网络拓扑图如下:
组网说明:
本案例采用H3C HCL模拟器来模拟多vpn-instance实例RIP典型组网配置,为了实现不同VLAN之间通过不同的vpn实例进行隔离,因此采用多vpn实例捆绑到相应的VLAN。
VLAN 400与用于在SW1 、SW2的vpn-rt互联使用,VLAN 500用于SW1、SW2的vpn-nrt互联使用。由于VLAN 400与VLAN 500绑定到了不同的VPN实例,因此可以共同使用10.0.0.0/30作为互联地址。
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RIP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RIP,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。
