Virtual Router Redundancy (VRRP)
Netopia Firmware Version 8.6.1 offers Vir tual Router Redundancy Protocol (VRRP). A Vir tual Router is a 
software abstraction consisting of a group of two or more hardware routers protecting one or more IP 
addresses. One of the routers is designated as the Master, while the others are backups. VRRP is a protocol 
that provides redundancy to routers within a local area network by allowing alternate paths for a PC without 
changing the IP address or MAC address by which the PC knows its gateway.
To configure Vir tual Routers, from the IP Setup screen select VRRP Options and press Return.
The Ethernet LAN VRRP Options screen appears.
Each logical IP inter face can have a maximum of two Vir tual Routers.
Select Add Virtual Router and press Return.
