VRRP and VRRPE parameters
17
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. page 460
page 462
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 page 460

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 page 464
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 page 464
Dead interval The number of seconds a Backup waits for a Hello message from
the Master for the VRID before determining that the Master is no
longer active.
If the Master does not send a Hello message before the dead
interval expires, the Backups negotiate (compare priorities) to
select a new Master for the VRID. Three times the Hello
Interval plus one-half second page 464
Backup Hello interval The number of seconds between Hello messages from a Backup
to the Master.
The message interval can be from 60 – 3600 seconds.
You must enable the Backup to send the messages. The
messages are disabled by default on Backups. The current
Master (whether the VRRP Owner or a Backup) sends Hello
messages by default.
Disabled
60 seconds when enabled page 465
Track port Another device port or virtual interface whose link status is
tracked by the VRID’s interface.
If the link for a tracked interface goes down, the VRRP or VRRPE
priority of the VRID interface is changed, causing the devices to
renegotiate for Master. None page 454
