RouterOS manual

Neighbor



ipv6/neighbor

Type: Directory

List of all discovered nodes by the IPv6 Neighbor Discovery protocol, or nodes added manually by configuration.

The default maximum number of neighbor entries depends on installed RAM. Adjust it with /ipv6/settings/set max-neighbor-entries=x. See IPv6 Settings for details.

<ArgTableRow arg="X" typ="disabled">disabled</ArgTableRow> <ArgTableRow arg="D" typ="dynamic">dynamic</ArgTableRow> <ArgTableRow arg="R" typ="router">router</ArgTableRow>

<ArgTableRow arg="address" typ="ip6Addr">IPv6 address of the neighbor.</ArgTableRow> <ArgTableRow arg="interface" typ="iface_enum">Interface name to which this neighbor is attached.</ArgTableRow> <ArgTableRow arg="mac-address" typ="macAddr">MAC address of the device to add.</ArgTableRow>

Status of the cached entry:

  • noarp - the neighbor entry is valid. RouterOS does not validate this entry, but it can be removed when its lifetime expires.
  • incomplete - address resolution is in progress and the neighbor's link-layer address is not yet determined.
  • reachable - the neighbor was reachable recently (within tens of seconds).
  • stale - the neighbor is no longer known to be reachable. Will continue sending traffic to the neighbor before attempting reachability verification.
  • delay - the neighbor is no longer known to be reachable, and traffic has recently been sent to the neighbor. RouterOS delays probes briefly to allow the upper-layer protocol to confirm reachability.
  • probe - the neighbor is no longer known to be reachable and unicast Neighbor Solicitation probes are being sent to verify reachability.
  • failed - RouterOS could not resolve the neighbor's MAC address using the Neighbor Discovery protocol.
