Resolving IPv6 DAD
The link-local address is formed from an interface identifier based on the hardware address
which is supposed to be uniquely assigned. Once the DAD (Duplicate Address Detection)
detects the address duplication, the operation on the interface SHOULD be disabled.
At this moment, manual intervention is required to resolve the address duplication. For
example, check whether the loop occurs in the VLAN or there is indeed other device
occupying the same hardware address as the device in the VLAN.
After making sure the specific link-local address is unique on the IPv6 link in use, delete and
then add the specific IPv6 interface to restart the IPv6 operations on this interface.
IP Routes
Delete
Select this option to delete an existing IP route.
Network
The destination IP network or host address of this route. Valid format is dotted decimal
notation or a valid IPv6 notation. A default route can use the value
0.0.0.0
or IPv6
::
notation.
Mask Length
The destination IP network or host mask, in number of bits (
prefix length
). It defines how
much of a network address that must match, in order to qualify for this route. Valid values are
between 0 and 32 bits respectively 128 for IPv6 routes. Only a default route will have a mask
length of
0
(as it will match anything).
Gateway
The IP address of the IP gateway. Valid format is dotted decimal notation or a valid IPv6
notation. Gateway and Network must be of the same type.
Next Hop VLAN (Only for IPv6)
The VLAN ID (VID) of the specific IPv6 interface associated with the gateway.
The given VID ranges from 1 to 4095 and will be effective only when the corresponding IPv6
interface is valid.
If the IPv6 gateway address is link-local, it must specify the next hop VLAN for the gateway.
If the IPv6 gateway address is not link-local, system ignores the next hop VLAN for the
gateway.
