TABLE 103 VRRP and VRRP-E parameters (continued)
Parameter Description Default
NOTE
Authentication is not supported for
VRRP v3.
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).
Dead interval The number of seconds or milliseconds 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Master is no longer active.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.
If the value for the dead interval is not
configured, then the current dead interval is
equal to three times the Hello interval plus the
Skew time (where Skew time is equal to (256 -
priority) divided by 256).
Backup Hello interval The number of seconds between Hello
messages from a Backup to the Master. Disabled
60 seconds when enabled
