VRRP

The Virtual Router Redundancy Protocol (VRRP) is a computer networking protocol that provides for automatic assignment of available Internet Protocol (IP) routers to participating hosts. This increases the availability and reliability of routing paths via automatic default gateway selections on an IP sub network.

How to Use:

1. Go to Stack > Instances > (Select Instance) > VRRP

2. Configure your settings

3. Click Save

Description

NAME

Users can specify the user-friendly name for the setting.

INSTANCE STATE

Users can define the state of the instance. it should be either MASTER or BACKUP.

HA INTERFACE

Users can add the high available interface for redundancy.

DATA INTERFACE

Users can specify the data interfaces.

VIRTUAL ROUTER ID

Users can specify the virtual router ID for the setting.

PRIORITY

Users can set the priority for the setting.

MONITORING FREQUENCY

Users can set the monitoring frequency timeout value.

Enable VMAC

Users can enable or disable virtual MAC. A virtual MAC address is a floating entity shared by the primary and the secondary nodes in an HA setup.

Enable VMAC BASE

Users can enable or disable VMAC BASE.

Auth Type

Users can specify which type of authentication is being used.

Auth Password

When user has selected auth type to password, then user need to update the password in this field.

Virtual IPs

Users can specify the virtual IPs for the VRRP setting

Peer IPs

Users can specify the peer IPs to which machine will keep sending hello messages and verify they are up or not.

Excluded Virtual IPs

Users can specify the VIP which need to be excluded in advert. For cases with large numbers (eg 200) of IPs on the same interface. To decrease the number of addresses sent in adverts, you can exclude most IPs from adverts. Since all addresses in virtual_ipaddress must be of the same family.
