Configuring ANCP
Overview
This chapter describes how to configure Access Node Control Protocol (ANCP), also
known as Layer 2 Control (L2C), for IP multicast on an E Series router; it contains

Access Node Control Protocol (ANCP), also known as Layer 2 Control (L2C), is based
on a subset of the General Switch Management Protocol (GSMP), as defined in the
GSMPv3 Base Specification (draft-ietf-gsmp-v3-base-spec-06.txt). GSMP is a general
purpose protocol used to control a label switch.
GSMP enables a controller to establish and release connections across the switch,
add and delete leaves on a multicast connection, manage switch ports, request
configuration information, request and delete reservation of switch resources, and
request statistics. It also enables the switch to inform the controller of asynchronous
events such as a link going down.
Deploying value-added services across digital subscriber line (DSL) access networks
requires special attention to quality of service (QoS) and service control. This control
depends on tighter coordination between network elements in the broadband access
network while not causing added burden to the operations support system (OSS)
layer.
