3.18.9 Example for Configuring Multi-VPN-Instance CE
By using OSPF multi-instance on CEs, you can implement service isolation on the LAN.
Networking Requirements
As shown in Figure 3-10, the networking requirements are as follows:
l CE1 and CE2 belong to the same LAN, and MCE, CE3, and CE4 belong to the same LAN.
l An MCE is used by the client to exchange routes between multiple VPN instances.
l CE1 and CE3 belong to vpna, while CE2 and CE4 belong to vpnb.
l vpna and vpnb use different VPN targets.
The users residing in the same VPN can mutually access, but those in different VPNs cannot
mutually access. So, the services of different VPNs in LAN are isolated from each other.
