Managing the Neighbor Discovery Table

In IPv6 networking, network nodes use the Neighbor Discovery Protocol (NDP) to determine the Layer 2 MAC addresses for neighboring hosts and routers. The system uses NDP to maintain a cache of neighboring routers that are reachable and can forward packets on its behalf.

To manage the neighbor discovery table:

1. Select System > Network > Port > ND Cache. Port is the Internal Port, External Port, or Management Port tab.
2. Select Flush NDP Entries to delete all dynamically discovered entries.
