EIGRP综合实验
本实验可能会有一两个出错的地方，希望大家进行实验测试后，可以指正！当然绝大部分都是正确滴！
实验A：基本配置
A.0)实验目的：
熟悉eigrp的基本配置
A.1)实验拓扑：
A.2)实验步骤
步骤一：基本ip地址配置
R1：
R1#conf t
R1(config)#int e0/0
R1(config-if)#ip add 12.12.12.1 255.255.255.0
R1(config-if)#no shut //路由器接口默认关闭
R1(config-if)#int lo0
R1(config-if)#ip
R1(config-if)#ip add 10.1.1.1 255.255.255.0
R1(config-if)#no shut //不需要
R1(config-if)#end
R2：
R2#CONF T
R2(config)#int e0/0
R2(config-if)#ip add 12.12.12.2 255.255.255.0
R2(config-if)#no shut
R2(config-if)#int e0/1
R2(config-if)#ip add 23.23.23.2 255.255.255.0
R2(config-if)#no shut
R2(config-if)#int lo0
R2(config-if)#ip add 20.2.2.2 255.255.255.0

R3(config-if)#ip add 30.3.3.3 255.255.255.0
R3(config-if)#no shut
R3(config-if)#end
步骤二：加入eigrp路由协议
R1::
R1#conf t
R1(config)#router eigrp 123
R1(config-router)#eigrp router-id 1.1.1.1
R1(config-router)#no auto-summary //某网络信息经过自动汇总路由器A到达路由器B，B的路由表显示该网络的汇总信息。
R1(config-router)#net 10.1.1.0 0.0.0.255
R1(config-router)#net 12.12.12.0 0.0.0.255
R1(config-router)#end
R2：
R2#conf t
R2(config)#router eigrp 123
R2(config-router)#eigrp router-id 2.2.2.2
R2(config-router)#no auto-summary
R2(config-router)#net 20.2.2.0 0.0.0.255
R2(config-router)#net 12.12.12.0 0.0.0.255
*Mar 1 00:15:25.031: %DUAL-5-NBRCHANGE: IP-EIGRP(0) 123: Neighbor 12.12.12.1 (Ethernet0/0) is up: new adjacency //检测到同属eigrp 123的邻居R2
R2(config-router)#net 23.23.23.0 0.0.0.255
R2(config-router)#end
R3：
R3#CONF T
R3(config)#router eigrp 123
R3(config-router)#eigrp router-id 3.3.3.3
R3(config-router)#no auto-summary
R3(config-router)#net 30.3.3.0 0.0.0.255
R3(config-router)#net 23.23.23.0 0.0.0.255
*Mar 1 00:18:57.075: %DUAL-5-NBRCHANGE: IP-EIGRP(0) 123: Neighbor 23.23.23.2 (Ethernet0/1) is up: new adjacency
R3(config-router)#end
步骤三：测试连通性
第一种方法：show ip eigrp neighbors
R2#show ip eigrp neighbors
IP-EIGRP neighbors for process 123
H Address Interface Hold Uptime SRTT RTO Q Seq
(sec) (ms) Cnt Num
1 23.23.23.3 Et0/1 12 00:03:20 51 306 0 3
0 12.12.12.1 Et0/0 12 00:08:13 92 552 0 4
第二种方法：ping
R3#ping 10.1.1.1 so 30.3.3.3
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.1.1.1, timeout is 2 seconds:
Packet sent with a source address of 30.3.3.3
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 64/92/108 ms
第三种办法：show ip eigrp topology
R2#show ip eigrp topology //拓扑表：所有可抵达的网络的路径信息
IP-EIGRP Topology Table for AS(123)/ID(2.2.2.2)
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 409600 //feasible distance(度量值)
via 12.12.12.1 (409600/128256), Ethernet0/0 //通过某个路由器
P 12.12.12.0/24, 1 successors, FD is 281600
via Connected, Ethernet0/0
P 20.2.2.0/24, 1 successors, FD is 128256
via Connected, Loopback0
P 23.23.23.0/24, 1 successors, FD is 281600
via Connected, Ethernet0/1
P 30.3.3.0/24, 1 successors, FD is 409600
via 23.23.23.3 (409600/128256), Ethernet0/1
实验B:手动汇总实验
B.0)实验目的：
熟悉手动汇总的现象和了解手动汇总的作用
B.1)拓扑图 （同实验A）
B.2) 实验步骤
步骤一：基本ip地址配置（同实验A）
步骤二：加入eigrp路由协议（同实验A）
步骤三：测试连通性（同实验A）
步骤四：开始手动汇总：
R2：
R2#conf t
R2(config)#int e0/1
R2(config-if)#ip summary-address EIGRP 123 10.0.0.0 255.0.0.0
R2(config-if)#END
手动汇总产生的系统路由à谁做的汇总谁就有系统路由。
系统路由为避免额外查找和黑洞，NULL0就是指这个路由丢弃

！！补充实验
1）eigrp hello 发送间隔及保持时间
！.1.0)实验目的：
发送间隔和保持时间对 eigrp 邻接关系的影响（偏学术）

！.1.2) 实验步骤
步骤一：基本ip地址配置（同实验A）
步骤二：加入eigrp路由协议（同实验A）
步骤三：测试连通性（同实验A）
步骤四：改变hello发送间隔和保持时间
R3#conf t

只有直连是可通的，但是加入路由协议，路由协议不通！
EIGRP RID相同不影响邻接关系建立
HOLDTIME
AS号不一致，邻接关系一定不建立
认证不通过，邻接关系一定不建立
邻居5K值必须一致 show ip protocols
K1=带宽 K2=负载 K3=延迟 K4=可靠性 K5=MTU

配置：
不等价负载均衡值
所有路径（最大路径/最小路径）取整（向下取）+1
步骤四：设置不等价负载均衡值
R1#conf t
R1(config)#router eigrp 123
R1(config-router)#variance 2
R1(config-router)#end
不等价负载均衡审查条件
1）不等价负载均衡链路总数不能超过默认的4
Router eigrp 123
Maxmum-paths ? <1-16>
2）不等价负载均衡次优路径AD必须小于FDMIN
3）不等价负载均衡值乘以FDMIN要大于所有次优路径FD
步骤五：修改延迟满足不等价均衡的条件
R2#show int s0/1 | in DLY
MTU 1500 bytes, BW 1544 Kbit, DLY 20000 usec,
R2#CONF T
R2(config)#int s0/1
R2(config-if)#delay 1999 //数值自动乘10
R2(config-if)#end
检测：show ip route eigrp（30.3.3.0从23.23.23.3走）
实验F:EIGRP末梢设置（EIGRP STUB）
SIA：卡在激活状态
EIGRP Stub 是避免 SIA最佳方案
R1#conf t
R1(config)#router eigrp 123
R1(config-router)#eigrp stub connected summary redistributed
EIGRP Stub 控制路由更新和发送
