Pseudowire Redundancy Service Models

This section describes the various MC-LAG and pseudowire redundancy scenarios as well as the
algorithm used to select the active transmit object in a VLL endpoint.
The redundant VLL service model is described in the following section,
Model.

Redundant VLL Service Model

In order to implement pseudowire redundancy, a VLL service accommodates more than a single
object on the SAP side and on the spoke SDP side.
VLL service based on the concept of endpoints.
A VLL service supports by default two implicit endpoints managed internally by the system. Each
endpoint can only have one object, a SAP or a spoke SDP.
