TE隧道功能验证
CH09到CH03建立MPLS TE隧道(CH09-6509-CH03)， 通过配置静态路由使Testcenter2打Testcenter1的5000条BGP网段流量都经过该TE隧道。（www.61k.com]
crs-058 CRS-1实验指南
CH09相关配置如下：
router static
address-family ipv4 unicast
192.168.10.2/32 tunnel-te1 ！所有到5000条BGP路由的下一跳均是192.168.10.2， 所以把到192.168.10.2下一跳设置为tunnel-te1,即可实现把该流量导入到TE隧道中。（www.61k.com) !
!
在testcenter建立流， 源端口TEN10/2, 目的端口TEN10/1，流源地址是TEN10/2接口地址，目的地址是TEN10/1放出的5000条BGP路由。

二 : 1个人的CCIE
有些人看似在跑，其实是逃，要学会跑，必须要有内心的渴望。
想念。真的不是名词。
是1种想起来就想哭的心情。
我希望，LOVE AND CCIE。可以互不干扰的共存。
我不能接受最终我没拿到那个水晶牌子。
我不能接受最终我失去了这份心痛的想念的心情。
爱。是含笑饮毒酒。
只有真正爱过的人，才能说出这样的话吧。
这不是华丽的辞藻，是深刻。
是不是想念1个人之际。
并不一定是心在想念。
而是眼睛想念对方的样子。
手指（www.61k.com）想念与他的手指相握的感觉。
亦或是身体想念对方身上的温度呢。
你一定为他做过不理智的事。
你一定陪他谈论过盛大的梦想。
你一定就那么坚信过他是你的下半生。
那个少年。
他是有缺点的。
但在你眼里。
他胜过所有光芒。
我说起你的淡如水，说起你的漫不经心，说起你的冷若星，埋怨你如何马耳东风，投诉你让我对牛弹琴。当我陈列你一切缺点时，却发现自己成为一座想念的博物馆。----------------------------------------
It is the time you have wastered foryourrose,thatmake her so important.CCIE就是这朵rose，你越是为它付出过时间，越是为它投入过精力，越是为它放弃过所爱，它就越是你心中求之不得，弃之不舍的隐痛。三 : CRS-1实验指南

TE隧道功能验证
CH09到CH03建立MPLS TE隧道(CH09-6509-CH03)， 通过配置静态路由使Testcenter2打Testcenter1的5000条BGP网段流量都经过该TE隧道。
CH09相关配置如下：
router static
address-family ipv4 unicast
192.168.10.2/32 tunnel-te1 ！所有到5000条BGP路由的下一跳均是192.168.10.2， 所以把到192.168.10.2下一跳设置为tunnel-te1,即可实现把该流量导入到TE隧道中。 !
!
在testcenter建立流， 源端口TEN10/2, 目的端口TEN10/1，流源地址是TEN10/2接口地址，目的地址是TEN10/1放出的5000条BGP路由。

可以看到流量均从TE1/6/0/0的出去，此端口即为tunne的起始端口， MPLS-TE工作正常。
MPLS TE FRR快速重路由
在上一个MPLS TE实验中， CH09已经建立了一条TUNNEL TE1， CH09->65->CH03，在本实验项目中，需要建立一条备用通路TUNNEL2， CH09->CH03， 当主用通路断掉时候，流量可以快速切换到TUNNEL2上。
建立备用tunnel2

从以上可以看到FRR已经READY，在打流的过程中， 进入65交换机， shutdown 65的端口TEN 1/3
从测试仪的流量指针上看，流量只会丢十几毫秒即完成切换。
