1.  Summary

This project implements VRRP (Virtual Router Redundancy Pro-
tocol)  version  3 for IPv4 and IPv6, and VRRP version 2 for
IPv4.   The  VRRP  protocol  provides  high-availability  of
static  IP  routing services by allowing multiple routers to
cooperate to dynamically detect failures and  fail  services
over to available backup routers.

2.  Decision & Precedence Information

The project is approved as specified in references [1-7].

The project may be delivered in a Patch release  of  the  ON
consolidation.

3.  Interfaces

The project exports the following interfaces.
