SR6600路由器
MPLS L3VPN 及 OSPF Sham-Link功能的配置
关键词:SR66;MPLS;BGP;VPN;OSPF多实例;Sham-Link
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,PEB连接vpna站点2出口CEB,PEA与CEA、PEB与CEB通过OSPF多实例学习CEA下挂站点路由,CEA和CEB有一条旁路,要求PEA和PEB的OSPF多实例建立伪连接
设备清单:SR6600路由器4台
二、组网图:
三、配置步骤:
设备和版本:SR6600

四、配置关键点:
1) 在vpna站点间存在旁路时需要建立伪连接;
2) PEA和PEB需要建立vpna的loopback口用于建立伪连接;
