config vrrp vrid
router priority. The VRRP Priority value may determine if a higher
priority VRRP router overrides a lower priority VRRP router. A higher
priority will increase the probability that this router will become the
Master router of the group. A lower priority will increase the
probability that this router will become the backup router. VRRP
routers that are assigned the same priority value will elect the
highest physical IP address as the Master router. The default value
is 100. (The value of 255 is reserved for the router that owns the IP
address associated with the virtual router and is therefore set
automatically.)
ipaddress <ipaddr>
- Enter the virtual IP address that will be
assigned to the VRRP entry. This IP address is also the default
gateway that will be statically assigned to end hosts and must be set
for all routers that participate in this group.
advertisement_interval <int 1-255>
- Enter a time interval value, in
seconds, for sending VRRP message packets. This value must be
consistent with all routers participating within the same VRRP group.
The default is 1 second.
preempt [true | false]
– This entry will determine the behavior of
backup routers within the VRRP group by controlling whether a
higher priority backup router will preempt a lower priority Master
router. A true entry, along with having the backup router’s priority set
higher than the masters priority, will set the backup router as the
Master router. A false entry will disable the backup router from
becoming the Master router. This setting must be consistent with all
routers participating within the same VRRP group. The default
setting is
true
.
critical_ip <ipaddr>
- Enter the IP address of the physical device that
will provide the most direct route to the Internet or other critical
network connections from this virtual router. This must be a real IP
address of a real device on the network. If the connection from the
virtual router to this IP address fails, the virtual router will be disabled
automatically. A new master will be elected from the backup routers
participating in the VRRP group. Different critical IP addresses may
be assigned to different routers participating in the VRRP group, and
can therefore define multiple routes to the Internet or other critical
network connections.
critical_ip_state [enable | disable]
– This parameter is used to enable
or disable the critical IP address entered above. The default is
disable
.
Restrictions Only
administrator-level users can issue this command.
Example usage:
To configure a VRRP entry:
DES-3800:4#config vrrp vrid 1 ipif Trinity state enable
priority 100 advertisement_interval 2
Command: config vrrp vrid 1 ipif Trinity state enable priority
100 advertisement_interval 2
Success.
