vrrp description
To assign a description to the VRRP virtual router, use the vrrp description command in Interface Configuration mode. To return to the default, use the no format of the command.
Syntax
vrrp vrid description text no vrrp vrid description
Parameters
- vrid—Virtual router identifier on the interface for which VRRP is being defined. The range is 1-255.
- text—Text that describes the purpose or use of the virtual router. The parameter may contain 0-160 characters.
Default Configuration No description.
Command Mode
Interface Configuration mode
Example
The following example shows how to assign a VRRP description to the specified VRRP virtual router:
switchxxxxxx(config)# interface vlan 10switchxxxxxx(config-if)# vrrp 1 description router1switchxxxxxx(config-if)# exit |
vrrp ip
To define an IP address of a virtual router, use the vrrp ip command in Interface Configuration mode. To remove the IP address, use the no format of the command.
Syntax
vrrp vrid ip ip-address
no vrrp vrid ip [ip-address]
Parameters
- vrid—Virtual router identifier on the interface for which VRRP is being defined. The range is 1-255.
- ip-address—Virtual router’s IP address.
Command Mode
Interface Configuration mode
User Guidelines
A virtual router comes into existence when it has one or more participating VRRP routers. To participate in a specific virtual router as a VRRP router, use vrrp ip to configure an existing IP interface with the identifier and the IP address(es) of the virtual router. The IP interface of the VRRP router and the virtual router must be in the same IP subnet.
A VRRP router that is the owner if the virtual router’s IP address(es) is also the VRRP router real IP address at the IP interface. There is only one owner for all virtual router’s IP address(es). A VRRP router participates in a virtual router when it is configured with the first virtual router’s IP address and does not participate when the virtual router IP address is removed.
A virtual router entity in a VRRP router is created in the shutdown state. Use the no vrrp shutdown command to enable it.
To defined more than one virtual router’s IP address, the command should be applied for each configured IP address.
Each VRRP router in the virtual router should be configured with the same set of IP addresses.
If the ip-address parameter is omitted in the no format of the CLI command, all the IP addresses of the virtual router are removed, leading to the virtual router entity in the VRRP router being removed too.
The switch supports up to 255 VRRP routers.
Example
The following example shows how to define a VRRP virtual router:
switchxxxxxx(config)# interface vlan 10switchxxxxxx(config-if)# vrrp 1 ip 192.168.2.1switchxxxxxx(config-if)# exit |
vrrp preempt
To enable Virtual Router Redundancy Protocol (VRRP) preemption, use the vrrp preempt command in Interface Configuration mode. To return to the default, use the no format of the command.
Syntax vrrp vrid preempt no vrrp vrid preempt
Parameters
- vrid—Virtual router identifier on the interface for which VRRP is being defined. The range is 1-255.
Command Mode
Interface Configuration mode
Default Configuration
Preemption is enabled by default.
User Guidelines
By default, the VRRP router being configured with this command will take over as Master virtual router for the group if it has a higher priority than the current master virtual router.
Note: The router that is the IP address owner will preempt, regardless of the setting of this command.
Example
The following example shows how to disable VRRP preemption to the specified VRRP virtual router:
switchxxxxxx(config)# interface vlan 10switchxxxxxx(config-if)# no vrrp 1 preemptswitchxxxxxx(config-if)# exit |
vrrp priority
To define Virtual Router Redundancy Protocol (VRRP) priority, use the vrrp priority command in Interface Configuration mode. To return to the default, use the no format of the command.
Syntax
vrrp vrid priority priority no vrrp vrid priority
Parameters
- vrid—Virtual router identifier on the interface for which VRRP is being defined. The range is 1-255.
- priority—Virtual router priority. The range is 1-254.
Command Mode
Interface Configuration mode
Default Configuration
The default for owner is 255 and for non-owner it is 100.
User Guidelines
The priority of the owner cannot be changed. It is always 255.
Example
The following example shows how to set VRRP priority:
switchxxxxxx(config)# interface vlan 10switchxxxxxx(config-if)# vrrp 1 priority 110switchxxxxxx(config-if)# exit |
vrrp shutdown
To disable the VRRP virtual router on the interface (meaning that it changes its status to Initialize), use the vrrp shutdown command in Interface Configuration mode. To return to the default, use the no format of the command.
Syntax vrrp vrid shutdown no vrrp vrid shutdown
Parameters
- vrid—Virtual router identifier on the interface for which VRRP is being defined. The range is 1-255.
Default Configuration Disabled.
Command Mode
Interface Configuration mode
User Guidelines
When a VRRP virtual router is disabled on an interface, its configuration is not removed.
Example
The following example shows how to enable a specified virtual router:
switchxxxxxx(config)# interface vlan 10switchxxxxxx(config-if)# no vrrp 1 shutdownswitchxxxxxx(config-if)# exit |
vrrp source-ip
To define a real VRRP address that will be used as the source IP address of VRRP messages, use the vrrp source-ip command in Interface Configuration mode. To return to the default, use the no format of the command.
Syntax
vrrp vrid source-ip ip-address no vrrp vrid source-ip Parameters
- vrid—Virtual router identifier on the interface for which VRRP is being defined. The range is 1-255.
- ip-address—VRRP router’s IP address: one of IP addresses of VRRP router defined on the same interface.
Default Configuration
Lowest VRRP router’s IP address defined on the interface.

vrrp timers advertise
To define the interval between successive advertisements by the Master VRRP virtual router, use the vrrp timers advertise command in Interface Configuration mode. To return to the default, use the no format of the command.
Syntax
vrrp vrid timers advertise [msec] interval no vrrp vrid timers advertise
Parameters
- vrid—Virtual router identifier on the interface for which VRRP is being defined. The range is 1-255.
- msec—(Optional) Changes the unit of the advertisement time from seconds to milliseconds. Without the keyword, the advertisement interval is in seconds.
- interval—Time interval between successive advertisements. If keyword msec is present then the valid range is 50 to 40950 milliseconds. If keyword msec is omitted then the valid range is 1 to 40 seconds.
Command Mode
Interface Configuration mode
Default Configuration
1 second
User Guidelines
If the advertisement interval is configured in msec, the operation advertisement interval will be the configured advertisement interval round down to the nearest seconds for VRRP v2 and to the nearest centiseconds (10ms) for VRRP v3.
Example
The following example shows how to set VRRP timer advertise of 500 msec to specified VRRP virtual router:
switchxxxxxx(config)# interface vlan 10switchxxxxxx(config-if)# vrrp 1 timers advertise msec 500switchxxxxxx(config-if)# exit |

Parameters
- vrid—Virtual router identifier on the interface for which VRRP is being defined. The range is 1-255.
- 2—VRRPv2 specified by RFC3768 is supported. Received VRRPv3 messages are dropped by the VRRP virtual router. Only VRRPv2 advertisements are sent.
- 3—VRRPv3 specified by RFC5798 is supported without VRRPv2 support (8.4, RFC5798). Received VRRPv2 messages are dropped by the VRRP virtual router. Only VRRPv3 advertisements are sent.
- 2&3—VRRPv3 specified by RFC5798 is supported with VRRPv2 support (8.4, RFC5798). Received VRRPv2 messages are treated by the VRRP virtual router. VRRPv3 and VRRPv2 advertisements are sent.
Default Configuration Version 2.
Command Mode
Interface Configuration mode
User Guidelines
Version 2&3 is intended for upgrade scenarios and is not for permanent deployment. Please refer to VRRP 3 standard for version 2 and version 3 interoperability.
Example
The following example shows how to define VRRP version to specified VRRP virtual router:
