The Virtual Router Redundancy Protocol (VRRP) enables a virtual router composed of two or more VRRP routers on the same subnet to prevent failure by supplying at least one designated Standby virtual router if the designated Master virtual router fails. It is designed to eliminate the single point of failure most common in a static default routed environment. IP Infusion’s ZebOS® Advanced Routing Suite VRRP module provides for increased availability of the default gateway servicing hosts on the same subnet.

The VRRP specifieIP Infusion: ZebOSŪ Integrated Managements an election protocol that dynamically assigns responsibility for a virtual router to one of the VRRP routers on a LAN. The VRRP-enabled router controlling the IP addresses associated with a virtual router is called the Master, and it forwards packets sent to these IP addresses. The election process manages dynamic fail-over in the forwarding responsibility should the Master become unavailable. Any of the virtual router's IP addresses on a LAN can then be used as thIP Infusion: ZebOSŪ Layer 2 Switchinge default first-hop router by end-hosts. The advantage gained from using VRRP is a higher availability default path without requiring configuration of dynamic routing or router discovery protocols on every end-host.


Advantages of Virtual Router Redundancy

  • Reduces the administrative and processing overhead required when using a dynamic routing protocol on every end-host
  • Extensible security that requires minimal configuration
  • Provides IP address backup
  • Supports Preferred Path Indication (PPI)
  • Minimizes unnecessary service disruptions
  • Efficiently operates over extended LANs
