type MainTableOwnershipPolicy

type MainTableOwnershipPolicy struct {
	WorkloadInterfacePrefixes     []string
	RemoveNonCalicoWorkloadRoutes bool

	// CalicoSpecialInterfaces is a list of interfaces that Calico uses for
	// tunnels and special purposes.
	CalicoSpecialInterfaces []string

	// AllRouteProtocols is a list of protocols that Calico uses,
	// but may be used by other software too.

}

MainTableOwnershipPolicy is the MainTableOwnershipPolicy for the main routing table. It needs to discriminate between our routes and routes from other applications. It does that based on various heuristics that try to capture Felix's current and historic behaviour. It would have been a lot cleaner if we'd picked a "protocol" value for all our routes on day one and stuck to it!

func NewMainTable

func NewMainTable(
	vxlanIfaceName string,
	deviceRouteProto netlink.RouteProtocol,
	workloadIfacePrefixes []string,
	removeExternalRoutes bool,
) *MainTableOwnershipPolicy

NewMainTable calculates the ownership policy for the main routing table, given Felix's configuration.
