VRRP/HiVRRP Configuration

With this dialog you can enter general settings and settings for each port for the VRRP.
You can configure

General settings

Parameter

Meaning

Operation

Switch the VRRP function on and off

Version

Display the VRRP version

Send VRRP Master Trap

As soon as the router takes over the VRRP master function, it sends a master trap

Send VRRP Authentication Failure Trap

As soon as the router receives a VRRP message with an incorrect authentication, it sends a VRRP authentication error trap.

Parameter

Meaning

Port

Port to which this entry applies

VRID

Virtual router ID (value 1-255)

Function

Switch the VRRP instances on and off

State

VRRP state
initialize: VRRP is in the initialization phase. No master has been named yet.
backup: The router sees the possibility of becoming master.
master: The router is master.

Priority

VRRP priority set (value: 1-255; default: 100).
The router with the highest value takes over the master function. If the virtual router IP address is the same as the IP address of the router interface, then this router is the “owner”. If an owner exists, then VRRP assigns the owner the VRRP priority 255 and thus declares it the master.

Current Priority

VRRP priority actually used (value: 1-255). This value is usually the same as the VRRP priority set, but it can be smaller if monitored tracking objects have the “down” status.

VRRP IP address

Primary virtual router IP address.

HiVRRP
Advert Interval[ms]

Interval for sending out messages (advertisements) as the master (value for VRRP: 1-255 s,
value for HiVRRP: 100-255,000 ms,
default setting: 1 s).

Preempt mode

This setting specifies whether this router, as a backup router, will take over the master role from a master router with a lower VRRP priority. If the preempt mode is switched off, this router only takes on the master role if the IP Multicast message from the existing master does not appear.

Preempt
Delay[s]

The preempt mode, in collaboration with VRRP tracking, can enable a switch to a better router. However, dynamic routing procedures take a certain amount of time to react to changed routes and refill their routing table. To avoid the loss of packets during this time, delayed switching (preempt delay) from the master router to the backup router enables the dynamic routing procedure to fill the routing tables (value: 0-65535 s, default setting 0 s).

Domain ID

The domain ID is a number identifying the domain (refer HiVRRP Domains).
Value: 0-8, default setting 0 = no domain.

Domain Role

none: not a member of a domain
member: copies the behavior of the supervisor
supervisor: determines the behavior of the domains

Authentication Type

Type of authentication used:
noAuthentication: VRRP information is exchanged without authentication.
simpleTextPassword: VRRP information is exchanged with plain text password authentication.

Authentication Key

Password for authentication.
In order to communicate, the routers with the same virtual router IP address must have the same authentication setting.

Master IP Address

Actual router interface IP address of the master.

Setting up the VRRP router instance

Note: As the IP address owner has the fixed VRRP priority 255 by definition, the VRRP tracking function requires the IP addresses of the VRRP router interfaces to differ from the virtual router IP address.
Note: Activate the preempt mode so that, the backup router can take over the master role after the decrementation of the master’s VRRP priority via the tracking function.
