PLANET XGS3-24040 - Manual (Page 256)

17-14
Usage Guide:
If router A, router B, and node C are on the same network link, and router A forwards IPv6 packets
from node C to router B, expecting router B to continue the forwarding, then router A will send an
IPv6 ICMPv6 redirect message to node C-source of the packet, notifying it that the best next hop of
this destination address is router B. By doing so, the forwarding overhead of router A will be
decreased, so is the network transmission delay of node C.
Examples:
Enable IPv6 router redirect function.
Switch(config)# ipv6 redirect
17.2.13 ipv6 nd dad attempts
Command:
ipv6 nd dad attempts <value>
no ipv6 nd dad attempts
Function:

Detection, and the value of <value> must be in 0-10, NO command restores to default value 1.
Command Mode:
Interface Configuration Mode
Default:
The default request message number is 1.
Usage Guide:
When configuring an IPv6 address, it is required to process IPv6 Duplicate Address Detection, this
command is used to configure the ND message number of Duplicate Address Detection to be sent,
value being 0 means no Duplicate Address Detection is executed.
Example:
The Neighbor Solicitation Message number sent in succession by interface when setting Duplicate
Address Detection is 3.
Switch(Config-if-Vlan1)# ipv6 nd dad attempts 3
17.2.14 ipv6 nd ns-interval
