VRRP and VRRP-E parameters
Authentication
type
The type of authentication the VRRP or VRRP-E interfaces
use to validate VRRP or VRRP-E packets.
•
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.
•
HMAC-MD5-96 (VRRP-E only) – The interface uses
HMAC-MD5-96 authentication for VRRP-E packets.
NOTE: HMAC-MD5-96 authentication is only supported
for IPv4 or IPv6 VRRP-E. HMAC-MD5-96 is not
supported by VRRP. Authentication is not
supported for VRRP v3.
No authentication
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.
VRRP-E – All routers
for the VRID are
Backups.
Backup priority
A numeric value that determines a Backup router’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 (backups) can have a priority from 3
through 254.
•
VRRP-E – 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 v2 and IPv6
VRRP v3 - The value
is 255 for the Owner
and 100 for the
Backups.
VRRP-E v2 and IPv6
VRRP-E v3 -The value
is 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.
NOTE: Suppression of RIP advertisements is not
supported for VRRP v3 and VRRP-E v3.
Disabled
Hello interval
The number of seconds or milliseconds between Hello
messages from the Master to the Backups for a given
VRID. The interval can be from 1 through 84 seconds for
VRRP v2, VRRP-E v2, and IPv6 VRRP-E. The interval for
VRRP v3 can be from 100 through 8400 milliseconds.
One second (VRRP
v2 and VRRP-E v2,
and IPv6 VRRP-E)
1000 milliseconds
(VRRP v3).
