Viewing the NDP Table
Neighbor Discovery Protocol (NDP) is used with IPv6 to discover other nodes, determine the link layer
addresses of other nodes, find available routers, and maintain reachability information about the paths
to other active neighbor nodes.
NDP functionality includes:
• Router discovery
• Autoconfiguration of addresses (stateless address autoconfiguration [SLAAC])
• IPv6 address resolution (replaces Address Resolution Protocol [ARP])
• Neighbor reachability (neighbor unreachability detection [NUD])
• Duplicate address detection (DAD)
• Redirection
