Configuration Commands

Table 149 Virtual Router Priority Tracking Configuration commands

CommandDescription

[no] virtual-router <1-250> track interfaces

When enabled, the priority for this virtual router will be increased for each other IP interface active on this switch. An IP interface is considered active when there is at least one active port on the same VLAN. This helps elect the virtual routers with the most available routes as the master. This command is disabled by default.

Command mode: Router VRRP

[no] virtual-router <1-250> track ports

When enabled, the priority for this virtual router will be increased for each active port on the same VLAN. A port is considered active if it has a link and is forwarding traffic. This helps elect the virtual routers with the most available ports as the master. This command is disabled by default.

Command mode: Router VRRP

VRRP Virtual Router Group configuration

The Virtual Router Group commands are used for associating all virtual routers into a single logical virtual router, which forces all virtual routers on the switch 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.

The following table describes the Virtual Router Group Configuration commands. Table 150 Virtual Router Group Configuration commands

Command	Description
group virtual-router-id	Defines the virtual router ID.
<1-250>	The virtual router ID 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 250. All virtual router ID values must be unique
	within the VLAN to which the virtual router’s IP interface belongs. The default
	virtual router ID is 1.
	Command mode: Router VRRP
group interface <1-249>	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 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.
