Specifying an IPv4 VRRP operating mode
A VRRP group can operate in either of the following modes:
•
Standard mode—Only the master can forward packets.
•
Load balancing mode—All members that have an AVF can forward packets.
After an IPv4 VRRP operating mode is configured on a router, all IPv4 VRRP groups on the router operate
in the specified operating mode.
To specify an IPv4 VRRP operating mode:
Step Command
Remarks
1.
Enter system view.
system-view
N/A
2.
Specify an IPv4 VRRP
operating mode.
•
Specify the standard mode:
undo vrrp mode
•
Specify the load balancing
mode:
vrrp mode load-balance
Use one of the commands.
By default, VRRP operates in
standard mode.
Specifying the IPv4 VRRP version
The VRRP version on all routers in an IPv4 VRRP group must be the same.
To specify the version of IPv4 VRRP:
Step Command
Remarks
1.
Enter system view.
system-view
N/A
2.
Enter interface view.
interface interface-type interface-number N/A
3.
Specify the version of
VRRP.
vrrp version version-number
By default, VRRPv3 is used.
Creating a VRRP group and assigning a virtual IP address
A VRRP group can operate correctly after you create it and assign at least one virtual IP address to it. You
can configure multiple virtual IP addresses for the VRRP group on an interface that connects to multiple
subnets for router backup on different subnets.
Configuration guidelines
•
The maximum number of VRRP groups that you can create on an interface and the maximum
number of virtual IP addresses that you can assign to a VRRP group depend on the device model.
•
In VRRP load balancing mode, the device supports a maximum of MaxVRNum/N VRRP groups.
MaxVRNum refers to the maximum number of VRRP groups supported by the device in VRRP
standard mode, and N refers to the number of devices in the VRRP group.
•
When VRRP is operating in standard mode, the virtual IP address of a VRRP group can be either an
unused IP address on the subnet where the VRRP group resides or the IP address of an interface on
a router in the VRRP group.
