-

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.
•Router—Specifies whether the neighbor is a router (Yes or No).
STEP 3 To add a neighbor to the table, click Add.
STEP 4 Enter values for the following fields:

•IPv6 Address—Enter the IPv6 network address assigned to the interface.
The address must be a valid IPv6 address.
•MAC Address—Enter the MAC address mapped to the specified IPv6
address.
STEP 5 Click Apply. The Running Configuration file is updated.
STEP 6 To change the type of an IP address from Dynamic to Static, select the address,

Viewing IPv6 Route Tables
The IPv6 Forwarding Table contains the various routes that have been configured.
One of these routes is a default route (IPv6 address:0) that uses the default router
selected from the IPv6 Default Router List to send packets to destination devices
that are not in the same IPv6 subnet as the device. In addition to the default route,
the table also contains dynamic routes that are I CMP redirect ro utes received f rom
IPv6 routers by using ICMP redirect messages. This could happen when the
default router the device uses is not the router for traffic to which the IPv6 subnets
that the device wants to communicate.
