Configuration Commands

VRRP Virtual Router configuration

Virtual Router commands are used for configuring virtual routers for this switch. 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.

Virtual routers are disabled by default.

The following table describes the Virtual Router Configuration commands. Table 148 Virtual Router Configuration commands

Command	Description
virtual-router <1-250>	Defines the virtual router ID. This is used in conjunction with addr (below) to
virtual-router-id <1-250>	define a virtual router on this switch. To create a pool of VRRP-enabled
	routing devices which can provide redundancy to each other, each
	participating VRRP device must be configured with the same virtual router:
	one that shares the same virtual router ID and address
	combination.
	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 250.
	The default value is 1.
	All virtual router ID values must be unique within the VLAN to which
	the virtual router’s IP interface belongs.
	Command mode: Router VRRP
[no] virtual-router <1-250>	Defines the IP address for this virtual router using dotted decimal notation.
address <IP address>	This is used in conjunction with the vrid (above) to configure the same
	virtual router on each participating VRRP device. The default address is
	0.0.0.0.
	Command mode: Router VRRP
virtual-router <1-250>	Selects a switch IP interface. If the IP interface has the same IP address as
interface <1-249>	the address option above, this switch is considered the “owner” of the
	defined virtual router. An owner has a special priority of 255 (highest) and
	will always assume the role of master router, even if it must preempt another
	virtual router which has assumed master routing authority. This preemption
	occurs even if the preemption option below is disabled.
	The default value is 1.
	Command mode: Router VRRP
virtual-router <1-250>	Defines the election priority bias for this virtual server. This can be any
priority <1-254>	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.
	Command mode: Router VRRP
virtual-router <1-250>	Defines the time interval between VRRP master advertisements. This can be
timers advertise <1-255>	any integer between 1 and 255 seconds. The default value is 1.
	Command mode: Router VRRP
