Configure a LAN interface as a Layer 3 interface

A LAN interface cannot be directly configured as Layer 3 interface, and Layer 3 functions are implemented via the VLANIF interface. The VLANIF interface is a logical Layer 3 interface. After an IP address is configured for the VLANIF interface, the device will add the MAC address and VID entry of the VLANIF interface to a MAC address table, and sets the Layer 3 forwarding mark to a bit for the entry. If the destination MAC address of a packet matches the entry, the packet will be forwarded to Layer 3 to implement Layer 3 interconnection between VLANs.
