/cfg/l3/vrrp/vrgroup
Virtual Router Group Menu
The options described here allow for the failover of individual groups of VIRs and VSRs. When Web hosting is shared between two or more customers on a single Alteon VRRP, you can group VIRs and VSRs to serve the high availability of a specific customer. If failover occurs on a customer link, the group of VIRs and VSRs associated with that customer alone will fail over to the backup Alteon. The VIRs and VSRs configured for the other customers on the primary Alteon are not affected.
Up to 16 virtual router groups can be configured.
Note: Virtual Router Group failover requires that you enable preemption for the group using the /cfg/l3/vrrp/vrgroup/preem command.

Virtual Router Group Menu Options (/cfg/l3/vrrp/vrgroup) 
Command Syntax and Usage
track
 
Displays the VRRP Priority Tracking menu for this virtual router group. To view this menu, see /cfg/l3/vrrp/group/track Virtual Router Group Priority Tracking Configuration.
Tracking is a proprietary extension to VRRP used for modifying the standard priority system for electing the primary router.
name
 
Defines the virtual router group name.
Values: 1 – 8 characters
add <virtual router number (1-1024)>
 
Adds a virtual router to the group. Each virtual router group can have up to 64 virtual routers.
rem <virtual router number (1-1024)>
 
Removes a virtual router from the group.
prio <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 set to 255 (highest).
When priority tracking is used (/cfg/l3/vrrp/vrgroup #/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.
trackvr <virtual router number (0-1024)>
 
Defines the virtual router in the group that acts as the main virtual router. If the main virtual router fails, the entire group fails.
Values:
*0 — Specifies no main virtual router. If a virtual router in the primary state changes to the init state (due to VLAN, interface, or port failure), the peer virtual router assumes the primary role, even though other virtual routers in the same group are in the backup state. All virtual routers in the same service-based virtual router group are usually in the same state.
*1 – 1024 — Specifies the main virtual router. The main virtual router is responsible for sending advertisements on behalf of all other virtual routers in the same vrgroup. If the trackvr option is not configured, each virtual router individually sends its own advertisements with the vrgroup priority.
Default: 0
adver <1-255 seconds>
 
Sets the advertisement interval for the group.
preem disable|enable
 
Enables or disables preemption for the group.
share disable|enable
 
Enables or disables sharing for the group.
ena
 
Enables the virtual router group.
dis
 
Disables the virtual router group.
del
 
Deletes the virtual router group.
cur
 
Displays the current VRRP virtual router group configuration.
