Gurwinder Singh · 2015
MPLS is a technology that is used for fast packet forwarding mechanism within service provider networks. Labels are attached to packets and a label mapping is done from one edge router of provider to other edge router of provider. MPLS is used in Service Provider environments. Label Distribution protocols are used for label distribution and exchange of labels from one router to other router. Layer 2 VPNs behave like the customer sites are connected using Layer 2 switches. There are different Layer 2 VPN techniqu es like Virtual Private LAN Services (VPLS), Virtual Private Wire Service (VPWS) and Ethernet Virtual Private Network (EVPN). As MPLS runs inside Service Provider Networks. Security is always one of the major objectives. This paper explains the security technique s that can be applied to make Layer 2 MPLS secure.
