组网及说明

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


配置步骤

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。
