VRRP and VRRPE parameters
17
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 page 459
page 467
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 464
page 466
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 464
page 466
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 468
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 468
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the Master for the VRID before determining that the Master is no
longer active.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 469
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 469
