网络工程 - ASA 5505+Cisco 2811 路由器 - 吾爱随笔录

我为实验室购买了一些旧的网络设备，现在尝试通过连接到我的 Comcast 调制解调器来设置它。我有一个桥接模式的商务级调制解调器

0/0 - Global IP (Vlan2)
0/1 - 192.168.1.1 (Vlan10). DHCP is used on this device.
Static route 0.0.0.0 0.0.0.0 (Global IP Gateway).
Router EIGRP 90 (network 172.16.100.0 0.0.0.255)



Connected to port 0/1 of the 5505 is a Cisco 2811 Router
Port 0/0 is assigned 192.168.1.254.
Port 0/1 is assigned 172.16.100.1
Static Route of 0.0.0.0 0.0.0.0 192.168.1.1

Connected to port 0/1 of the 2811 is a Cisco 3550

请参阅下面的配置

我的问题是我可以从 3550 跟踪路由并且只能到达 172.16.100.1 如果我在 2811 上跟踪路由到外部，我可以到达任何我想要的地方。这似乎让我相信 2811 路由器存在问题。我错过了什么？DHCP 是 5505 上的问题吗？
