A route defines the path between two network devices. Routing entries added by
the user are static, which are kept and used by the system until explicitly removed
by the user, and are not changed by routing protocols. When static routes must be
updated, this must be done explicitly by the user. It is the user's responsibility to
prevent routing loops in the network.
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

STEP 2
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.
•
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.
