实验目的:
熟悉掌握
EIGRP
的配置及相关命令
.
学会如何验证
EIGRP
的过程
.
实验拓扑图:
实验内容:
路由器的配置
先来看
R1
上的配置
Router>en
Router#conf t
Enter configuration commands, one per line. End with CNTL/Z.
粘贴上基本命令
Router(config)#enable password cisco
Router(config)#no ip domain-lookup
Router(config)#line con 0
Router(config-line)# exec-timeout 0 0
Router(config-line)# logging synchronous
Router(config-line)#
Router(config-line)#line aux 0
Router(config-line)# exec-timeout 0 0
Router(config-line)# logging synchronous
Router(config-line)#line vty 0 4
Router(config-line)#
Router(config-line)#
Router(config-line)# exec-timeout 0 0
Router(config-line)# password cisco
Router(config-line)#
Router(config-line)# login
Router(config-line)#
Router(config-line)#
Router(config-line)#alias exec a sh ip int bri
Router(config)#alias exec b sh ip route
Router(config)#alias exec c sh ip route rip
Router(config)#alias exec d sh run
Router(config)#
Router(config)#host R1
R1(config)#interface e0/0
R1(config-if)#ip address 172.16.1.1 255.255.255.0
R1(config-if)#no shutdown
接下来配置名称
,
各接口地址
R1(config-if)#exit
R1(config)#interface s1/0
R1(config-if)#ip address
10.1.1
.1 255.255.255.0
R1(config-if)#clock rate 64000
R1(config-if)#no shutdown
同理
R2
上的配置
,
粘贴命令部分省略
Router(config)#host R2
R2(config)#interface s1/1
R2(config-if)#ip address
10.1.1
.2 255.255.255.0
R2(config-if)#no shutdown
R2(config-if)#exit
R2(config)#interface s1/0
R2(config-if)#ip address
10.2.2
.2 255.255.255.0
R2(config-if)#clock rate 64000
R2(config-if)#no shutdown
R3
上的配置
Router(config)#host R3
R3(config)#interface s1/1
R3(config-if)#ip address
10.2.2
.3 255.255.255.0
R3(config-if)#no shutdown
R3(config-if)#exit
R3(config)#interface e0/0
R3(config-if)#ip address 192.168.1.1 255.255.255.0
R3(config-if)#no shutdown
好了
,
现在开始配置
EIGRP
先从
R1
上开始
R1(config)#router eigrp 100
R1(config-router)#network 172.16.0.0
R1(config-router)#network
10.0.0
.0
R1(config-router)#exit
R2
上的配置
R2(config)#router eigrp 100
R2(config-router)#network
10.0.0
.0
R3
上的配置
R3(config)#router eigrp 100
R3(config-router)#network 192.168.1.0
R3(config-router)#network
10.0.0
.0
最后让我们来验证一下
EIGRP
的配置是否生效
看下
R1
的上
R1#show ip eigrp neighbors
IP-EIGRP neighbors for process 100
H Address Interface Hold Uptime SRTT RTO Q Seq
(sec) (ms) Cnt Num
0
10.1.1
.2 Se1/0 12 00:01:11 81 486 0 5
这命令是查看
EIGRP
的邻居的
R1#show ip eigrp topology

R1#show ip route eigrp

D

D 192.168.1.0/24 [90/2707456] vi
a 10.1.1
.2, 00:01:23, Serial1/0
该命令查看
EIGRP
的拓扑路由表的
,
上面可以看出
R1
已经学习到了
R2,R3
上的
EIGRP
信息
R1#show ip protocols
Routing Protocol is "eigrp 100"
Outgoing update filter list for all interfaces is not set
Incoming update filter list for all interfaces is not set
Default networks flagged in outgoing updates
Default networks accepted from incoming updates
EIGRP metric weight K1=1,
K2
=0, K3=1, K4=0, K5=0
EIGRP maximum hopcount 100
EIGRP maximum metric variance 1
Redistributing: eigrp 100
EIGRP NSF-aware route hold timer is 240s
Automatic network summarization is in effect
Automatic address summarization:
172.16.0.0/16 for Serial1/0
Summarizing with metric 281600
Summarizing with metric 2169856
Maximum path: 4
Routing for Networks:
172.16.0.0
Routing Information Sources:
Gateway Distance Last Update

Distance: internal 90 external 170
这命令即详细地显示了运行的
EIGRP
协议的信息
,
还有运行着的路由状态信息
.

最后这条命令即是查看有关
EIGRP
协议的数据包发送和接收的数量
.
看完
R1
的
,
再看一下
R2
的

可以看到
,
其实也差不多的
.
根据拓扑图来看就会明白
.
最后看下

其实配置
EIGRP
很简单的
,
注意一下它的衡量是根据带宽和时延来计算的
.
至于计算的过程比较复杂
