Configuring Priority, Preemptive Mode And Interface Tracking For A Vrrp Group - H3C S9500 Series Operation Manual

Operation Manual – VRRP
H3C S9500 Series Routing Switches
Caution:
For S9500 series switches, the maximum number of VRRPv2 VRRP groups on an
interface is 16, the maximum number of virtual IP addresses in a VRRP group is 16
and the maximum number of VRRP groups on a switch is 96.
A VRRP group is removed after you remove all the virtual IP addresses in it. In
addition, configurations on that VRRP group no longer take effect.
Removal of the VRRP group on the IP address owner will cause IP address collision.
In such a case, it is recommended to modify the IP address of the interface on the IP
address owner to resolve the collision.
The virtual IP address of the VRRP group cannot be 0.0.0.0, 255.255.255.255,
loopback address, non A/B/C address and other illegal IP addresses such as
0.0.0.1.
Only when the configured virtual IP address and the interface IP address belong to
the same segment and are legal host addresses can the VRRP group operate
normally. If the configured virtual IP address and the interface IP address do not
belong to the same network segment, or the configured IP address is the network
address or network broadcast address of the network segment to which the
interface IP address belongs, the state of the VRRP group is always initialize,
though you can perform the configuration successfully, that is, VRRP does not take
effect in this case.
1.2.5 Configuring Priority, Preemptive Mode and Interface Tracking for a VRRP
Group
I. Configuration prerequisites
Before you configure these features, you should first create a VRRP group on the
interface and configure virtual IP address for it.
II. Configuration procedure
By configuring priority, preemption mode and interface tracking for a VRRP group, you
can decide which switch in the VRRP group serves as the Master.
