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

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.
