Types

type Layer2Information

type Layer2Information struct {
	VlanID int
	MTU    int
	VNI    int
	VRF    string

	AnycastMAC         *net.HardwareAddr
	AnycastGateways    []*netlink.Addr
	AdvertiseNeighbors bool
	NeighSuppression   *bool

	CreateMACVLANInterface bool
	// contains filtered or unexported fields
}

type NetlinkManager

type NetlinkManager struct {
}

func (*NetlinkManager) CleanupL2

func (n *NetlinkManager) CleanupL2(info Layer2Information) []error

func (*NetlinkManager) CleanupL3

func (n *NetlinkManager) CleanupL3(name string) []error

Cleanup will try to delete all interfaces associated with this VRF and return a list of errors (for logging) as a slice

func (*NetlinkManager) CreateL2

func (n *NetlinkManager) CreateL2(info Layer2Information) error

func (*NetlinkManager) CreateL3

func (n *NetlinkManager) CreateL3(info VRFInformation) error

Create will create a VRF and all interfaces neccessary to operate the EVPN and leaking

func (*NetlinkManager) GetBridgeId

func (n *NetlinkManager) GetBridgeId(info Layer2Information) (int, error)

func (*NetlinkManager) GetL3ByName

func (n *NetlinkManager) GetL3ByName(name string) (*VRFInformation, error)

func (*NetlinkManager) GetUnderlayIP

func (n *NetlinkManager) GetUnderlayIP() (net.IP, error)

func (*NetlinkManager) ListL2

func (n *NetlinkManager) ListL2() ([]Layer2Information, error)

func (*NetlinkManager) ListL3

func (n *NetlinkManager) ListL3() ([]VRFInformation, error)

func (*NetlinkManager) ParseIPAddresses

func (n *NetlinkManager) ParseIPAddresses(addresses []string) ([]*netlink.Addr, error)

func (*NetlinkManager) ReconcileL2

func (n *NetlinkManager) ReconcileL2(current Layer2Information, desired Layer2Information) error

func (*NetlinkManager) UpL3

func (n *NetlinkManager) UpL3(info VRFInformation) error

UpL3 will set all interfaces up. This is done after the FRR reload to not have a L2VNI for a short period of time

type VRFInformation

type VRFInformation struct {
	Name string
	VNI  int

	MarkForDelete bool
	// contains filtered or unexported fields
}
