CCNP路由实验---1、EIGRP的基本配置一、实验目的1、掌握EIGRP的基本配置。
2、掌握EIGRP的通配符掩配置方法。
3、掌握EIGRP的自动汇总特性，以及如何关闭自动汇总。
4、掌握EIGRP的手工汇总。
二、实验拓扑实验步骤：1、配置各路由器的名称、相连接口IP地址；R1(config)#int s1/1R1(config-if)#ip add 172.16.1.1 255.255.255.252R1(config-if)#no shutR1(config)#int loopback 0R1(config-if)#ip add 10.1.0.1 255.255.255.0R1(config-if)#int loopback 1R1(config-if)#ip add 10.1.1.1 255.255.255.0R1(config-if)#int loopback 2R1(config-if)#ip add 10.1.2.1 255.255.255.0R1(config-if)#int loopback 3R1(config-if)#ip add 10.1.3.1 255.255.255.0其它R2、R3类似进行配置。
配置完后用ping命令确认各路由器的直连口的互通性。
2、配置EIGRP协议，设置自治系统号为80R1：R1(config)#router eigrp 80R1(config-router)#network 172.16.0.0R2：R2(config)#router eigrp 80R2(config-router)#network 172.16.0.0R2(config-router)#network 111.111.0.0R3：R3(config)#router eigrp 80R3(config-router)#network 172.16.0.0备注：通常在路由器上配置EIGRP宣告通路网络时使用两种方法，方法1：network +主类网络号，这样可以将路由器上相关地址的接口直接加入到EIGRP 路由进程中去；方法2：使用通配符掩码进行配置，例如network X.X.X.X 0.0.0.X。
环境：三台路由器通过串行接口相连。
要求：配置R2为帧中继交换机，使R1和R3运行在帧中继网络上；在R1和R3分别启用loop0口，并且运行EIGRP路由选择协议。

路由协议分类路由协议可分为有类路由协议和无类路由协议：有类路由协议：即路由器发送路由更新时不带掩码，RIPv1，IGRP无类路由协议：即路由器发送路由更新时带子网掩码，RIPv2，EIGRP，OSPF路由协议可分为距离矢量型和链路状态型：链路状态型：OSPF1.更新时以组播或单播形式发送2.发送路由更新包给邻居时不发送整张路由表，只发送链路状态（接口和IP段）3.链路状态有3张表，按顺序建立以下3个表:邻居表-->拓扑表-->路由表4.增量更新（触发更新）5.有区域划分距离矢量：RIP，IGRP，EIGRP（增强IGRP）1.更新时以广播形式发送2.EIGRP被称为高级距离矢量路由协议，因为它不具有区域划分的概念路由协议可分为外部路由协议和内部路由协议：外部路由协议：BGP内部路由协议：RIP,EIGRP,OSPFEIGRP（一）EIGRP具有以下特征：1.是一个高级距离矢量路由协议2.快速收敛（三张表，EIGRP自身算法DUAL）3.部分更新（或触发更新）4.支持VLSM(可变长子网掩码)，不连续子网5.支持多种网络层协议（IP,IPX,APPLE TALK）6.支持复杂网络拓扑7.以组播或单播进行更新，组播地址是224.0.0.108.支持手工汇总，默认情况下路由表将学到的路由自动汇总到主类网络（A B C等）9.百分百无环路10.支持等价和非等价负载均衡（二）EIGRP关键技术1.使用hello包进行邻居的发现与保持，hello包的目标地址是224.0.0.102.使用RTP协议：用来保证EIGRP数据可靠并且有序传输3.DUAL算法：用来计算最优路由的算法4.PDMS：用来支持不同网络层协议（三）EIGRP关键术语（DUAL算法中）1.AD（advertise distance）：下一跳路由器到目标网络的cost值2.FD（Feasible distance）：指本路由器到目标网络的cost值3.successor（主路由器）：指到目标网络的下一跳路由器4.feasible successor（备份路由器）：指到目标网路备份路由器（必须满足FC条件才存在，否则只有主路由）5.FC（feasible condition可行性条件）：条件是feasible successor的AD必须小于successor 的FD，该技术用来避免环路（四）EIGRP的五种包：1.hello包，用于保持与建立邻居关系的包，包的目标地址224.0.0.10，默认情况下EIGRP 是每隔5s发送一次hello包，在帧中继网络路上，每60s发送一次hello包2.UPDATE更新包，包的目标地址也是224.0.0.10或者指定的单播地址3.QUERY查询包，包的目标地址可以是224.0.0.10或者指定的单播地址4.Reply答复包，包的目标地址是单播地址5.ACK，确认包，包的目标地址是单播地址，UPDATE包，QUERY包，REPLY包，这三种包需要对方回复ACK包* hold time 为hello包发送时间的3倍，即15s，因此正常状态下hold time在10~14s 之间（五）EIGRP的metric值（eigrp用32bit表示metric，igrp只有24bit，eigrp和igrp共存时，只需要igrp metric乘以256即可换算成eigrp的metric值）*在EIGRP中，metric=cost=FDmetric=bandwidth（slowest link最小的）+delay（sum of delays延迟之和）metric=（10000000/链路上最小带宽+（sum）delay/10）*256计算过程中10^7/带宽应把小数位去掉，带宽单位为Kbit，时延单位为usEIGRP计算metric会用到的几个值:1.bandwith（带宽）k1=12.可靠性k2=03.delay（延迟）k3=14.接口负载k4=05.MTU k5=0（六）关于EIGRP的汇总知识点1.EIGRP默认是打开自动汇总的，只是在主类边界进行汇总，自动汇总后会产生一条汇总路由指向NULL0空接口（是为了避免路由环路）2.自动汇总只会对自己的直连网络进行汇总，不会对拓扑表里的条目进行汇总，而手工汇总可以对拓扑表里的条目进行汇总。
ITAA LEVEL 2：(路由部分)1：EIGRP的邻居发现和恢复机制。
只支持 MD5 加密方式.:邻居的形成必须是在同一个线路上不能是跨过一台路由器，并且两端都得起EIGRP协议，且协议的内容必须得一直才能建立起邻居。
邻居表里有接口和对应哪个路由器两个内容。
拓扑表里含有所有满足可行条件的路由条目包括AD和FD。
把最优路径放入路由表里了。
2：可靠传输协议（RTP）。
一、RTP-EIGRP的可靠传输协议RTP 负责 EIGRP packet 的按顺序(可靠)的发送和接收,这个可靠的保障是通过Cisco 私有的一个算法,reliable multicast 实现的,使用组播地址 224.0.0.10,每个邻居接收到这个可靠的组播包的时候就会以一个 unicast 作为确认按顺序的发送是通过 packet 里的 2 个序列号实现的,每个packet 都包含发送方分配的 1 个序列号,发送方每发送 1 个packet,这个序列号就递增 1.另外,发送方也会把最近从目标路由器接收到的 packet的序列号放在这个要发送的 packet 里，在某些情况下,RTP 也可以使用无需确认的不可靠的发送,并且使用这种不可靠发送的 packet 中不包含序列号 .二、如果 packet 通过可靠的组播方式发送出去,并且没有收到邻居反馈的 ACK 包,那么这个 packet 会再次以 unicast 的方式发送给那个未响应的邻居,虽然经过 16 次的重传 unicast,仍然没有收到 ACK 包的话,那么这个邻居就宣告为无效。
在从组播切换到 unicast 之前,等待 ACK 包的时间可以由multicast flow timer(MFT)指定,后续的重新传 unicast 的发送间隔可以由 RTO(retransmission timeout)指定.每个邻居的MFT 和 RTO 都可以通过SRTT(smooth round-trip time)来计算,SRTT 的单位是(毫秒)ms,用来衡量路由器从发送 EIGRP packet 到某个邻居并接收到这个邻居的 ACK 包所花费的平均时间。

CCNP 实验一、帧中继实验：上面为逻辑图以上为物理图，逻辑图中的FR FR2 实际上可以是一个设备，所有的设备s1/2口都连接在帧中继交换机上，当不同的接口连接到不同的网段，就形成了逻辑图的部署样式。
no arp frame 和no frame-relay inverse-arp 的区别在帧中继上，ARP指应答一个IP映射的请求，而Inverse-ARP指发送一个IP映射的请求。
犹如Echo & Echo-reply，一个是被动的，一个是主动的。
你如果把ARP关闭了，那么当有需要请求IP映射时，路由器仍然会发出一个请求，但当他得到一个请求时，则不会应答。
反之，你若把inverse-ARP关闭，则没法发送映射请求，需要a、建立静态MAP b、建立点到点子接口或frame-relay interface DCCI。
如果2者都关闭，则相当于即不发送请求，也不会有应答R1 R2 R3 处于10.1.1.0/24网段，使用帧中继线路连接，建立全互连模型（full-mash结构）R1 R4处于14.1.1.0/24网段，使用帧中继线路连接R2 R3 R5 位于50.1.1.0/24网段，使用帧中继线路连接全网使用EIGRP基本配置：根据题目的要求，R1 连接R2和R3，全互连，则需要在R1 R2 R3配置多点子接口R1 连接R4是唯一一条线路，可以使用点到点子接口，也可以使用多点子接口R2 R3 同时连接R1 R5，可以采用多点子接口的方法。
在帧中继中，使用RIP 或者EIGRP时物理接口的水平分割默认关闭，是不生效的而多点子接口的水平分割默认开启，是生效的，而点到点子接口是不受水平分割影响的。

CCNP自学笔记----EIGRP在当前各未来的路由选择环境中，增强内部网关路由选择协议（EIGRP）提供了诸如路由选择信息协议第1版（RIPV1）和内部网关路由选择协议（IGRP）等传统的距离矢量路由选择协议所没有的优点和特性。
这些优点包括会聚速度快，占用的带宽少以及支持多种被路由的协议。
EIGRP是一种CISCO专有协议，同时具备链路状态和距离矢量路由选择协议的优点：1.快速会聚：EIGRP采用扩散更新算法（DUAL）来实现快速会聚。
2.占用的带宽更少：EIGRP不发送定期更新，而是在前往目的地的路径或度量值发生变化时使用部分更新。
3.支持多种网络层协议：EIGRP使用协议无关模块（PDM）来支持IP，APPLETALK和IPX，以满足特定的网络层需求。
4.在不同数据链路层协议和拓扑之间提供无缝连接性：使用EIGRP时，无需针对第2层协议做特殊的配置；而其他路由选择协议（如OSPF）对于不同的第2层协议（如以太网和帧中继）需要采用不同的配置。
传输EIGRP信息的IP分组使用其IP报头中使用协议号88。
与传统的路由选择协议相比，EIGRP最重要的优点之一是占用的带宽。
使用EIGRP时，运行数据流是以多播或单播而不是广播方式传输的，因此终端不受路由选择更新和查询的影响。
与其他协议相比，EIGRP和（IGRP）的一个重要优点是，支持在度量值不等的路径之间均衡负载，让管理员能够在网络中更好地分配流量。
EIGRP使用多播地址224.0.0.10。
EIGRP路由器从属于同一个自主系统的路由器那里收到HELLO分组后，将与该路由器建立邻接关系。
如果在保持时间过后仍未收到分组，将删除相应邻接关系以及从该邻居那里获悉的所有拓扑表条目，就像该邻居发送了一条指出所有这些路由都不可达的更新一样。
如果该邻居是前往某个目标网络的后继站，将从路由选择表中删除该网络，并计算替代路径。
即使HELLO间隔和保持时间不匹配，两台路由器也能成为EIGRP邻居；这意味着可以在路由器上独立地设置HELLO间隔和保持时间。
