/cfg/l3/vrrp/group
Virtual Router Group Configuration
The options described here are used for associating all virtual routers into a single logical virtual router, which forces all virtual routers on the Alteon to either be primary or backup as a group. A virtual router is defined by its virtual router ID and an IP address. On each VRRP-capable routing Alteon participating in redundancy for this virtual router, a virtual router is configured to share the same virtual router ID and IP address.
Note: A switch-based virtual router group is required only when using at least two Alteons in a hot-standby failover configuration, where only one Alteon is active at any time.

VRRP Virtual Router Group Options (/cfg/l3/vrrp/group) 
Command Syntax and Usage
track
 
Displays the VRRP Priority Tracking menu for the virtual router group.
Tracking is a proprietary extension to VRRP, used for modifying the standard priority system used for electing the primary router. Tracking is not needed if sharing (the share option) is enabled.
ipver v4|v6
 
Sets the version of the Internet Protocol supported by the virtual router group.
Default: v4
vrid <virtual router ID (1-255)>
 
Defines the virtual router ID for this group.
if <interface number (1-256)>
 
Selects an Alteon IP interface.
Values: 1 – 256
Default: 1
prio <priority (1-254)>
 
Defines the election priority bias for this virtual router group.
During the primary router election process, the routing Alteon with the highest virtual router priority number wins. If there is a tie, the Alteon with the highest IP interface address wins. If this virtual router’s IP address (addr) is the same as the one used by the IP interface, the priority for this virtual router is automatically be set to 255 (highest).
When priority tracking is used (/cfg/l3/vrrp/track or /cfg/l3/vrrp/vr #/track), this base priority value can be modified according to a number of performance and operational criteria.
Values: 1 – 254
Default: 100
ospf
 
Updates the OSPF cost increment for this virtual router group. To disable OSPF cost adjustment, when prompted, enter the new cost increment as 0.
adver <1-255>
 
Defines the time interval between VRRP primary advertisements.
Values: 1 – 255 (for IPv4, in seconds; for IPv6, in centiseconds)
Default: 1 (IPv4), 100 (IPv6)
Note: Radware recommends that you use the default value of 100 or above for IPv6 interfaces to avoid a high load on the Alteon management CPU.
preem disable|enable
 
Enables or disables primary preemption. When enabled, if the virtual router group is in backup mode but has a higher priority than the current primary, this virtual router preempts the lower priority primary and assumes control.
Note: Even when preem is disabled, this virtual router always preempts any other primary if this Alteon is the owner (the IP interface address and virtual router addr are the same).
Default: enable
share disable|enable
 
Enables or disables virtual router sharing, a proprietary extension to VRRP. When enabled, this Alteon processes any traffic addressed to this virtual router, even when in backup mode.
Default: enable
ena
 
Enables the virtual router group.
dis
 
Disables the virtual router group.
del
 
Deletes the virtual router group.
Not available in vADC mode.
cur
 
Displays the current configuration information for the virtual router group.
