博主本人又来填坑了，协议配置有俩种方法，一种是Quagga（不再更新）,另一个叫FRR。
Quagga很多年了，不说了，介绍一下FRR，
FRRouting（Free Range Routing）是一种开源的路由软件套件，它具有广泛的网络路由功能和灵活的可定制性。其主要功能是为计算机网络提供动态路由功能，使数据包能够在网络中选择最佳路径进行转发。FRRouting 可以应用于各种网络环境和场景，以下是 FRRouting 的一些常见应用场景：
- 企业网络: 提供动态路由协议（如 OSPF、BGP）来管理和优化网络流量。
2.数据中心网络: 在数据中心网络中，FRRouting 可以用于实现跨子网的灵活路由和负载均衡，支持各种网络拓扑结构和流量分布策略，以提供高性能和可扩展性。
3.广域网（WAN）互联: FRRouting 支持常用的广域网路由协议，例如 BGP（边界网关协议），允许不同地理位置的网络以可靠而高效的方式连接在一起。
问题：不支持mininet，支持py cmd控制

我们这个项目用的是Quagga

我们通过这个代码修改成自己的拓扑

发现时延设置问题（解决）需要加上TClink：
