Static IPv6 routes are either:
• Directly-attached, meaning that the destination is directly-attached to an interface on
the device, so that the packet destination (which is the interface) is used as the next-
hop address.
• Recursive, where only the next-hop is specified, and the outgoing interface is derived
from the next-hop.
In the same manner, the MAC address of the next-hop devices (including directly-attached
end-systems) are automatically derived using Network Discovery. However, the user may
override and supplement this by adding manually entries to the Neighbors table.
IPv6 Global Configuration
To define IPv6 global parameters and DHCPv6 client settings:
Click IP Configuration > IPv6 Management and Interfaces > IPv6 Global Configuration.
Enter values for the following fields:
• IPv6 Routing—Select to enable IPv6 routing. If this is not enabled, the device acts as
a host (not a router) and can receive management packets, but cannot forward packets.
If routing is enabled, the device can forward the IPv6 packets.
Enabling IPv6 routing will remove any address previously assigned to the device
interface, via the auto-config operation, from an RA sent by a Router in the network.
• ICMPv6 Rate Limit Interval—Enter how often the ICMP error messages are
generated.
• ICMPv6 Rate Limit Bucket Size—Enter the maximum number of ICMP error
messages that can be sent by the device per interval.
• IPv6 Hop Limit—Enter the maximum number of intermediate routers on its way to the
final destination to which a packet can pass. Each time a packet is forwarded to another
router, the hop limit is reduced. When the hop limit becomes zero, the packet is
discarded. This prevents packets from being transferred endlessly.
• DHCPv6 Client Settings
- Unique Identifier (DUID) Format—This is the identifier of the DHCP client that is
used by the DHCP server to locate the client. It can be in one of the following
formats:
Link-Layer—(Default). If you select this option, the MAC address of the device is
used.
