    ENNI (External Network-Network Interface) ratified as MEF26 in January 2010 Defines Ethernet interconnection services between operators

    Simplifies provisioning and troubleshooting across multiple networks

    Implements point-to-point and multipoint services ENNI is based on Ethernet provider bridging

    Multiple customer services across a single ENNI
