The purpose of this working group is to define and develop a standard
  virtual router redundancy protocol for IPv4 and IPv6.  A virtual
  router redundancy protocol is a protocol which allows several 
  routers on a multiaccess link to utilize the same virtual IP address. 
  One router will be elected as a master with the other routers acting as
  backups in case of the failure of the master router.  The primary
  motivation to using a virtual router redundancy protocol is that host
  systems may be configured (manually or via DHCP) with a single default
  gateway, rather than running an active routing protocol.  The protocol
  should also support the ability to load share traffic when both routers
  are up.
   The goals of this working group are:
   1. Define and develop a standard virtual router redundancy protocol
      for IPv4 and IPv6.
   2. Develop VRRP MIB(s).
   3. Separate specifications will be developed for IPv4 and IPv6.
   4. Determine whether static (configuration based) load sharing is
      adequate or if some amount of dynamic load sharing is required.
   5. Working group will examine security issues to determine what
      security threats it is appropriate for the VRRP protocol to 
      handle and include the appropriate mechanisms in the VRRP protocol.
    6. The internet draft "Virtual Router Redundancy Protocol"
       (draft-hinden-vrrp-00.txt) will be use as the basis of virtual
       router redundancy protocol.  The working group will also consider 
       other Internet-Drafts related to this topic allowing for issues 
       regarding change control, security, running code, etc.
     7. Intellectual property issues regarding the technology to
        develop a virtual router redundancy protocol will be identified
        and addressed.
