TCP/IP 6.4.2 非等价负载均衡
很感谢上帝！
是的
很感谢
阳光依旧是阳光
雨露依旧是雨露
天空依旧是天空
叶子依旧是叶子
真的是非常的不容易
在这么的天气有个人有着会笑的眼睛，陪着你，恩呢，就是幸福呀！
总觉得她的眼睛很亮
~
可以看透所有的一切，但是又是慈爱的
恩呢
~
怎么说呢
我能说亮晶晶吗，能说会发光吗，（有点妖魔化了）
感谢上帝
我把所有的都托付在我主的手中
我便安然
上帝加添给我全备的信心，我才敢摊开自己的掌心呀
6.4.2
非等价负载均衡
注意：
EIGRP
等价负载均衡这个地方找个做下
~~~
狗血的问题（
如同狗血的剧情）
EIGRP
最多在
16
条等价的路由路径上实现等价负载均衡。
EIGRP
也可以实现非等价负载均衡
解释名词：差异变量（
variance
）用来确定哪些路由在非等价负载均衡中是可以使用的。
任何路由的度量值如果超过了最小代价路由的度量值乘以
Variance
的值，那么这条路由将不被使用。
这个就是确认你数据包的负载的百分比，比如一条宽路走了
5
个包，另一条稍微窄路走
1
个包
非等价负载均衡
1、
不能超过
16
条
2、
AD
小于
FD
3、
FDmin*Varance
大于等于
FD
实验：非等价负载均衡
注意：
Top
、配置、
net
文件和抓包
串口的默认带宽是
1544kbit/s
基本配置，配完以后
Top
表
从
top
表中认为的最优路由才会放进路由表中
计算题出来了
FDmin*varance
大于
FD
V=5
所以
Earhart#sh run | be eigrp
router eigrp 100
variance 5
network 172.20.0.0
auto-summary
查看路由表
关掉
CEF
和快速交换，查看

没有做出书上的那种效果
~~ 5:1

哪有吗？
哪有吗？欺负人呀！
还是有哪位好心的大哥做出这个效果来着
