1 流量统计典型配置举例

1.1  适用产品和版本

适用于8048、8062产品系列R6728版本。

1.2  组网需求

如图1-1所示，

·     在Router A和Router C之间使用LDP动态建立LSP，使11.1.1.0/24和21.1.1.0/24这两个网段中互访的报文通过MPLS进行标签转发。

·     Router A、Router B和Router C上只允许目的地址为1.1.1.9/32、2.2.2.9/32、3.3.3.9/32、11.1.1.0/24和21.1.1.0/24的路由表项触发LDP建立LSP，其他路由表项不能触发LDP建立LSP。在Router B上配置倒数第二跳不弹出功能。

·     在Router A、Router B和Router C上对从源网段11.1.1.0/24到目的网段21.1.1.0/24的流量进行流量统计，以检查丢包的链路。

‌

设备	接口	IP地址	设备	接口	IP地址
Router A	Loop0	1.1.1.9/32	Router B	Loop0	2.2.2.9/32
	GE1/0/1	10.1.1.1/24		GE1/0/1	10.1.1.2/24
	GE1/0/2	11.1.1.1/24		GE1/0/2	20.1.1.1/24
Router C	Loop0	3.3.3.9/32
	GE1/0/1	20.1.1.2/24
	GE1/0/2	21.1.1.1/24
