Authentication
type
The type of authentication the VRRP or VRRPE
routers use to validate VRRP or VRRPE packets.
The authentication type must match the
authentication type the VRID’s port uses with other
routing protocols such as OSPF.
• No authentication – The interfaces do not use
authentication. This is the VRRP default.
• Simple – The interface uses a simple text-string
as a password in packets sent on the interface. If
the interface uses simple password
authentication, the VRID configured on the
interface must use the same authentication type
and the same password.
Note: MD5 is not supported by VRRP or VRRPE.
No authentication 22-5

Router type Whether the router is an Owner or a Backup.
• Owner (VRRP only) – The router on which the
real IP address used by the VRID is configured.
• Backup – Routers that can provide routing
services for the VRID but do not have a real IP
address matching the VRID.
VRRP – The Owner is
always the router that
has the real IP address
used by the VRID. All
other routers for the
VRID are Backups.
VRRPE – All routers
for the VRID are
Backups.
22-14
Backup priority A numeric value that determines a Backup’s
preferability for becoming the Master for the VRID.
During negotiation, the router with the highest priority
becomes the Master.
• VRRP – The Owner has the highest priority
(255); other routers can have a priority from 3 –
254.
• VRRPE – All routers are Backups and have the
same priority by default.
If two or more Backups are tied with the highest
priority, the Backup interface with the highest IP
address becomes the Master for the VRID.
VRRP – 255 for the
Owner; 100 for each
Backup
VRRPE – 100 for all
Backups

Suppression of
RIP
advertisements
A router that is running RIP normally advertises
routes to a backed up VRID even when the router is
not currently the active router for the VRID.
Suppression of these advertisements helps ensure
that other routers do not receive invalid route paths for
the VRID.
Disabled 22-15
Hello interval The number of seconds between Hello messages
from the Master to the Backups for a given VRID. The
interval can from 1 – 84 seconds.
One second 22-4
