实验二：
BGP团体配置
一、配置团体属性local_as
R4#conft.
R4（config）#ipprefix-list1permit4.4.4.0/24//定义前缀列表
R4（config）#route-mapLocal_ASpermit10//定义route-map
R4（config-route-map）#matchipaddressprefix-list1//匹配前缀列表
R4（config-route-map）#setcommunitylocal-AS//设置团体属性
R4（config-route-map）#routerbgp65002
R4（config-router）#neighbor3.3.3.3send-community//开启发送团体属性的能力
R4（config-router）#neighbor3.3.3.3route-mapLocal_ASout//再出方向向邻居发送团体属性
