EIGRP has been extended to be network-layer-protocol independent, thereby allowing DUAL to support other protocol suites. How Does EIGRP Work? EIGRP has four basic components: Neighbor Discovery/Recovery. Reliable Transport Protocol. DUAL Finite State Machine. Protocol Dependent Modules

2014年7月28日 · 要設定 EIGRP 的指令極其簡單，先用 router eigrp <AS no> 進入 EIGRP 設定，然後輸入要參與 EIGRP 的 network。 而 auto-summary 是預設的，在討論 Summary 的部份會再詳細說明。 另外需要注意的是，在同一個 AS 內的 EIGRP Router ，所有 AS Number 必需相同。 network 192.168.12.0. auto-summary. network 192.168.12.0. network 192.168.23.0. auto-summary. network 192.168.23.0. auto-summary. 預設情況下，Router 之間是利用 Multicast 溝 …

Enhanced Interior Gateway Routing Protocol (EIGRP) is an advanced distance-vector routing protocol that is used on a computer network for automating routing decisions and configuration. The protocol was designed by Cisco Systems as a proprietary protocol, available only on …

2020年11月20日 · EIGRP全称 [增强型内部网关路由选择协议] 是思科自主研发的动态路由选择协议，按类型划分是一款IGP协议，距离矢量协议，是一款基于传闻的协议。 EIGRP是思科的私有协议，直到13年，此协议才被公有化。 3. 算法 机制优良. EIGRP在交互路由之前，会交互一个hello包，用于建立邻居，当邻居建立起来后，hello包则会周期性的在邻居间发送，这个周期要么5S一次，要么60S一次。 如果在3倍的hello时间内都没有收到邻居发送的hello包，则会认为邻 …

2014年11月24日 · The Enhanced Interior Gateway Routing Protocol (EIGRP) is an enhanced version of the Interior Gateway Routing Protocol (IGRP) developed by Cisco. The convergence properties and the operating efficiency of EIGRP have improved substantially over IGRP, and IGRP is now obsolete.

2023年8月31日 · EIGRP is an enhanced distance vector protocol, which relies on the Diffused Update Algorithm (DUAL) to calculate the shortest path to a destination within a network. There are two major revisions of EIGRP, versions 0 and 1.

In this course you will learn: Why EIGRP is called an “advanced distance vector” or “hybrid” routing protocol. How to configure EIGRP on Cisco IOS routers. How to read the EIGRP topology table. How to configure EIGRP filtering with prefix-lists, distribute-lists and route-maps. Advanced features like the EIGRP stub types. And many other topics…

2020年2月16日 · EIGRP:Enhanced Interior Gateway Routing Protocol 即 增强内部网关路由协议。 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（2013年已经公有化）。 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.EIGRP采用DUAL来实现快速收敛。 运行EIGRP …

2022年6月16日 · Enhanced Interior Gateway Routing Protocol (EIGRP) is a dynamic routing protocol that is used to find the best path between any two-layer 3 devices to deliver the packet. EIGRP works on network layer Protocol of OSI model and uses protocol number 88.

EIGRP is Cisco proprietary which means it is available only on Cisco routers and switches. EIGRP employs an algorithm referred to as the Diffusing Update Algorithm (DUAL) which guarantees fast convergence and loop-free operation at all times.
