REACH
Possible states:
INCMP (Incomplete)
—address resolution procedure is performed at the entry. It means that
neighbouring request has been sent to the multicast address, but the respective neighbouring
confirmation is not received yet.
REACH (Reachable)
—positive confirmation; means that the route to the neighbouring device works
correctly; received during the reachable time (ReachableTime, ms). While the neighbouring device is
accessible and the packet exchange goes without errors, no special actions are taken.
STALE
—positive confirmation; means that the route to the neighbouring device works correctly;
received after the reachable time period (ReachableTime, ms). While the neighbouring device is
accessible and the packet exchange goes without errors, no special actions are taken.
DELAY
—positive confirmation; means that the route to the neighbouring device works correctly;
received after the reachable time period (ReachableTime, ms) and the next request was sent during
attempt time interval (DELAY_FIRST_PROBE_TIME, seconds). If the positive reply is not received
during attempt time interval (DELAY_FIRST_PROBE_TIME, seconds), the route state to the
neighbouring device will be changed to PROBE.
PROBE
—neighbouring requests are sent periodically with the 'retranslation' interval (RetransTimer,
ms) until the positive confirmation is received.
5.14.2
IPv6 protocol tunnelling (ISATAP)
IPv6 traffic tunnelling function based on ISATAP (Intra-Site Automatic Tunnel Addressing Protocol)
allows to transfer IPv6 traffic via IPv4 addressing networks. Thus, nodes with IPv6 addressing, that support
ISATAP tunnelling, will be able to communicate by icapsulating traffic into packets with IPv4 header.
