Command Usage
• Address Resolution Protocol (ARP) has been replaced in IPv6 with the
Neighbor Discovery Protocol (NDP). The ipv6 neighbor command is similar
to the mac-address-table static command (page 31-1) that is implemented
using ARP.
• Static entries can only be configured on an IPv6-enabled interface.
• The router does not determine whether a static entry is reachable before
placing it in the IPv6 neighbor discovery cache.
• If the specified entry was dynamically learned through the IPv6 neighbor
discovery process, and already exists in the neighbor discovery cache, it is
converted to a static entry. Static entries in the IPv6 neighbor discovery cache
are not modified if subsequently detected by the neighbor discovery process.
• Disabling IPv6 on an interface with the no ipv6 enable command (see
page 41-7) deletes all dynamically learned entries in the IPv6 neighbor
discovery cache for that interface, but does not delete static entries.
Example
The following maps a static entry for global unicast address to a MAC address:
Console(config)#ipv6 neighbor 2009:DB9:2229::81 vlan 1 30-65-14-01-11-86
Console(config)#end
Console#show ipv6 neighbors

ipv6 nd dad attempts
This command configures the number of consecutive neighbor solicitation
messages sent on an interface during duplicate address detection. Use the no form
to restore the default setting.
Syntax
ipv6 nd dad attempts count
no ipv6 nd dad attempts
count - The number of neighbor solicitation messages sent to determine
whether or not a duplicate address exists on this interface. (Range: 0-600)
