网络工程 - VLAN 接口上的 EIGRP 保持时间过期 - 吾爱随笔录

我用 VLAN 和 EIGRP 路由配置了 2 个第 3 层交换机。

但它总是返回这样的消息：

%DUAL-5-NBRCHANGE: IP-EIGRP 2019: Neighbor 192.168.20.253 (Vlan20) is down: holding time expired

%DUAL-5-NBRCHANGE: IP-EIGRP 2019: Neighbor 192.168.10.253 (Vlan10) is down: holding time expired

我在 DSW-01（第 3 层交换机）上的运行配置：

这个问题有什么解决办法吗？
