create vrrp vrid
Purpose
To create a VRRP router on the Switch.
Syntax
vrid <vrid 1-255> ipif <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 <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
router 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 or Operator-level users can issue this command.
