L2VPN provides users the flexibility to scale bandwidth according to their needs. L2 Ethernet are preferred over L3 IP VPN for efficient transport of Non-IP applications including traditional voice and video, along with this, application security is an another L2 consideration as the customers can control their own routing tables.
