5、配置团体属性 一、实验拓扑 二、实验要求
1、按照图示配 IP 地址R2R3R4R5分别配 Loopbacke 口地址作为OSPF的Route_id和IBGP邻居地址地址格式为 x.x.x.x/32x为设备编号。R1 上配置Loopback口模拟业务网段
2、As 200内部配置OSPF仅用于实现BGP的TCP可达
3、AS 200内部建立BGP联盟联盟A为 AS 200包含2个子AS为 AS 6501 和 AS 65002。R1和R2建立EBGP邻居R4 和 R6 建立 EBGP邻居R2和R4建立EBGP邻居子AS内部建立IBGP全连接
4、R1把业务网段宣告进BGP要求AS 200内部所有路由器都能够学习到该业务网段路由
5、通过配置团体属性使 192.168.0.0/24 网段路由只能传递至 AS 200
