1.1.6 vrrp authentication-mode
Syntax
vrrp authentication-mode authentication-type authentication-key
undo vrrp authentication-mode
View
VLAN interface view
Parameter
authentication-type: Authentication type. There are following types:
l simple: Indicates to perform simple character authentication.
l md5: Indicates to perform the AH authentication with MD5 algorithm.
authentication-key: The key cannot exceed 8 characters.
Description
Use the vrrp authentication-mode command to configure the authentication type and key of a specified VRRP virtual router.
Use the undo vrrp authentication-mode command to reset the authentication type and key of a specified VRRP virtual router.
If the simple or md5 authentication is configured, it is required to set the authentication key.
This command is used to configure the authentication type and key for all the VRRP virtual routers on an interface. As defined in the protocol, all the virtual routers on an interface shall use the same authentication type and key. And all the members joining the same virtual router shall also use the same authentication type and key.
Note that the authentication key is case sensitive.
Example
# Specify the authentication type and key for a VRRP virtual router.
[H3C-vlan-interface2] vrrp authentication-mode simple H3C
1.1.7 vrrp method
Syntax
vrrp method { real-mac | virtual-mac }
undo vrrp method
View
System view
Parameter
real-mac: Uses the real MAC address of the interface to match the virtual IP address of the virtual router in VRRP backup.
virtual-mac: Uses the virtual MAC address of the interface to match the virtual IP address of the virtual router in VRRP backup.
Description
Use vrrp method command to set correspondence between the MAC address and the virtual IP address of the virtual router: matching the real MAC address or the virtual address with the virtual IP address.
Use the undo vrrp method command to reset the correspondence to the default value.
By default, the switch matches the virtual MAC address with the IP address of the virtual router.
Due to the chips installed, some switches support matching one IP address to multiple MAC addresses. Then you may configure correspondence between the virtual IP address of the virtual router and the real/virtual MAC address.
You should set correspondence between the IP address of the virtual router and the MAC address before configuring the virtual router. Otherwise, you cannot configure the correspondence.
If you set correspondence between the IP address of the virtual router and the real MAC address, then you can configure only one virtual router on VLAN interface.
Example
# Set the real MAC address of the interface match the virtual IP address of the virtual router.
[H3C] vrrp method real-mac
1.1.8 vrrp ping-enable

View
System view
Parameter
None
Description
Use vrrp ping-enable command to enable the function to ping the virtual IP address of the virtual router.
Use the undo vrrp ping-enable command to disable the function.
By default, the ping function is disabled.
You can only use the commands before configuring any virtual router. If a virtual router is already established on the switch, it is not allowed to use the vrrp ping-enable command the undo vrrp ping-enable command to modify the configuration any more.
Example
# Enable to ping the virtual IP address of the virtual router.
[H3C] vrrp ping-enable
1.1.9 vrrp un-check ttl
Syntax
vrrp un-check ttl
undo vrrp un-check ttl
View
VLAN interface view
Parameter
None
Description
Use the vrrp un-check ttl command to disable the check of TTL value of VRRP packet. Use the undo vrrp un-check ttl command to enable the check of TTL value of VRRP packet.
The TTL value must be 225. If the Backup switch finds TTL is not 225 when receiving VRRP packet, the packet will be discarded.
By default, the switch checks TTL value of VRRP packets.
Example
# Disable to check TTL value of VRRP packet.
[H3C-vlan-interface2] vrrp un-check ttl
1.1.10 vrrp vrid preempt-mode
Syntax

undo vrrp vrid virtual-router-ID preempt-mode
View
VLAN interface view
Parameter
virtual-router-ID: VRRP virtual router ID, ranging from 1 to 255.
delay-value: Delay in seconds, ranging from 0 to 255.
Description
Use the vrrp vrid preempt-mode command to configure the preemption and delay of the virtual router.
Use the undo vrrp vrid preempt-mode command to cancel the preemption.
By default, virtual router is in preempt mode and delay-value is 0 second.
If a higher-priority switch is required to preempt the Master, you need to configure it as preemption. You can also set a delay for the preemption. If you configure it not to preempt, the delay will be set to 0 automatically.
Example
# Configure the switch to preempt.
[H3C-vlan-interface2] vrrp vrid 1 preempt-mode
# Set a delay.
[H3C-vlan-interface2] vrrp vrid 1 preempt-mode timer delay 5
# Configure the switch not to preempt.
[H3C-vlan-interface2] undo vrrp vrid 1 preempt-mode
1.1.11 vrrp vrid priority
Syntax
vrrp vrid virtual-router-ID priority priority
undo vrrp vrid virtual-router-ID priority
View
VLAN interface view
Parameter
virtual-router-ID: VRRP virtual router ID, ranging from 1 to 255.
priority: Priority value, ranging from 1 to 254; By default, the priority value is 100.
Description
Use the vrrp vrid priority command to configure the virtual router priority.
Use the undo vrrp vrid priority command to remove the virtual router priority.
The priority decides the status of a switch in the virtual router. A higher-priority switch is more likely to be a Master. Priority 0 is reserved for some special purpose. 255 is reserved for the IP address owner. The priority of the IP address owner is always 255 and cannot be modified.
Example
# Set the virtual router priority on VLAN-interface2.
[H3C-vlan-interface2] vrrp vrid 1 priority 120
1.1.12 vrrp vrid timer
Syntax

undo vrrp vrid virtual-router-ID timer advertise
View
VLAN interface view
Parameter
virtual-router-ID: VRRP virtual router ID, ranging from 1 to 255.
adver-interval: VRRP packet interval of the Master in the virtual router in seconds, ranging from 1 to 255; By default, the value is 1s.
Description
Use the vrrp vrid timer command to set the time interval for the Master in the virtual router to send VRRP packets.
Use the undo vrrp vrid timer advertise command to restore the default value.
You are supposed to set the identical timer value for the switches in the same virtual router to avoid wrong configuration.
Example
# Configure the Master to transmit VRRP packets every 15 seconds.
[H3C-vlan-interface2] vrrp vrid 1 timer advertise 15
1.1.13 vrrp vrid track
Syntax
vrrp vrid virtual-router-ID track vlan-interface interface-number [ reduced value-reduced ]
undo vrrp vrid virtual-router-ID track [ vlan-interface interface-name ]
View
VLAN interface view
Parameter
virtual-router-ID: VRRP virtual router ID, ranging from 1 to 255.
vlan-interface interface-number: Interface which is to be tracked.
value-reduced: Reduced value of priority, ranging from 1 to 255; By default, the reduced value of priority is 10.
Description
Use the vrrp vrid track command to configure the switch to track the interface.
Use the undo vrrp vrid track command to stop tracking the interface.
VRRP interface track expends the backup function, which thereby can be implemented not only when the switch fails, but also when the state of a network interface is Down. The user can use this command to track or stop tracking an interface or all the interfaces. After the command is configured, the priority of the switch will be reduced, if the state of the tracked interface goes Down. Accordingly, some other switch in the virtual router will have the comparatively highest priority and become the new Master, thereby implementing the backup function. The IP address owner does not allow the configuration of interface tracking.
Each virtual router can track up to 8 interfaces.
Example
# Set to track vlan-interface1 on vlan-interface2, and lower the priority of virtual router 1 on vlan-interface2 by 50 when the state of vlan-interface1 goes Down.
[H3C-vlan-interface2] vrrp vrid 1 track vlan-interface 1 reduced 50
1.1.14 vrrp vrid virtual-ip
Syntax
vrrp vrid virtual-router-ID virtual-ip ip-address

View
VLAN interface view
Parameter
virtual-router-ID: VRRP virtual router ID, ranging from 1 to 255.
ip-address: Virtual IP address.
Description
Use the vrrp vrid virtual-ip command to create a virtual router or add a virtual IP address to an existing virtual router.
Use the undo vrrp vrid virtual-ip command to cancel an existing virtual router or an address from the virtual router.
You can add up to 16 virtual IP addresses to one virtual router.
If all of the addresses in a virtual router are deleted, the system will delete the virtual router automatically.
Example
# Create a virtual router.
[H3C-vlan-interface2] vrrp vrid 1 virtual-ip 10.10.10.10
# Add a virtual IP address to an existing virtual router.
[H3C-vlan-interface2] vrrp vrid 1 virtual-ip 10.10.10.11
# Delete a virtual IP address.
[H3C-vlan-interface2] undo vrrp vrid 1 virtual-ip 10.10.10.10
# Delete a virtual router.
[H3C-vlan-interface2] undo vrrp vrid 1
