最佳答案
您好,请知:
以下是多VPN实例OSPF的配置案例,请参考:
业务地址、互联地址、Loopback地址如拓扑图所示。其中VLAN 10、VLAN 100属于vpn-rt中,VLAN 20、VLAN 200属于vpn-nrt实例中,另外SW1与SW2之间的互联采用trunk,互联的VLAN使用VLAN 400(绑定到vpn-rt)和VLAN 500(绑定到vpn-nrt),全网采用多VPN实例OSPF互联互通,不通VPN实例的业务地址不能互通。
vpn-rt规划如下:
RD:100:1
RT:100:1
vpn-nrt规划如下:
RD:200:1
RT:200:1
1、分别在SW1和SW2创建VPN实例
2、根据组网说明将各业务地址、互联地址、loopback绑定到vpn实例
3、创建多实例OSPF,并发布业务地址实现互通
4、SW1与SW2之间的互联采用trunk,仅允许互联的VLAN互通。
