interfaces dataplane <interface> vrrp vrrp-group <group-id> fast-advertise-interval <interval>

Sets the advertisement interval for a VRRP version 3 group on an interface.

set interfaces dataplane interface vrrp vrrp-group group-id fast-advertise-interval interval
delete interfaces dataplane interface vrrp vrrp-group group-id fast-advertise-interval
show interfaces interface vrrp vrrp-group group-id advertise-interval

The master router sends advertisement packets in VRRP version 3 at intervals of 1000 ms (1 second).

interface
The type keyword and identifier of an interface data plane. For detailed keywords and arguments that can be specified as interfaces, refer to Supported Dataplane Interfaces.
group-id
The identifier of a VRRP group to which the interface belongs. The identifier ranges from 1 through 255.
interval
The interval between advertisement packets in VRRP version 3. All interfaces in a given VRRP group must use the same advertisement interval. The interval ranges from 10 through 40950 milliseconds. The default interval is 1000 milliseconds.

The VRRPv3 protocol operates in centiseconds and the millisecond value entered with the command is rounded up to the nearest 10 centiseconds for the protocol.

Configuration mode


interfaces dataplane interface {
    vrrp {
        vrrp-group group-id {
            fast-advertise-interval interval
        }
    }
}

Use this command to set the advertisement interval for a VRRP version 3 group on an interface.

Use the set form of the command to set the advertisement interval for a VRRP version 3 group on an interface.

Use the delete form of the command to restore the default advertisement interval of 1000 ms (1 second) for a VRRP version 3 group on an interface, which means that the master router sends advertisement packets ranging from 10 to 40950 milliseconds.

Use the show form of the command to display the advertisement interval for a VRRP version 3 group on an interface.

While it is possible to configure a value as low as 10ms, pay attention to the capability of the network and hardware the hello packets are running on. If values are too low, then the network may become unstable. Values of hundreds of milliseconds tend to work in most environments.
