无法对流量进行深层次路由(3层设计)

Question

因此，为了测试此配置的简单性，我有一个示例项目，如下所示：

细目：

配置

配置在多层交换机上的vlans也是vtp服务器：

vlan 2：

ip地址192.168.2.1 255.255.255.0

ip助手-地址192.168.3.1

vlan 3：

• ip地址192.168.3.2 255.255.255.0

dhcp驻留在vlan 3中，静态地址192.168.3.1

游泳池：

• 默认网关: 192.168.3.254
• 启动ip: 192.168.3.2
• 子网掩码: 255.255.255.0
• 最高用户数: 200

所有交叉连接都是主干(已验证)

所有直接连接都分配给vlan 3(已验证)

pc 1和2可以正确地从DHCP服务器接收响应，但PC0不能。

在尝试调试我正在为我的网络101类工作的三层网络设计时，我试图让它工作起来。经过几天的努力，试图找出为什么流量没有正确的路由，我打破了设计，试图找出故障点。就我的范围而言，问题来自中间交换机(交换机1)，它是分发层的一部分，但我无法理解它的配置有什么问题(所有端口主干、vtp模式透明)。

我觉得我在路由设置中错过了一些非常基本的东西，特别是在过去我已经让这个配置工作了，但是我无法复制正确的配置。

Answer 1

您要么需要使用VTP，要么在全局配置中手动配置VLAN，并且可以选择命名它们以使其有意义：

Vlan 2
 name Name2
!
Vlan3
 name Name3
