Disclosed herein are example embodiments for Boarder Gateway Protocol (BGP) signaling in virtual private network (VPN) communications. For example, a first network element may encode Multiprotocol Label Switching (MPLS) information in a Network Layer Reachability Information (NLRI) label field that is longer than 24 bits, and transmit a BGP update message comprising a BGP attribute to a second network element. The BGP attribute comprises the NLRI and a specific Subsequent Address Family Identifier (SAFI) value. The specific SAFI value signals to the second network element, upon reception of the BGP update message by the second network element, that the NLRI label field is more than 24 bits long.

The invention provides a method for extending a switch port, comprising the following steps: acquiring a media access control (MAC) address of a port which is perceived by uncontrolled bridging equipment; applying for a new tag to controlled bridging equipment, such as a service virtual local area network (VLAN) tag (s-tag); and storing a correspondence between the MAC address of the port which is perceived by the uncontrolled bridging equipment and a VLAN identification (ID) value in the applied s-tag. The embodiment of the invention also provides a device for extending the switch port.
