152 Configuring System Information
Viewing the IPv6 Routes Table
The IPv6 Routes Table stores information about IPv6 destination prefixes and how they are reached,
either directly or indirectly. The routing table is used to determine the next-hop address and the interface
used for forwarding.
Each dynamic entry also has an associated invalidation timer value (extracted from Router
Advertisements) used to delete entries that are no longer advertised.
To open the IPv6 Routes Table page, click System→ IP Addressing→ IPv6 Routes Table in the tree view.

•
IPv6 Address
— Defines the destination IPv6 address.
•
Prefix Length
— Specifies the length of the IPv6 prefix. The Prefix field is applicable only when the
IPv6 Static IP address is defined as a Global IPv6 address. The range is 5 - 128.
•
Interface
— Displays the interface that is used to forward the packet. Interface refers to any Port,
LAGor VLAN.
•
Next
Hop — Defines the address to which the packet is forwarded on the route to the Destination address
(typically the address of a neighboring router). This can be either a Link Local or Global IPv6 address.
•
Metric
— Indicates the value used for comparing this route to other routes with the same destination in
the IPv6 route table. This is an administrative distance with the range of 0-255. The default value is1.
•Life-Time
— Indicates the life-time of the route.
•
Route
Typ e
— Displays whether the destination is directly attached and the means by which the entry
was learned. The following values are:
–
Local
— Indicates a directly connected route entry.
–
Static
— Indicates the route is learned through the ND process. The entry is automatically
converted to a static entry.
–
ICMP
— Indicates the route is learned through ICMP messages.
–
ND
— Indicates the route is learned through RA messages.
