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。 TCC测试脚本：LAB-mpls-te.tcc

观察6509, CH09, CH03 tunnel状态均为UP状态：

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。
