CCNA培训课总结笔记--配置EIGRP实验(十)

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
IP-EIGRP Topology Table for AS(100)/ID(172.16.1.1)

Codes: P - Passive, A - Active, U - Update, Q - Query, R - Reply,
r - reply Status, s - sia Status

P 10.2.2.0/24, 1 successors, FD is 2681856
via 10.1.1.2 (2681856/2169856), Serial1/0
P 10.0.0.0/8, 1 successors, FD is 2169856
via Summary (2169856/0), Null0
P 10.1.1.0/24, 1 successors, FD is 2169856
via Connected, Serial1/0
P 192.168.1.0/24, 1 successors, FD is 2707456
via 10.1.1.2 (2707456/2195456), Serial1/0
P 172.16.0.0/16, 1 successors, FD is 281600
via Summary (281600/0), Null0
P 172.16.1.0/24, 1 successors, FD is 281600
via Connected, Ethernet0/0
R1#show ip route eigrp
172.16.0.0/16 is variably subnetted, 2 subnets, 2 masks
D 172.16.0.0/16 is a summary, 00:02:21, Null0
10.0.0.0/8 is variably subnetted, 3 subnets, 2 masks
D 10.2.2.0/24 [90/2681856] via 10.1.1.2, 00:01:43, Serial1/0
D 10.0.0.0/8 is a summary, 00:02:21, Null0
D 192.168.1.0/24 [90/2707456] via 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
10.0.0.0/8 for Ethernet0/0
Summarizing with metric 2169856
Maximum path: 4
Routing for Networks:
10.0.0.0
172.16.0.0
Routing Information Sources:
Gateway Distance Last Update
(this router) 90 00:02:34
10.1.1.2 90 00:01:43
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.
R1#show ip eigrp traffic

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
R2#show ip eigrp topology
IP-EIGRP Topology Table for AS(100)/ID(10.2.2.2)

Codes: P - Passive, A - Active, U - Update, Q - Query, R - Reply,
r - reply Status, s - sia Status

P 10.1.1.0/24, 1 successors, FD is 2169856
via Connected, Serial1/1
P 10.2.2.0/24, 1 successors, FD is 2169856
via Connected, Serial1/0
P 192.168.1.0/24, 1 successors, FD is 2195456
via 10.2.2.3 (2195456/281600), Serial1/0
P 172.16.0.0/16, 1 successors, FD is 2195456
via 10.1.1.1 (2195456/281600), Serial1/1
R2#show ip route eigrp
D 172.16.0.0/16 [90/2195456] via 10.1.1.1, 00:04:57, Serial1/1
D 192.168.1.0/24 [90/2195456] via 10.2.2.3, 00:04:39, Serial1/0
R2#show ip route
Codes: C - connected, S - static, R - RIP, M - mobile, B - BGP
D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
E1 - OSPF external type 1, E2 - OSPF external type 2
i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2
ia - IS-IS inter area, * - candidate default, U - per-user static route
o - ODR, P - periodic downloaded static route

Gateway of last resort is not set

D 172.16.0.0/16 [90/2195456] via 10.1.1.1, 00:05:04, Serial1/1
10.0.0.0/24 is subnetted, 2 subnets
C 10.2.2.0 is directly connected, Serial1/0
C 10.1.1.0 is directly connected, Serial1/1
D 192.168.1.0/24 [90/2195456] via 10.2.2.3, 00:04:46, Serial1/0
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R3上的
R3#show ip route
Codes: C - connected, S - static, R - RIP, M - mobile, B - BGP
D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area

ia - IS-IS inter area, * - candidate default, U - per-user static route
o - ODR, P - periodic downloaded static route

Gateway of last resort is not set

D 172.16.0.0/16 [90/2707456] via 10.2.2.2, 00:05:04, Serial1/1
10.0.0.0/8 is variably subnetted, 3 subnets, 2 masks

D 10.0.0.0/8 is a summary, 00:05:09, Null0
C 192.168.1.0/24 is directly connected, Ethernet0/0

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.
