func ParseStaticLinkLocalRouteKey

func ParseStaticLinkLocalRouteKey(key string) (dstNetAddr *net.IPNet, outgoingInterface string, isRouteKey bool)

ParseStaticLinkLocalRouteKey parses route attributes from a key derived from link-local route.

func RouteKey

func RouteKey(dstNetwork, outgoingInterface string) string

RouteKey returns the key used in ETCD to store configuration of a particular Linux route.

func RouteKeyFromTemplate

func RouteKeyFromTemplate(template, dstAddr, outgoingInterface string) string

RouteKeyFromTemplate fills key template with route attributes.

func StaticLinkLocalRouteKey

func StaticLinkLocalRouteKey(dstAddr, outgoingInterface string) string

StaticLinkLocalRouteKey returns a derived key used to represent link-local route.

func StaticLinkLocalRoutePrefix

func StaticLinkLocalRoutePrefix(outgoingInterface string) string

StaticLinkLocalRoutePrefix returns longest-common prefix of keys representing link-local routes that have the given outgoing Linux interface.
