问题描述:

我想要一个关于路由器vpn实例的案例

就隔离一下接口就行

谢谢大佬

组网及组网描述:


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 10VLAN 100属于vpn-rt中,VLAN 20VLAN 200属于vpn-nrt实例中,另外SW1SW2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


配置步骤

1、分别在SW1SW2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、SW1SW2之间的互联采用trunk,仅允许互联的VLAN互通。

配置关键点

请参考以下配置:

创建vpn实例:

ip vpn-instance Manager
route-distinguisher 1:1
vpn-target 1:1 import-extcommunity
vpn-target 1:1 export-extcommunity
#

接口绑定vpn实例:

interface M-GigabitEthernet0/0/0
ip binding vpn-instance Manager
ip address 192.168.1.32 255.255.255.0
