Abstract Abstract
This memo defines the Virtual Router Redundancy Protocol (VRRP). This memo defines the Virtual Router Redundancy Protocol (VRRP).
VRRP specifies an election protocol that dynamically assigns VRRP specifies an election protocol that dynamically assigns
responsibility for a virtual router to one of the VRRP routers on a responsibility for a virtual router to one of the VRRP routers on a
LAN. The VRRP router controlling the IP address(es) associated with LAN. The VRRP router controlling the IP address(es) associated with
a virtual router is called the Master, and forwards packets sent to a virtual router is called the Master, and forwards packets sent to
these IP addresses. The election process provides dynamic fail over these IP addresses. The election process provides dynamic fail over
in the forwarding responsibility should the Master become in the forwarding responsibility should the Master become
