在3650交换机上将多个VLAN集群到单个中继端口

Question

早上：

我是思科包追踪器世界的新手，我正在为一个uni项目创建一个网络。到目前为止，我得到的是：

5个VLAN(细分为192.168.2.0/26、192.168.3.0/36等)

它们都连接到3650交换机上的端口Gig 1/0/2 - 1/0/6。

终端设备能够相应地与所有各自的VLANs通信。

VLAN都在交换机上终止，(我相信)中继到端口1/0/24，端口IP为192.168.40.1/30。端口1/0/24然后用IP 192.168.40.2连接到端口9/0上的通用PT路由器上的端口，这也是默认的IP路由器(最后一个度假村的网关)。

从那里，路由器连接到另一个路由器，这两个路由器都位于192.168.50.0/30的子网中，然后该路由器连接到子网192.168.60.0/30上的另一个3650交换机。

路由器和交换机可以在没有问题的情况下互相切换。我使用EIGRP建立了路由。

我似乎遇到的问题是，无论我尝试什么，我都不能让终端设备的数据包比集群端口更远。例ping的结果如下：

敲击开关：

C:>ping 192.168.40.1用32个字节的数据ping192.168.40.1：

192.168.40.1: bytes=32 time=11ms TTL=255回复192.168.40.1: bytes=32 time=35ms TTL=255回复192.168.40.1: bytes=32 time=30ms TTL=255回复192.168.40.1: bytes=32 time=36ms TTL=255

敲击路由器

C:>ping 192.168.40.2

用32个字节的数据ping192.168.40.2：

请求超时。请求超时。请求超时。请求超时。

我觉得我已经快破解了，但是从1/0/23到9/0之间的链接还在下降，我不知道如何把它拿出来测试。

Answer 1

您在(第3层)交换机上没有启用EIGRP，因此路由器和其他设备不知道如何到达交换机上的网络。

和BTW，你不是在中继VLAN。VLAN在交换机上终止。端口1/0/24是一个路由接口，而不是主干端口。
