做的单笔路由器试验，可客户机怎么也ping不通网关和其他vlan的客户端
麻烦大家给参谋参谋

switch划分两个新vlan10:int fa0/1 ---pc1                          vlan20:int fa0/2 ---pc2         trunk:int fa0/12   dot1q
router 分了两个子接口：

interface Ethernet0.10
encapsulation dot1q 10
ip address 192.168.10.254 255.255.255.0

interface Ethernet0.20
encapsulation dot1q 20
ip address 192.168.20.254 255.255.255.0   

pc1---switch fa0/1
     Ethernet adapter Local Area Connection:
        IP Address. . . . . . . . . . . . : 192.168.10.1
        Subnet Mask . . . . . . . . . . . : 255.255.255.0
        Default Gateway . . . . . . . . . : 192.168.10.254
pc2---switch fa0/2
        IP Address. . . . . . . . . . . . : 192.168.20.1
        Subnet Mask . . . . . . . . . . . : 255.255.255.0
        Default Gateway . . . . . . . . . : 192.168.20.254

Ther configuration is correct. check if there is any phasical failure.

The router will be connected to a switch via a FastEthernet port (or higher).

The router port cannot be a regular Ethernet port, since the router port will need the ability to send and receive data at the same time.

try the lab again with a router which has fastethernet ports.

之前我用的是2600的路由器，只有普通的以太口。做了多次后，一咬牙，换了个4500的路由器，成功了。上次做VTP试验的时候，用pack模拟器的时候总是不成功，后来换做boson，成功了。今天应该是物理端口速率影响的。可，2600却可以配置子接口。能配置却又不行。模拟器还真的只是模拟的！

问题蛮多的~~254应该是广播地址吧~貌似不可做VLAN的默认网关。
看你的 sw   trunk 链路的封装写了没？
sw的默认网关也没起~~

恩我来翻译一下大邹的..
他的意思是叫你换个有FASTETHERNAT接口的路由器
原因是The router port cannot be a regular Ethernet port?
  路由端口不能做为正常的以太网口?
不懂拉...反正我理解是交换机是FastEhernet口,的,比路由器的口快
所以通不了,
可以通过设置来调节速度么???我记得好象没学过:)

matthew

不能在E0口上做TRUNK....只能在F口或者以上的口上做TRUNK

单臂路由要求最低为100Mbps

保命要紧
