Cisco ASR 9000 Series Configuration Guidelines

CHAPTER 6
Implementing Multipoint Layer 2 Services
This module provides the conceptual and configuration information for Multipoint Layer 2 Bridging Services,
also called Virtual Private LAN Services (VPLS).
VPLS supports Layer 2 VPN technology and provides transparent multipoint Layer 2 connectivity for customers.
This approach enables service providers to host a multitude of new services such as broadcast TV and Layer
2 VPNs.
Note
For Point to Point Layer 2 Services, see Implementing Point to Point Layer 2 Services chapter.
For descriptions of the commands listed in this module, see the “Related Documents” section. To locate
documentation for other commands that might appear while executing a configuration task, search online in
the Cisco IOS XR software master command index.
