ping R2 F0/0 (192.168.12.2) 时，它无法访问。

我猜路由器 R1 上的 fastethernet 端口 f0/0 和 f0/1 之间没有发生通信。

请建议：

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 10.84.104.254 to network 0.0.0.0

C    192.168.12.0/24 is directly connected, FastEthernet0/0
     192.168.14.0/32 is subnetted, 1 subnets
O       192.168.14.5 [110/41] via 192.168.12.2, 00:12:56, FastEthernet0/0
O    192.168.45.0/24 [110/40] via 192.168.12.2, 00:12:56, FastEthernet0/0
O    192.168.24.0/24 [110/11121] via 192.168.12.2, 00:12:56, FastEthernet0/0
     10.0.0.0/24 is subnetted, 1 subnets
C       10.84.104.0 is directly connected, FastEthernet0/1
O    192.168.23.0/24 [110/20] via 192.168.12.2, 00:12:57, FastEthernet0/0
O    192.168.34.0/24 [110/30] via 192.168.12.2, 00:12:57, FastEthernet0/0
S*   0.0.0.0/0 [1/0] via 10.84.104.254
