create vrrp vrid
Purpose To create a VRRP router on the Switch.
Syntax vrid <vrid 1-255> <ipif_name 12> ipaddress <ipaddr> {state [enable | disable] | priority
<int 1-254> | advertisement_interval <int 1-255> | preempt [true | false] | critical_ip
<ipaddr> | critical_ip_state [enable | disable]}
Description This command is used to create a VRRP interface on the Switch.
Parameters vrid <vrid 1-255> – Enter a value between 1 and 255 to uniquely identify this VRRP group on the Switch.All
routers participating in this group must be assigned the same vrid value.This value MUST be different from
other VRRP groups set on the Switch.
<ipif_name 12> – Enter the name of a previously configured IP interface that you wish to create a VRRP entry
for.This IP interface must be assigned to a VLAN on the Switch.
ipaddress <ipaddr> – Enter the IP address that will be assigned to the VRRP router.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.
state [enable | disable] – Used to enable and disable the VRRP IP interface on the Switch.
priority <int 1-254> – Enter a value between 1 and 254 to indicate the 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.)
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 create a VRRP entry:

11.1.1.1 state enable priority 200 advertisement_interval 1
preempt true critical_ip 10.53.13.224 critical_ip_state
e n a b l e
Command: create vrrp vrid 1 ipif Darren ipaddress 11.1.1.1
state enable priority 200 advertisement_interval 1 preempt
true critical_ip 10.53.13.224 critical_ip_state enable
