Cisco 1811w 路由问题

  • 772

我有一台 Cisco 1811w，我现在只是尝试进行基本配置。我在 fa0 上使用有线互联网 (TWC)（现在只是常规的内部 dhcp，还没有完成桥接）和 fa1 作为内部 10.0.0.0/24

连接到 fa1 的 PC 确实获得了 dhcp 和路由器设置，但无论是在 PC 上还是在路由器中，都无法 ping 通。不知道我做错了什么。

路由器内部的 ping 测试：

Router#ping 8.8.8.8
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 8.8.8.8, timeout is 2 seconds:
.....
Success rate is 0 percent (0/5)

知识产权信息：

FastEthernet0              192.168.0.5     YES DHCP   up                    up      
FastEthernet1              10.0.0.1        YES NVRAM  up                    down (nothing plugged into 1 at the moment)

    @MarkoPolo 是对的。默认网关有问题。但我认为您应该使用默认网关，思科可以通过 DHCP 从您的 ISP 获得该网关：

    ip route 0.0.0.0 0.0.0.0 dhcp

  2. 如果它会帮助其他人，我的配置是：

    version 12.4 service timestamps debug datetime msec service timestamps log datetime msec no service password-encryption ! hostname Router ! boot-start-marker boot-end-marker ! enable secret 5 $1$XweJ$NMtNuu/R4emfBU0rpjamg1 ! no aaa new-model ! ! dot11 syslog ! ! ip cef no ip dhcp use vrf connected ip dhcp excluded-address 10.0.0.1 10.0.0.10 !
