MSR系列路由器
MPLS L3VPN + ISIS多实例配置
关键词:MSR;MPLS;BGP;VPN;ISIS多实例
一、组网需求:
2台PE各接着一个vpna的站点,PEA连接vpna站点1出口CEA,PEA与CEA通过ISIS多实例学习CEA下挂站点路由
设备清单:MSR系列路由器3台
二、组网图:
三、配置步骤:
设备和版本:MSR系列、Version 5.20, Release 1509

四、配置关键点:
配置需要注意:
1. ISIS视图下Network-Entity Title的配置;
2. 接口视图下使能ISIS进程;
3. PEA的BGP和ISIS进程的vpn路由要互相引入。
