NAME
vrrpd
– Virtual Router Redundancy Protocol Daemon
SYNOPSIS
vrrpd -i ifname -v vrid [-f piddir] [-s] [-a auth] [-p prio]
[-nhb] [-I ifname] [-d delay] [-m address] [-M ] [-B]
[-S script] [-c conf_file] [-D level] ipaddr
DESCRIPTION
vrrpd
is an implementation of Virtual Redundant Routing Protocol (VRRPv2) as specified in
RFC2338. It runs in Linux user space. In short, VRRP is a protocol that elects a Master server on
a LAN to which the Master answers to a
virtual IP address
. If it fails, a Backup server takes over
the IP address.
VRRP specifies an election protocol that dynamically assigns responsibility for a virtual router to
one of the VRRP routers on a LAN. The VRRP router controlling the IP address(es) associated
with a virtual router is called the Master, and forwards packets sent to these IP addresses. The
election process provides dynamic failover in the forwarding responsibility should the Master
become unavailable. This allows any of the virtual router IP addresses on the LAN to be used as
the 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.
OPTIONS
The following options are supported by vrrpd:
- h display the usage line
-n
Don’t use the virtual MAC address
-b
Run vrrpd in foreground
-i <ifname>
the interface name on which to run the Virtual
Router. Machines connected with the named interface will see
the Virtual Router Address move with the Master switch
-I <ifname>
the interface name on which to communicate
with other VRRP routers for management of the Virtual Router
(default is the -i interface)
-v <vrid> the id of the Virtual Router Identifier [1-255].
This value must be a unique value, one per Virtual Router. In
other words there is a unique vrid to ifname associated with
