HUAWEI NetEngine80E/40E Router
Configuration Guide - Reliability
By default, VRRP smooth switching is enabled, and the interval carried in the VRRP packet is
100 seconds.
Before running the command, you must enable the function of learning the interval for receiving
VRRP packets. When the learning function is disabled, VRRP smooth switching is also disabled.

4.9.3 Checking the Configuration

By viewing the status of a VRRP backup group, you can check whether the configurations are
successful.
Prerequisite
The configurations of the VRRP smooth switching function are complete.
Procedure
Step 1 Run the
command to check the status of the VRRP backup group.
----End
Example
After configuring VRRP smooth switching, perform the AMB/SMB switchover on the device.
During the AMB/SMB switchover, the status of the VRRP backup group does not switch, and
thus the user traffic is not affected. After the AMB/SMB switchover, all VRRP configurations
of the new AMB are consistent with those of the original AMB.

NOTE
l If the interval set by the master router for sending VRRP broadcast packets is much greater than the
interval set by the backup router, the backup router resets the "masterdown" time after the backup
router is restarted and the interface recovers. The master router may not send packets after the
"masterdown" time of the backup router expires. In this case, the backup router becomes the master
router. As a result, two master routers exist.
l During the AMB/SMB switchover, the master router sends VRRP smooth switching packets at the
configured interval. If the time configured by the master router for VRRP smooth switching, such as
1s, is shorter than the configured interval for sending VRRP broadcast packets, such as 10s, VRRP
packets are sent at the interval of 10s, and the interval carried in the VRRP packet is 1s. As a result,
the status of the backup router continuously flaps.
