Functions

func CheckVxlanDevice

func CheckVxlanDevice(ctx context.Context, expected *netlink.Vxlan)

CheckVxlanDevice checks if the vxlan device is correctly configured.

func GenerateVxlanMac

func GenerateVxlanMac(nodename string) (net.HardwareAddr, error)

GenerateVxlanMac generate VXLAN MAC address.

Types

type Neighbor

type Neighbor struct {
	MAC net.HardwareAddr
	IP  net.IP
}

Neighbor struct that holds information for an fdb entry.

type VxlanDevice

type VxlanDevice struct {
	Link *netlink.Vxlan
}

VxlanDevice struct that holds a vxlan link.

func NewVxlanDevice

func NewVxlanDevice(devAttrs *VxlanDeviceAttrs) (*VxlanDevice, error)

NewVxlanDevice takes as argument a struct of type VxlanDeviceAttrs and returns a VxlanDevice or error.

func (*VxlanDevice) AddFDB

func (vxlan *VxlanDevice) AddFDB(n Neighbor) (bool, error)

AddFDB adds a fdb entry for the given neighbor into the current vxlan device. It returns an error if something goes wrong, and bool value set to true if it added the entry, otherwise is set to false.

func (*VxlanDevice) ConfigureIPAddress

func (vxlan *VxlanDevice) ConfigureIPAddress(ipAddr string) error

ConfigureIPAddress configures the IP address of the vxlan interface. The IP address has to be in CIDR notation.

func (*VxlanDevice) DelFDB

func (vxlan *VxlanDevice) DelFDB(n Neighbor) (bool, error)

DelFDB deletes a fdb entry for the given neighbor from the current vxlan device. It return an error if something goes wrong, and bool value to sai if it deleted the entry, if the entry does not exist the bool value is set to false.

type VxlanDeviceAttrs

type VxlanDeviceAttrs struct {
	Vni      int
	Name     string
	VtepPort int
	VtepAddr net.IP
	MTU      int
	MAC      net.HardwareAddr
}

VxlanDeviceAttrs configuration for a new vxlan device.
