A multi-VPN-instance CE (MCE) device can connect to multiple VPNs. The MCE solution isolates services of different VPNs while reducing cost of network devices.
Before configuring an MCE device, complete the following tasks:
Configure VPN instances on the MCE and PE connected to it (one instance for each service).
Configure the link layer protocol and network layer protocol for LAN interfaces and connect the LAN to the multi-instance CE (each service using an interface to access the multi-instance CE).
Bind related VPN instances to the interfaces of the multi-instance CE and PE interfaces through which the PE accesses the multi-instance and configure IP addresses for those interfaces.
