Module ndp

Helpers for tests involving the Neighbor Discovery Protocol.

Constants

• MESSAGE_TTL
  As per RFC 4861 sections 4.1-4.5, NDP packets MUST have a hop limit of 255.

Functions

• assert_dad_failed
  Assert that the address state provider event stream yields an address removal error, indicating that DAD failed.
• assert_dad_success
  Assert that the address state provider event stream yields an address assignment event, implying that DAD succeeded.
• expect_dad_neighbor_solicitation
  Wait for and verify a NS message transmitted by netstack for DAD. Returns the bytes of the NS message.
• fail_dad_with_na
  Transmit a Neighbor Advertisement message simulating that a node owns constants::ipv6::LINK_LOCAL_ADDR.
• fail_dad_with_ns
  Transmit a Neighbor Solicitation message simulating that a node is performing DAD for constants::ipv6::LINK_LOCAL_ADDR.
• send_ra
  Send Router Advertisement NDP message.
• send_ra_with_router_lifetime
  Send Router Advertisement NDP message with router lifetime.
• wait_for_router_solicitation
  Wait for a router solicitation message.
• write_message
  Write an NDP message to the provided fake endpoint.

Type Aliases

• DadState
  A result type that can be used to evaluate the outcome of Duplicate Address Detection (DAD).
