VRRP configuration commands Support for VRRP commands depends on the device model. For more information, see About the Command References for HP Unified Wired-WLAN Products. The interfaces that VRRP involves can be only VLAN interfaces. The term "router" in this document refers to both routers and routing-capable HP wireless products. display vrrp Use display vrrp to display the state information of VRRP groups.
IPv4 Standby Information: Run Mode : Standard Run Method : Virtual MAC Total number of virtual routers : 1 Interface VRID State Run Adver Auth Virtual Pri Timer Type IP --------------------------------------------------------------------Vlan2 1 Master 140 1 Simple 1.1.1.1 Table 1 Command output (standard mode) Field Description Current VRRP working mode: • Standard—Standard mode. • Load Balance—Load balancing mode.
Virtual MAC : 0000-5e00-0101 Master IP : 1.1.1.2 VRRP Track Information: Track Interface: Vlan3 State : Down Pri Reduced : 10 Track Object State : Positive Pri Reduced : 50 : 1 Table 2 Command output (standard mode) Field Description Current VRRP working mode: Run Mode • Standard—Standard mode. • Load Balance—Load balancing mode.
Field Description Virtual IP Virtual IP address of the VRRP group. Virtual MAC Virtual MAC address that corresponds to the virtual IP address of the VRRP group. It is displayed only when the router is in master state. Master IP Primary IP address of the interface where the router in master state resides. VRRP Track Information Information about the tracked interface or object. It is displayed only when the vrrp vrid track or vrrp vrid track interface command is executed.
Table 3 Command output (load balancing mode) Field Description Current VRRP working mode: • Standard—Standard mode. • Load Balance—Load balancing mode. Run Mode Current VRRP running mode: • Real MAC—Real MAC mode, which means the virtual IP address of the VRRP group is mapped to the real MAC address of the interface. Run Method • Virtual MAC—Virtual MAC mode, which means the virtual IP address of the VRRP group is mapped to the virtual MAC address.
Virtual IP : 10.1.1.1 Member IP List : 10.1.1.2 (Local, Master) 10.1.1.
Field Description Status of the router in the VRRP group: State • Master. • Backup. • Initialize. Config Pri Configured priority of the router, that is, the priority value specified by using the vrrp vrid priority command. Running Pri Running priority of the router, that is, the current priority of the router. With VRRP tracking configured, the priority of the router changes if the state of the monitored interface or track entry changes.
Field Description Pri Reduced Priority value that is reduced when the monitored interface is down or removed, or when the status of the monitored track entry turns to negative. It is displayed only when the vrrp vrid track interface command or the vrrp vrid track command is executed. Switchover Switchover mode. When the status of the monitored track entry turns to negative, the backup immediately switches to the master.
Field Description A track entry has the following states: State • • • • Invalid. Negative. Positive. Not existing. IP address of the member device. Member IP If the status of the monitored track entry turns to negative and the local device has an LVF whose corresponding AVF is on the specified member device, the LVF immediately becomes active. display vrrp statistics Use display vrrp statistics to display statistics about VRRP groups.

Usage guidelines If you specify both an interface and a VRRP group, the statistics about the specified VRRP group on the specified interface are cleared. If you specify only the interface, the statistics about all the VRRP groups on the interface are cleared. If you specify neither, the statistics about all the VRRP groups on the router are cleared. Examples # Clear the statistics about all the VRRP groups on the router.
vrrp mode Use vrrp mode to configure the VRRP working mode. Use undo vrrp mode to restore the default. Syntax vrrp mode load-balance undo vrrp mode Default VRRP operates in standard mode. Views System view Default command level 2: System level Parameters load-balance: Specifies the load balancing mode. Usage guidelines • When you configure the working mode of VRRP by using this command, both IPv4-based and IPv6-based VRRP groups operate in the specified mode.
Default TTL check on VRRP packets is enabled. Views Interface view Default command level 2: System level Usage guidelines The master of a VRRP group periodically sends VRRP advertisements to indicate its existence. The VRRP advertisements are multicast onto the local network segment and not forwarded by a backup router, and therefore the packet TTL value will not be changed. When the master of a VRRP group advertises VRRP packets, it sets the packet TTL to 255.
cipher: Sets a ciphertext authentication key. key: Sets the authentication key. This argument is case sensitive. • When md5 authentication applies, it must be a plaintext string of 1 to 8 characters or a ciphertext string of 24 characters if the cipher keyword is not specified, or a ciphertext string of 1 to 41 characters if the cipher keyword is specified.
Parameters virtual-router-id: Virtual router ID or VRRP group number in the range of 1 to 255. timer delay delay-value: Sets preemption delay. The delay-value argument is in the range of 0 to 1800 seconds, and the default is 0 seconds.
The role that a router plays in a VRRP group depends on its priority. A higher priority means that the router is more likely to become the master. Priority 0 is reserved for special use and 255 is for the IP address owner. If the router is the IP address owner, its priority is always 255. Therefore, it remains as the master so long as it is functioning correctly. Examples # Set the priority of VRRP group 1 on VLAN-interface 2 to 150.
[Sysname-Vlan-interface2] vrrp vrid 1 virtual-ip 10.1.1.1 [Sysname-Vlan-interface2] vrrp vrid 1 timer advertise 5 Related commands display vrrp vrrp vrid track Use vrrp vrid track to associate a VRRP group with a track entry and control master switchover or AVF switchover in the VRRP group in response to changes (such as uplink state changes) detected by the track entry. Use undo vrrp vrid track to remove the association between a VRRP group and a track entry.
When the track entry changes from negative to positive or invalid, the router automatically restores its priority. You must create the VRRP group and assign a virtual IP address to it before you can associate it with any track entry. The vrrp vrid track command cannot take effect on an IP address owner. If you have configured the command on an IP address owner, the configuration takes effect after the router changes to be a non-IP address owner.
reduced priority-reduced: Value by which the priority decrements. The priority-reduced argument is in the range of 1 to 255, and the default is 10. Usage guidelines When the uplink interface of a router in a VRRP group fails, usually the VRRP group cannot be aware of the uplink interface failure. If the router is the master of the VRRP group, hosts on the LAN are not able to access external networks because of the uplink failure. This problem can be solved through tracking a specified uplink interface.
Default command level 2: System level Parameters virtual-router-id: VRRP group number in the range of 1 to 255. virtual-address: Virtual IP address. Usage guidelines The system removes a VRRP group after you delete all the virtual IP addresses in it. The virtual IP address of a VRRP group cannot be 0.0.0.0, 255.255.255.255, loopback address, non A/B/C address and other illegal IP addresses such as 0.0.0.1.
Parameters virtual-router-id: VRRP group number in the range of 1 to 255. track track-entry-number: Specifies a track entry to be monitored by its number in the range of 1 to 1024. reduced weight-reduced: Specifies the value by which the weight decreases, in the range of 1 to 255. The default setting is 30. Usage guidelines The command is effective only when VRRP operates in load balancing mode.
