R2511-HP MSR Router Series High Availability Command Reference(V5)

67
Default command level
2: System level
Parameters
virtual-router-id: Specifies a VRRP group by its number in the range of 1 to 255.
track track-entry-number: Specifies a track entry by its number in the range of 1 to 1024.
forwarder-switchover member-ip ipv6-address: Enables the LVF on the router to take over the role of the
AVF at the specified IPv6 address immediately after the specified track entry changes to the negative
state. You can use the display vrrp verbose command to view the IPv6 addresses of VFs.
reduced priority-reduced: Reduces the priority of the router in the VRRP group by a specific value when
the state of the specified track entry changes to the negative state. The value range for the
priority-reduced argument is 1 to 255.
switchover: Enables the router in backup state to take over as the master immediately after the specified
track entry changes to the negative state.
Usage guidelines
When the associated track entry changes to the negative state, the priority of the router in the VRRP group
decreases by a specified value, or the router immediately takes over as the master if it is a backup router,
or the LVF on the router immediately takes over the role of the AVF at the specified IPv6 address,
depending on your configuration.
If forwarder-switchover member-ip ipv6-address, reduced priority-reduced, and switchover are not
specified, the priority of the router in the VRRP group decreases by 10 when the track entry changes to
negative.
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 ipv6 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.
You can create a track entry with the track command before or after you associate it with an IPv6 VRRP
group. For more information about configuring track entries, see High Availability Configuration Guide.
Examples
# Associate IPv6 VRRP group 1 on Ethernet 1/1 with track entry 1 and decrease the priority of the device
in the VRRP group by 50 when the state of track entry 1 changes to negative.
<Sysname> system-view
[Sysname] interface ethernet 1/1
[Sysname-Ethernet1/1] vrrp ipv6 vrid 1 virtual-ip fe80::2 link-local
[Sysname-Ethernet1/1] vrrp ipv6 vrid 1 track 1 reduced 50
# Associate VRRP group 1 on Ethernet 1/1 with track entry 2 and enable the LVF on the device to take
over the role of the AVF at the IP address of FE80::10 immediately after the specified track entry changes
to the negative state.
[Sysname-Ethernet1/1] vrrp ipv6 vrid 1 track 2 forwarder-switchover member-ip fe80::10
