Cisco ASR 1000 VxLAN Support
First Published: November 21, 2012
This module contains information about VxLAN (Virtual eXtensible Local Area Network) Layer 2
gateway feature support on the Cisco ASR 1000 Series Routers. VxLAN is a technology that provides a
Layer 2 overlay network, allowing for network isolation. The standard 802.1q VLAN implementation
limits the number of tags to 4096. However, cloud service providers may want to operate more than 4096
virtual networks. VxLAN uses a 24-bit network ID, which allows for a much larger number of individual
i networks to be operated.
