A Multi-Protocol Label Switching (MPLS) edge router includes: a label information table storage unit adapted to store NextHop information to route a label packet to an Internet Protocol (IP) network and interface information to transmit the label packet to a NextHop; an Internet Protocol routing module adapted to manage and maintain the label information table storage unit; and an MPLS forwarding engine adapted to delete a label by accessing the label information table storage unit and searching the interface information and the NextHop information stored therein, and transmitting an IP packet to the corresponding interface upon receiving the label packet to be transmitted to the IP network.
