Displaying and
Maintaining VRRP for
IPv4-Based VRRP
Configuration
Example
Single VRRP Standby
Group Configuration
Example
To do...
Enter system view
Enter the specified interface view
Configure the authentication
mode and authentication key
when the standby groups send
and transmit VRRP packets
Configure the time interval for the
Master in the standby group to
send VRRP advertisement
You may configure different authentication modes and authentication keys for the
standby groups on an interface. However, the members of the same standby
group must use the same authentication mode and authentication key.
Factors like excessive traffic or different timer setting on routers can cause the
Backup timer to time-out abnormally and change the state. To solve this problem,
you can prolong the time interval to send VRRP packets and configure a delay for
preemption.

Network requirements
Host A needs to access Host B on the Internet, using 202.38.160.111/24 as its
■
default gateway.
Router A and Router B belong to standby group 1 with the virtual IP address of
■
202.38.160.111.
If Router A operates normally, packets sent from Host A to Host B are
■
forwarded by Router A; if Router A fails, packets sent from Host A to Host B are
forwarded by Router B.

IPv4-Based VRRP Configuration Example

Use the command...
system-view
