VRRP and VRRP-E parameters (Continued) TABLE 125
Parameter Description Default
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
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 can have priority from 6
through 255.
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).
