ipv6 nd dad attempts 60

•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 60-2)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 Address	Age	Link-layer Addr	State	Vlan
2009:DB9:2229::80	956	12-34-11-11-43-21	STALE	1
2009:DB9:2229::81	Permanent	30-65-14-01-11-86	REACH	1
FE80::1034:11FF:FE11:4321	961	12-34-11-11-43-21	STALE	1

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)

Default Setting

1

Command Mode

Interface Configuration (VLAN)

Command Usage

•Configuring a value of 0 disables duplicate address detection.

•Duplicate address detection determines if a new unicast IPv6 address already exists on the network before it is assigned to an interface.

•Duplicate address detection is stopped on any interface that has been suspended (see the vlan command on page 52-6). While an interface is suspended, all unicast IPv6 addresses assigned to that interface are placed
