Layer 3 Management Configuration
2. IPv6 Neighbor Discovery Configuration
(a) Configure DAD Neighbor solicitation Message number
Command Explanation
Interface Configuration Mode
ipv6 nd dad attempts <value>
no ipv6 nd dad attempts Set the neighbor query message number sent in sequence
when the interface makes duplicate address detection. The
no command resumes default value (1).
(b) Configure Send Neighbor solicitation Message Interval
Command Explanation
Interface Configuration Mode
ipv6 nd ns-interval <seconds>
no ipv6 nd ns-interval Set the interval of the interface to send neighbor query mes-
sage. The NO command resumes default value (1 second).
(c) Configure static IPv6 neighbor Entries
Command Explanation
Interface Configuration Mode
ipv6 neighbor <ipv6-address> <hardware-
address>
interface <interface-type
interface-name>
Set static neighbor table entries, including neigh-
bor IPv6 address, MAC address and two-layer
port.
no ipv6 neighbor <ipv6-address> Delete neighbor table entries.
(d) Delete all entries in IPv6 neighbor table
Command Explanation
Admin Mode
clear ipv6 neighbors Clear all static neighbor table entries.
29.2.3 IPv6 Troubleshooting
• If the connected PC has not obtained IPv6 address, you should check the RA announcement
switch (the default is turned off)
29.3 Static Route
29.3.1 Introduction to Static Route
As mentioned earlier, the static route is the manually specified path to a network or a host. Static
route is simple and consistent, and can prevent illegal route modification, and is convenient for load
balance and route backup. However, it also has its own defects. Static route, as its name indicates,
is static, it won’t modify the route automatically on network failure, and manual configuration is
required on such occasions, therefore it is not suitable for mid and large-scale networks.
