Linksys
Only one link local address is supported If a link local address exists on the
interface, this entry replaces the address in the configuration
•
Global—An IPv6 address that is a global Unicast IPV6 type that is
visible and reachable from other networks
•
Point-to-Point—A Point-to-point tunnel
•
Metric—Value used for comparing this route to other routes with the same
destination in the IPv6 router table All default routes have the same value
•
Lifetime—Time period during which the packet can be sent, and resent,
before being deleted
•
Route Type—How the destination is attached, and the method used to
obtain the entry The following values are:
•
Local—A directly-connected network whose prefix is derived from a
manuallyconfigured device’s IPv6 address
•
Dynamic—The destination is an indirectly-attached (remote) IPv6
subnet address The entry was obtained dynamically via the ND or
ICMP protocol
IPv6 Neighbors
The IPv6 Neighbors page enables configuring and viewing the list of IPv6
neighbors on the IPv6 interface The IPv6 Neighbor Table (also known as IPv6
Neighbor Discovery Cache) displays the MAC addresses of the IPv6 neighbors
that are in the same IPv6 subnet as the device This is the IPv6 equivalent
of the IPv4 ARP Table When the device needs to communicate with its
neighbors, the device uses the IPv6 Neighbor Table to determine the MAC
addresses based on their IPv6 addresses
This page displays the neighbors that were automatically detected Each entry
displays to which interface the neighbor is connected, the neighbor’s IPv6
and MAC addresses, the entry type), and the state of the neighbor
To define IPv6 neighbors:
STEP 1 Click Configuration > IP Interface > IPv6 > IPv6 Neighbors
The following fields are displayed for the neighboring interfaces:
•
IPv6 Interface—Neighboring IPv6 interface type
•
IPv6 Address—IPv6 address of a neighbor
•
MAC Address—MAC address mapped to the specified IPv6 address
•
Type—Neighbor discovery cache information entry type
•
State—Specifies the IPv6 neighbor status The values are:
•
Incomplete—Address resolution is working The neighbor has not
yet responded
•
Reachable—Neighbor is known to be reachable
•
Stale—Previously-known neighbor is unreachable No action is taken
to verify its reachability until traffic must be sent
•
Delay—Previously-known neighbor is unreachable The interface
is in Delay state for a predefined Delay Time If no reachability
confirmation is received, the state changes to Probe
•
Probe—Neighbor is no longer known to be reachable, and Unicast
Neighbor Solicitation probes are being sent to verify the reachability
