Virtual Router Group Configuration
Virtual Router Group commands are used for associating all virtual routers into a single logical
virtual router, which forces all virtual routers on the
G8124 to either be master or backup as a group.
A virtual router is defined by its virtual router ID and an IP address. On each VRRP-capable routing
device participating in redundancy for this virtual router, a virtual router will be configured to share
the same virtual router ID and IP address.
Note – This option is required to be configured only when using at least two G8124s in a
hot-standby failover configuration, where only one switch is active at any time.
Table 236 VRRP Virtual Router Group Configuration Commands
Command Syntax and Usage
group virtual-router-id <1-128>
Defines the virtual router ID (VRID).
The VRID for standard virtual routers (where the virtual router IP address is not the same as
any virtual server) can be any integer between 1 and 128. All VRID values must be unique
within the VLAN to which the virtual router’s IP interface (see interface below) belongs.
The default virtual router ID is 1.
Command mode: Router VRRP
group interface <interface number>
Selects a switch IP interface. The default switch IP interface number is 1.
Command mode: Router VRRP
group priority <1-254>
Defines the election priority bias for this virtual router group. This can be any integer between
1 and 254. The default value is 100.
During the master router election process, the routing device with the highest virtual router
priority number wins. If there is a tie, the device 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 will automatically be set to 255 (highest).
When priority tracking is used, this base priority value can be modified according to a number
of performance and operational criteria.
