《路由器关于 eigrp实验与协议》

本文主要是介绍《路由器关于 eigrp实验与协议》，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

<pre class="html" name="code">EIGRP
EIGRP:Enhanced Interior Gateway Routing Protocol 即 增强内部网关路由线路协议。也翻译为 加强型内部网关路由协议。 EIGRP是Cisco公司的私有协议。Cisco公司是该协议的发明者和唯一具备该协议解释和修改权的厂商。 EIGRP结合了链路状态和距离矢量型路由选择协议的Cisco专用协议，采用弥散修正算法（DUAL）来实现快速收敛，可以不发送定期的路由更新信息以减少带宽的占用，支持Appletalk、IP、Novell和NetWare等多种网络层协议。
1.支持多种网络层协议
EIGRP使用协议无关模块来支持IPv4、IPv6、Apple Talk和IPX，以满足特定网络层需求。
2. 使用多播和单播
EIGRP在路由器之间通信时使用多播和单播而不是广播，因此终端站不受路由更新和查询的影响。EIGRP使用的多播地址是224.0.0.10
3. 支持变长子网掩码（VLSM)
EIGRP是一种无类路由协议，它将通告每个目标网络的子网掩码，支持不连续子网和VLSM
