Complete these tasks to configure VRRP for IPv4:
Task
Remarks
Configuring a VRRP operation mode
Optional.
Specifying the type of MAC addresses mapped to
virtual IP addresses
Optional.
When VRRP is operating in load balancing mode,
this configuration is not effective.
Creating a VRRP group and configuring virtual IP
address
Required.
Configuring router priority, preemptive mode and
tracking function
Optional.
Configuring VF tracking
Optional.
The VF tracking function is effective only when VRRP
is operating in load balancing mode.
Configuring VRRP packet attributes
Optional.
Enabling the trap function for VRRP
Optional.
Configuring a VRRP operation mode
VRRP can operate in either of the following modes:
•
Standard
protocol
mode
—When VRRP is operating in this mode, only the master in a VRRP group
is responsible for forwarding packets.
•
Load
balancing
mode
—When VRRP is operating in this mode, all the routers (master and backups)
that have the AVF in a VRRP group can forward packets, thus implementing load balancing.
After the VRRP operation mode is specified on a router, all VRRP groups on the router operate in the
specified operation mode.
To configure a VRRP operation mode:
Step
Command
Remarks
1.
Enter system view.
system-view
N/A
2.
Configure a VRRP
operation mode.
Configure VRRP to operate in
standard protocol mode:
undo vrrp mode
Configure VRRP to operate in load
balancing mode:
vrrp mode load-balance
Use either command.
By default, VRRP operates in standard
protocol mode.
Specifying the type of MAC addresses mapped to virtual IP
addresses
After you specify the type of MAC addresses mapped to the virtual IP addresses of VRRP groups and
create a VRRP group, the master in the VRRP group uses the specified type of MAC address as the source
MAC address for sending packets and uses the specified type of MAC address to answer ARP requests
