IP Addressing 217
To add an IPv6 neighbor:
1
Click System > IPv6 Addressing > IPv6 Neighbors in the tree view to
display the
IPv6 Neighbors: Summary page.
The following fields are displayed for previously-defined neighbors:
–
Interface —Interface connected to the neighbor.
–
IPv6 Address —IPv6 address of the neighbor.
–
MAC Address —MAC address of the neighbor.
–
Ty p e —Neighbor discovery cache information entry type (static or
dynamic).
–
State (for R1-2210)—The possible states are:
•
Incomplete — An address resolution is in progress, and the link-
layer address of the neighbor has not yet been determined.
•
Reachable — The neighbor is known to have been reachable
recently (within tens of seconds).
•
State — The neighbor is no longer known to be reachable, but
until traffic is sent to the neighbor, no attempt is made to verify
its reachability.
•
Delay — The neighbor is no longer known to be reachable, and
traffic has recently been sent to the neighbor. Rather than probe
the neighbor immediately, however, there is a delay sending
probes for a short while, in order to give upper-layer protocols a
chance to provide reachability confirmation.
•
Probe — The neighbor is no longer known to be reachable, and
Unicast Neighbor Solicitation probes are being sent to verify
reachability.
–
Router —Whether the neighbor is a router (Yes or NA).
2 To clear the Neighbors table, select one of the following options:
–
None — Does not clear any entries.
–
Static Only — Clears the static entries.
–
Dynamic Only — Clears the dynamic entries.
–
All Dynamic and Static — Clears the static and dynamic address
entries.
