IPv6 Configuration Task List 535
Configure the attempts to send an ns message for duplicate address
detection
The device sends a neighbor solicitation (NS) message for duplicate address
detection. If the device does not receive a response within a specified time (set by
the ipv6 nd ns retrans-timer command), the device continues to send an NS
message. If the device still does not receive a response after the number of
attempts to send an NS message reaches the maximum, the device judges the
acquired address is available.
Configure the hop limit
When sending an IPv6 packet, the device will use this argument to fill in the Hop
Limit field in the IPv6 packet header. Upon receipt of the packet, the receiver will
also respond a packet carrying with this argument in the Hop Limit field.
Configure the NS Interval
After a device sends an NS message, if it does not receive a response within a
specific period, the device will send another NS message. You can configure the
interval for sending NS messages.
