1.1.8 vrrp vrid preempt-mode

Syntax

vrrp vrid virtual-router-id preempt-mode [ timer delay delay-value ]

undo vrrp vrid virtual-router-id preempt-mode [ timer delay ]

View

VLAN Interface view

Parameter

virtual-router-id: Virtual router ID or VRRP standby group number, in the range 1 to 255.

timer delay: Sets preemption delay. In preemption mode, if you configure a preemption delay, the standby group member in the backup state will wait for the specified period of time before becoming the master.

delay-value: Preemption delay, in the range 0 to 255 seconds. It defaults to 0 seconds.

Description

Use the vrrp vrid preempt-mode command to enable preemption on the router and configure its preemption delay in the specified standby group.

Use the undo vrrp vrid preempt-mode command to disable preemption on the router in the specified standby group.

Use the undo vrrp vrid preempt-mode timer delay command to restore the default preemption delay, that is, zero seconds.

The default mode is immediate preemption without delay.

If you disable preemption, the delay period changes to zero seconds automatically.

On an instable network, the standby group member in the backup state may not normally receive the packets from the master member due to network congestion, resulting in frequent master/backup state transition of the standby group members. Preemption delay is introduced to solve this problem. With a preemption delay set, if the backup member does not receive the packet from the master member duly, it waits for a period to see whether it can receive any packet from the master. If the specified period elapses but it still receives no packet from the master, it becomes the master.

Example

# Configure the device to work in the preempt mode and set the preempt delay to five seconds.

<Sysname> system-view

[Sysname] interface vlan-interface 2

[Sysname-Vlan-interface2] vrrp vrid 1 preempt-mode timer delay 5

1.1.9 vrrp vrid priority

Syntax

vrrp vrid virtual-router-id priority priority-value

undo vrrp vrid virtual-router-id priority

View

VLAN Interface view

Parameter

virtual-router-id: VRRP standby group number, in the range 1 to 255.

priority-value: Priority value of the router in the specified standby group, in the range 1 to 254, with a higher number indicating a higher priority.

Description

Use the vrrp vrid priority command to configure the priority of the router in the specified standby group.

Use the undo vrrp vrid priority command to restore the default.

By default, the priority of a router in a standby group is 100.

In VRRP, the role that a router plays in a standby group depends on its priority. A higher priority means that the router is more likely to become the master. Note that priority 0 is reserved for special use and 255 for the IP address owner.

If the router is the IP address owner, its priority is always 255. Therefore, it will be the master so long as it is functioning normally.

Example

# Set the priority of standby group 1 to 150 on VLAN-interface 2.

<Sysname> system-view

[Sysname] interface vlan-interface 2

[Sysname-Vlan-interface2] vrrp vrid 1 priority 150

Parameter

virtual-router-id: VRRP standby group number, in the range 1 to 255.

adver-interval: Interval at which the master in the specified standby group sends VRRP packets. It ranges from 1 to 255 seconds.

Description

Use the vrrp vrid timer advertise command to configure the Adver_Timer of the specified standby group.

Use the undo vrrp vrid timer advertise command to restore the default.

By default the Adver_Timer is 1 second.

The Adver_Timer controls the interval at which the master sends VRRP packets.

Routers in the same VRRP standby group must use the same Adver_Timer setting.

Example

# Set the interval at which the master device in standby group 1 sends VRRP packets to five seconds.

l The tracked interface configured with the vrrp ipv6 vrid track command can be a VLAN interface or Tunnel interface, but cannot be the interface where the standby group is created.

Example

# On VLAN-interface 2, configure to track VLAN-interface 1, so that when VLAN-interface 1 turns down, the priority of standby group 1 on VLAN-interface 2 is reduced by 50.

<Sysname> system-view

[Sysname] interface vlan-interface 2

[Sysname-Vlan-interface2] vrrp ipv6 vrid 1 track interface vlan-interface 1 reduced 50

1.2.11 vrrp ipv6 vrid virtual-ip

Syntax

vrrp ipv6 vrid virtual-router-id virtual-ip virtual-address [link-local]

undo vrrp ipv6 vrid virtual-router-id [ virtual-ip virtual-address [ link-local ] ]

View

VLAN interface view

Parameter

virtual-router-id: VRRP standby group number, in the range 1 to 255.

virtual-address: Virtual IPv6 address.

link-local: Indicates that the virtual IPv6 address of the standby group is a link local address.

Description

Use the vrrp ipv6 vrid virtual-ip link-local command to assign the first virtual IPv6 address to the specified standby group. The first virtual IPv6 address assigned to a standby group must be a link local address and only one such address is allowed in a standby group.

Use the vrrp ipv6 vrid virtual-ip command to add a virtual IPv6 address to a standby group.

Use the undo vrrp ipv6 vrid command to remove a standby group.

Use the undo vrrp ipv6 vrid virtual-router-id virtual-ip virtual-address [ link-local ] command to remove a virtual IPv6 address from a standby group.

After you remove all virtual IPv6 addresses, the standby group is automatically removed. Note that the first address assigned to the group must be removed the last.

By default, no standby group exists.

Example

# Create standby group 1 and add virtual IPv6 address fe80::10.

<Sysname> system-view

[Sysname] interface vlan-interface 2

[Sysname-Vlan-interface2] vrrp ipv6 vrid 1 virtual-ip fe80::10

# Add the virtual IPv6 address 1::10 to standby group 1.

[Sysname-Vlan-interface2] vrrp ipv6 vrid 1 virtual-ip 1::10
