思科CCNP培训笔记EIGRP综合实验-WOLFLAB实验室

八卦谈佚名 ▪ 2024-04-28 02:20:45

感谢关注WOLFLAB网络实验室，我们会陆续更新关于CCNP相关技术！

一、地址描述

1. R1-R5都有一个loopback0 IP ADD = 10.10.X.X/24，X=ROUTER NUMBER，比如R1 的LO0 =10.10.1.1/24。

2. R1-R3以太口地址为：1.1.123.X/27，X=ROUTER NUMBER。

3. R3-R4接口地址为：1.1.34.X/29，X=ROUTER NUMBER。

4. R2-R4接口地址为：1.1.24.X/29，X=ROUTER NUMBER。

5. R4-R5接口地址为：1.1.45.X/24，X=ROUTER NUMBER。

二、 BRIDGE

1. 如图所示, 配置R1-R3的以太口地址。

2. 如图所示, 配置R2-R4之间物理接口的IP ADDRESS，R3-R4之间物理接口的IP ADDRESS。

3. 如果所示，配置R4-R5之间的链路为PPP的封装，并配置相应的接口地址。

4. 配置R1-R5的loopback0。

5. 配置完成后，测试各直连链路应能正常通讯。

三、 RIP基本配置

1 .R1 R2 R3运行RIP Version 2，并把loopback0接口和直连以太网段宣告进RIP中。

R1(config)#router rip

R1(config-router)#ver

R1(config-router)#version 2

R1(config-router)#net

R1(config-router)#network 1.0.0.0

R1(config-router)#net

R1(config-router)#network 10.0.0.0

R1(config-router)#exit

R2(config)#router rip

R2(config-router)#ver

R2(config-router)#version 2

R2(config-router)#net

R2(config-router)#network 1.0.0.0

R2(config-router)#net

R2(config-router)#network 10.0.0.0

R2(config-router)#exit

R2(config)#router rip

R2(config-router)#no au

R2(config-router)#no auto-summary

R3(config)#router rip

R3(config-router)#ver

R3(config-router)#version 2

R3(config-router)#net

R3(config-router)#network 1.0.0.0

R3(config-router)#nei

R3(config-router)#net

R3(config-router)#network 10.0.0.0

R3(config-router)#exit

R3(config)#router rip

R3(config-router)#no au

R3(config-router)#no auto-summary

2.在三台路由器的路由表中都可以互相看到对方的loopback0路由。

3.在R1上，用最小的命令行，增加八个interface地址，地址为: 100.1.1.1/24 - 100.1.8.1/24，这八个地址在R1的RIP数据库中是作为外部路由出现。

R1(config)#int loo

R1(config)#int loopback 0

R1(config-if)#ip add

R1(config-if)#ip address 100.1.1.1.1 255.255.255.0 sec

R1(config-if)#ip address 100.1.1.1.1 255.255.255.0 secon

R1(config-if)#ip address 100.1.1.1 255.255.255.0 secon

R1(config-if)#ip address 100.1.1.1 255.255.255.0 secondary

R1(config-if)#ip add

R1(config-if)#ip address 100.1.2.1 255.255.255.0 sec

R1(config-if)#ip address 100.1.2.1 255.255.255.0 secondary

R1(config-if)#ip add

R1(config-if)#ip address 100.1.3.1 255.255.255.0 sec

R1(config-if)#ip address 100.1.3.1 255.255.255.0 secondary

R1(config-if)#

R1(config-if)#ip add

R1(config-if)#ip address 100.1.4.1 255.255.255.0 sec

R1(config-if)#ip address 100.1.4.1 255.255.255.0 secondary

R1(config-if)#ip add

R1(config-if)#ip address 100.1.5.1 255.255.255.0 sec

R1(config-if)#ip address 100.1.5.1 255.255.255.0 secondary

R1(config-if)#ip add

R1(config-if)#ip address 100.1.6.1 255.255.255.0 sec

R1(config-if)#ip address 100.1.6.1 255.255.255.0 secondary

R1(config-if)#ip add

R1(config-if)#ip address 100.1.7.1 255.255.255.0 sec

R1(config-if)#ip address 100.1.7.1 255.255.255.0 secondary

R1(config-if)#ip add

R1(config-if)#ip address 100.1.8.1 255.255.255.0 sec

R1(config-if)#ip address 100.1.8.1 255.255.255.0 secondary

R1(config-if)#

4.只在R1做配置，并使用最小的命令行，使R3上可以看到的这八个网段的七个, 看不到100.1.8.0/24这条路由，

且奇数路由的metric为5, 偶数路由的metric为7，不允许用Offset-list。

R1(config)#acc

R1(config-route-map)#set me

R1(config-route-map)#set metric 5

R1(config-route-map)#exit

R1(config)#router rip

R1(config-router)#redis

R1(config-router)#redistribute con

R1(config-router)#redistribute connected rou

R1(config-router)#redistribute connected route-map

R1(config-router)#redistribute connected route-map A

R1(config-router)#

6. 不可以在R2做任何配置，使R2看不到100网段的7条路由, 但可以看到R1和R3的loopback路由，不能通过Version 1, 2来解决此问题。

R1(config)#

R1(config)#router rip

R1(config-router)#passi

R1(config-router)#route rip

R1(config-router)#pass

R1(config-router)#passive-interface f0/0

R1(config-router)#nei

R1(config-router)#neighbor 1.1.123.3

R1(config-router)#network 10.10.3.3

R1(config-router)#

R3(config)#access-list 1 deny 100.1.0.0 0.0.7.0

R3(config)#acc

R3(config)#access-list 1 per

R3(config)#access-list 1 permit any

R3(config)# route rip

% Ambiguous command: " route rip"

R3(config)# router rip

R3(config-router)#dis

R3(config-router)#distri

R3(config-router)#distribute-list 1 out f0/0

四、 EIGRP 100配置

1. 在R2 R3 R4的链路运行EIGRP 100，将R4的loopback0接口宣告到EIGRP 100。在R4上，show ip eigrp neighbors，可以看到两个邻接关系。

R3(config)#router eigrp 100

R3(config-router)#net

R3(config-router)#network 1.1.34.3 0.0.0.0

R3(config-router)#

R2(config)#router eigrp

R2(config)#router eigrp 100

R2(config-router)#net

R2(config-router)#network 1.1.24.2 0.0.0.0

R4(config)#router eigrp 100

R4(config-router)#network 1.1.24.4 0.0.0.0

2. 假设R4的F0/0口的地址为:150.1.1.1/24，使R4与BB2建立EIGRP邻接关系，此时R4会收到很多从BB2传递过来的路由，包括：A、B、C类。用最小的Prefix-list命令，只允许B类路由进入R4。

R4(config)#int f0/0

R4(config-if)#ip add

R4(config-if)#ip address 150.1.1.1 255.255.255.0

R4(config-if)#ip pr

R4(config-if)#ip pre

R4(config-if)#exit

R4(config)#ip pre

R4(config)#ip prefix-list B seq

R4(config)#ip prefix-list B seq 5 pert

R4(config)#ip prefix-list B seq 5 per

R4(config)#ip prefix-list B seq 5 permit 128.0.0.0/2 le 32

R4(config)#router ei

R4(config)#router eigrp 100

R4(config-router)#net

R4(config-router)#network 150.1.1.1 0.0.0.0

R4(config)#router ei

R4(config)#router eigrp 100

R4(config-router)#dis

R4(config-router)#distr

R4(config-router)#distribute-list pre

R4(config-router)#distribute-list prefix

R4(config-router)#distribute-list prefix B in f0/0

R4(config-router)#

3. 在R2和R3上做RIP与EIGRP的双向重分布。使R4上看不到100.0.0.0网段的任何路由。此解决方案不能用Route-map，不能用基于接口的过滤，也不能通过metric的方法。

R2(config)#router ei

R2(config)#router eigrp 100

R2(config-router)#redis

R2(config-router)#redistribute rip me

R2(config-router)#redistribute rip metric 100000 10 255 1 1500

R2(config-router)#exit

R2(config)#router rip

R2(config-router)#red

R2(config-router)#redistribute eig

R2(config-router)#redistribute eigrp 100 me

R2(config-router)#redistribute eigrp 100 metric 1

R2(config-router)#

R3(config)#router ei

R3(config)#router eigrp 100

R3(config-router)#redi

R3(config-router)#redistribute

R3(config-router)#redistribute rip me

R3(config-router)#redistribute rip metric 1

*Nov 3 22:36:58.167: %DUAL-5-NBRCHANGE: IP-EIGRP(0) 100: Neighbor 1.1.34.4 (Serial1/0) is up: new adjacency

R3(config-router)#redistribute rip metric 100000 10 255 1 1500

R3(config-router)#

R3(config-router)#exit

R3(config)#router rip

R3(config-router)#

R3(config-router)#re

R3(config-router)#redistribute ei

R3(config-router)#redistribute eigrp 100 me

6. 在R2上，增加一个loopback1，其IP地址为：161.1.1.1/24，宣告进入EIGRP，这时R4上应只可以看到161网段的三条路由: 161.1.0.0/16，161.1.0.0/18，161.1.0.0/20三条路由。而在R1上只能看到161.1.1.0/24的路由，不能用Route-map，可以使用基于接口的过滤。

2. 在R5上增加一个loopback1，其地址为：7.7.7.7/32，使其在R4看到是一条外部路由: 7.7.7.7/32 ( 90/xxxxx )。 R4要向R5只注入一条默认路由，不能用接口下汇总，也不能用distribute-list，不能用route-map。

3. 在R4上，把EIGRP 100与EIGRP 99做双向重分布。在R1上看到7.7.7.7/32这条路由下一跳指向R2，如果R2不可达，则R1可以通过R3到达到达此路由。R2与R3是可以相互传递路由，此方案还需要考虑双点双向重分布可能会出现的路由环路或次优路径的问题。
