GNS3 无法从以太网接口 ping 到串行接口

网络工程思科路由器以太网 IPv6 gns3

2022-02-10 17:07:46

因此，我正在为我的一门课程做一个实验室，该课程涉及 ipv6 和使用 EIGRP 进行路由。当我设置网络并为路由器接口分配 IPV6 地址时，我在 ping 整个网络时遇到问题。在网络的串行部分，我可以 ping 任何分配了 IP 并使用串行连接的端口，反之亦然，网络的另一半使用以太网进行连接。不幸的是，如果从使用相反接口连接的路由器 ping，我无法 ping 使用以太网或串行的接口。

串行接口似乎存在的一个大问题是您没有将 DTE 连接到 DCE。您必须在串行连接的一侧设置时钟速率以将接口设置为 DCE，否则您尝试将 DTE 连接到 DTE，这不起作用。您需要将 DTE 连接到 DCE。

例如，R2：

interface Serial2/0
 no ip address
 ipv6 address 2001:FACE:1111:F001::1/64
 serial restart-delay 0
!

连接到 R5：

interface Serial2/0
 no ip address
 ipv6 address 2001:FACE:1111:F001::2/64
 serial restart-delay 0
!

但是您没有在任一侧设置时钟速率，您必须这样做才能将一侧设置为 DCE。

你可以做类似 R5 的事情：

interface Serial2/0
 clock rate 64000

您需要通过所有串行链路并通过设置时钟速率将一侧设置为 DCE。

使用 EIGRP 进行路由。

我在您的任何配置中都找不到任何 EIGRP 配置。您将需要设置一个路由协议，例如 EIGRP，或者您需要配置静态路由，以便所有网络都能到达所有其他网络。必须告诉路由器如何到达网络，路由器学习如何到达其他网络的方式有以下三种：

路由器天生就知道直接连接的网络。
路由器可以配置静态路由
路由器可以通过路由协议动态学习路由
