pub enum DropReason {

    ForwardLinkLocal,
    ForwardingDisabledInboundIface,
    MulticastNoInterest,

Expand description

The reason a received IP packet is dropped.

Variants§

§

Tentative

Remote packet destined to tentative address.

§

UnspecifiedDestination

Remote packet destined to the unspecified address.

§

ForwardUnspecifiedSource

Cannot forward a packet with unspecified source address.

§

ForwardLinkLocal

Cannot forward a packet with link-local source or destination address.

§

ForwardingDisabledInboundIface

Packet should be forwarded but packet’s inbound interface has forwarding disabled.

§

MulticastNoInterest

Remote packet destined to a multicast address that could not be:

  • delivered locally (because we are not a member of the multicast group), or
  • forwarded (either because multicast forwarding is disabled, or no applicable multicast route has been installed).
