说明，由于在cisco的IOS中团体属性默认使用十进制的方式，为了方便查看使用ip bgp-community new-format使之转换为AS:NN格式

ip bgp-community new-format

由于BGP的团体属性是可选属性，需要手动在BGP路由协议进程下使能

router bgp 65000
bgp router-id 192.168.1.1
bgp cluster-id 192.168.1.1
bgp log-neighbor-changes

BGP团体属性包含三种类型，如下图：

给路由打团体属性步骤如下：

（1）先使用ip prefix匹配路由条目

!
ip prefix-list as65001-import-yewu seq 1 permit 10.95.1.0/24
ip prefix-list as65001-import-yewu seq 2 permit 10.95.2.0/24
ip prefix-list as65001-import-yewu seq 3 permit 10.95.3.0/24

（2）创建route-map匹配设定的ip prefix，打团体属性

route-map as65001-export permit 10
match ip address prefix-list as65001-bangong
set community 65001:100
!
route-map as65001-export permit 20
match ip address prefix-list as65001-yewu
set community 65001:200
!

route-map as65001-export permit 30
!

（3）创建route-map匹配设定的ip prefix，打团体属性

neighbor internal route-map as65001-export out
关于route-map调用的方向，in方向表示接收路由的时候给相应的路由打团体属性，out表示发布路由的时候给相应的路由打团体属性。
