Viewing the NDP Table
Neighbor Discovery Protocol (NDP ) is used with IPv6 to discover othe r n od e s , 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
