204 IP Addressing
– DAD Status —New addresses remain in a Tentative status while
duplicate address detection is performed. After it is performed
successfully, the DAD status is Active.
2 Enter the following fields to modify these parameters on a currently-
defined IPv6 interface:
–
Interface — Select a non-tunnel IPv6 interface to be configured.
–
Removed —Select to disable IPv6 support on this interface.
–
Duplicate Address Detection Attempts — Number of consecutive
neighbor solicitation messages that are sent on an interface while
Duplicate Address Detection (DAD) is performed on Unicast IPv6
addresses on this interface. New addresses remain in a tentative state
while duplicate address detection is performed. A field value of 0,
disables duplicate address detection processing on the specified
interface. A field value of 1, indicates a single transmission without
follow up transmissions.
NOTE: A field value of 0, disables duplicate address detection processing on the
specified interface. A field value of 1, indicates a single transmission without follow
up transmissions.
– Autoconfiguration — Enable/disable stateless auto configuration of
IPv6 address assignment. When enabled, the router solicitation ND
procedure is initiated. This discovers a router in order to assign an IP
address to the interface, based on prefixes received with RA messages.
When auto configuration is disabled, no automatic assignment of
IPv6 global Unicast addresses is performed, and existing,
automatically-assigned IPv6 global Unicast addresses are removed
from the interface.
–
Send ICMP Unreachable — Enable/disable transmission of ICMPv6
address Unreachable messages. When enabled, unreachable messages
are generated for any packet arriving on the interface with unassigned
TCP/UDP port.
–
IPv6 Redirects (for R1-2210)— Enable the sending of ICMP IPv6
redirect messages to re-send a packet through the same interface on
which the packet was received.
3 To configure the interface as a DHCPv6 client, meaning to enable the
interface to receive information from the DHCPv6 server, such as: SNTP
configuration and DNS information, enter the DHCPv6 Client fields:
