tunnel endpoint for the VxLAN

type VxlanConfig

type VxlanConfig struct {
	VNI    uint32
	VlanId uint16 // used to tag inner ethernet frame when egressing
	Group  net.IP // multicast group IP
	MTU    uint32 // MTU size for each VTEP
}

bridge for the VNI

type VxlanDbEntry

type VxlanDbEntry struct {
	VNI    uint32
	VlanId uint16 // used to tag inner ethernet frame when egressing
	Group  net.IP // multicast group IP
	MTU    uint32 // MTU size for each VTEP
	Brg    *netlink.Bridge
	Links  []*netlink.Link
}

type VxlanLinux

type VxlanLinux struct {
	// contains filtered or unexported fields
}

func NewVxlanLinux

func NewVxlanLinux(logger *logging.Writer) *VxlanLinux

func (*VxlanLinux) CreateVtep

func (v *VxlanLinux) CreateVtep(c *VtepConfig)

func (*VxlanLinux) CreateVxLAN

func (v *VxlanLinux) CreateVxLAN(c *VxlanConfig)

createVxLAN is the equivalent to creating a bridge in the linux The VNI is actually associated with the VTEP so lets just create a bridge if necessary

func (*VxlanLinux) DeleteVtep

func (v *VxlanLinux) DeleteVtep(c *VtepConfig)

func (*VxlanLinux) DeleteVxLAN

func (v *VxlanLinux) DeleteVxLAN(c *VxlanConfig)

func (*VxlanLinux) LearnFdbVtep

func (v *VxlanLinux) LearnFdbVtep(mac string, vtepname string, ifindex int32)

type VxlanMacDbEntry

type VxlanMacDbEntry struct {
	// contains filtered or unexported fields
}
