是否可以通过交换机删除/阻止EIGRP邻居连接？

Question

我有一个4路由器，通过一个多层交换机彼此连接。是否可以通过开关删除/阻止EIGRP邻居？

例如，我有这样一个拓扑：

我想把EIGRP的邻居从RA移到RB (10.10.0.2)，但是PC0和PC1在我通过交换机删除它之后仍然可以互相切换。有可能吗？谢谢。

Router0#sh ip eigrp ne
IP-EIGRP neighbors for process 10
H   Address         Interface      Hold Uptime    SRTT   RTO   Q   Seq
                                   (sec)          (ms)        Cnt  Num
0   10.10.3.2       Fa             13   00:14:48  40     1000  0   42
1   10.10.0.2       Fa0/0          11   00:11:53  40     1000  0   42

下面是核心交换机配置：

Answer 1

我要指出的第一件事是，当你只分享部分信息时，我们必须做出假设，它们可能是错误的。你给我们的信息越多，我们的答案就越好。

现在您已经提供了设备配置，我冒昧地创建了一个新的图表，向您展示一种更好地表示网络的方法。这是一个逻辑视图，使路由器之间的互连更加清晰。

现在我们可以看到真正的拓扑结构了，有许多方法可以实现您的目标。

选项1.您必须在所有路由器上配置静态邻居。eigrp neighbor命令使用单播hellos，而不是多播，因此必须指定邻居在所有路由器上的位置。例如：

router eigrp 1
network 10.0.0.0
network 192.168.0.0
neighbor 10.10.3.2 fa 0/0

选项2.在链接上配置被动接口：

router eigrp 1
passive-interface fa0/0.10

选项3.从路由域中删除接口。

router eigrp 10
network 10.10.3.0 0.0.0.3
network 192.168.1.0

请注意，EIGRP没有在界面fa0/0.10上运行。
