配置Multi-VPN-Instance CE（IPv6）示例
通过在CE上使用OSPF多实例实现局域网不同业务的隔离。
组网需求
分公司A（Site1）与分公司B（Site2）需要通过运营商的骨干网和总公司相互通信。分公司A和分公司B各自负责不同的业务，且需要访问总公司的不同区域，这个区域可以是有业务联系的相关部门，也可以是不同的服务器，因此需要为分公司A和分公司B实现业务隔离。如果使用传统的BGP/MPLS IPv6 VPN技术，需要在总公司侧分别为分公司A和分公司B架设一台CE设备，导致成本偏高。为了解决这个问题，可以在总公司侧使用MCE技术，即在总公司侧使用一台MCE设备接入不同VPN的Site，实现业务隔离。如图8-20所示：
CE1和CE2为分公司A和分公司B的CE设备，分别属于vpna和vpnb。
MCE作为VPN多实例交换的设备接入总公司侧的vpna和vpnb的Site。
vpna和vpnb使用不同的VPN-Target属性。
DeviceA和DeviceB分别为总公司内用于与分公司A和分公司B通信的设备。
要求属于相同VPN的用户之间能互相访问，不同VPN的用户之间不能互相访问。
配置注意事项
在配置过程中，需注意以下事项：
MCE上需要配置不同的VPN实例，并分别绑定不同的接口。
本例中PE与MCE间通过配置OSPFv3多实例进程来交互路由，因此需要在MCE上配置不对路由环路进行检查。
配置思路
采用如下思路配置Multi-VPN-Instance CE：
PE与PE之间配置OSPF实现PE之间的互通、配置MP-IBGP交换VPN路由信息。
PE与相连的CE之间建立BGP4+对等体，把VPN路由引入PE的VPN路由表中。
MCE与PE2之间配置OSPFv3多实例，交换VPN路由信息。
MCE与DeviceA、DeviceB之间配置RIPng交换VPN路由信息。
MCE与PE2之间配置OSPFv3多实例时需进行以下配置。
在PE2的OSPFv3视图下（该OSPFv3进程是指在MCE与PE2之间配置OSPFv3多实例时所使用的OSPFv3进程）引入BGP路由，发布PE1的私网路由给MCE。
在PE2的BGP-VPN实例IPv6地址族视图下引入该OSPFv3进程（也是指在MCE与PE2之间配置OSPFv3多实例时所使用的OSPFv3进程），发布MCE的私网路由信息给PE1上。
数据准备
为完成此配置例，需准备如下的数据：
在PE1、PE2及MCE上为每个相互隔离的业务创建VPN实例vpna和vpnb，vpna的出方向和入方向的VPN-Target值为111:1，vpnb的出方向和入方向的VPN-Target值为222:2
配置OSPFv3所需数据（为不同业务配置OSPF多实例时所使用的OSPF进程号应互不相同），vpna的OSPFv3多实例进程号为100，vpnb的OSPFv3多实例进程号为200
在MCE上为引入Site3、Site4的VPN路由所使用的RIPng进程，vpna的RIPng多实例进程号为100，vpnb的RIPng多实例进程号为200
操作步骤
- 在骨干网的PE上配置OSPF协议，实现PE之间的互通
具体配置过程请参见后面的配置文件。
完成此步配置后，PE之间应能互相学习到对方的Loopback1的地址。
以PE2为例：
<PE2> display ip routing-table
Route Flags: R - relay, D - download to fib, T - to vpn-instance, B - black hole route ------------------------------------------------------------------------------ Routing Table : _public_ Destinations : 9 Routes : 9 Destination/Mask Proto Pre Cost Flags NextHop Interface 1.1.1.1/32 OSPF 10 1 D 172.16.1.1 GigabitEthernet1/0/0 2.2.2.2/32 Direct 0 0 D 127.0.0.1 LoopBack1 127.0.0.0/8 Direct 0 0 D 127.0.0.1 InLoopBack0 127.0.0.1/32 Direct 0 0 D 127.0.0.1 InLoopBack0 127.255.255.255/32 Direct 0 0 D 127.0.0.1 InLoopBack0 172.16.1.0/24 Direct 0 0 D 172.16.1.2 GigabitEthernet1/0/0 172.16.1.2/32 Direct 0 0 D 127.0.0.1 GigabitEthernet1/0/0 172.16.1.255/32 Direct 0 0 D 127.0.0.1 GigabitEthernet1/0/0 255.255.255.255/32 Direct 0 0 D 127.0.0.1 InLoopBack0
- 在骨干网的PE上配置MPLS基本能力和MPLS LDP，PE之间建立LDP LSP
具体配置过程请参见后面的配置文件。
完成此步配置后，在PE上执行命令display mpls ldp session，应能看见PE之间的MPLS LDP会话状态为“Operational”。
以PE2为例：
<PE2> display mpls ldp session
LDP Session(s) in Public Network Codes: LAM(Label Advertisement Mode), SsnAge Unit(DDDD:HH:MM) An asterisk (*) before a session means the session is being deleted. -------------------------------------------------------------------------- PeerID Status LAM SsnRole SsnAge KASent/Rcv -------------------------------------------------------------------------- 1.1.1.1:0 Operational DU Active 0000:00:07 32/32 -------------------------------------------------------------------------- TOTAL: 1 Session(s) Found. - 在PE设备上配置VPN实例，将CE1、CE2接入PE1，将MCE接入PE2

完成上述配置后，在MCE设备上执行命令display ipv6 routing-table vpn-instance命令，可以看到去往对端CE的路由。
