   (e.g. /usr/man/man8)

it requires to be run as root.

Usage: vrrpd -i ifname -v vrid [-f piddir] [-s] [-a auth] [-p prio] [-nh] ipaddr
  -h       : display this short inlined help
  -n       : Dont handle the virtual mac address
  -i ifname: the interface name to run on
  -v vrid  : the id of the virtual server [1-255]
  -s       : Switch the preemption mode (Enabled by default)
  -a auth  : (not yet implemented) set the authentification type
             auth=(none|pass/hexkey|ah/hexkey) hexkey=0x[0-9a-fA-F]+
  -p prio  : Set the priority of this host in the virtual server (dfl: 100)

Linux Server S1 Details
-----------------------------
eth0 is connected to LAN switch. IP Address Binded to eth0 is 192.168.100.22
eth1 is connected to Internet Router.

Linux Server S2 Details
-----------------------------
eth0 is connected to LAN switch. IP Address Binded to eth0 is 192.168.100.44
eth1 is connected to Internet Router.

I started vrrpd daemon on S1 & S2 using the following command-

On Server S1: vrrpd -i eth0 -v 1 -p 255 192.168.100.22        ( MASTER)

On Server S2: vrrpd -i eth0 -v 1 -p 200 192.168.100.22         (Backup)

This way 192.168.100.22 became the Virtual IP of Virtual Router with VRID = 1.
