ZXR10 5900E Series Configuration Guide (IPv6)
Command
Function
ZXR10#
show nd6 cache
Shows the IPv6 neighbor cache
table. The display results show
not only the entries generated by
the ND protocol for the routes to
neighbors but also static neighbor
cache entries.
The following example shows the outputs of the command
show nd6 cache
. This command
can be run to check the static ND entries and the ND entries dynamically learned including
the MAC address, the entry status, the age of this status, and the corresponding interface
name:
ZXR10#show nd6 cache
Total Cache Number Is:5

The outputs of the command
show nd6 cache
are described as follows:
Command Output
Description
Address
Indicates the IP address.
link-Address
Indicates the link layer address.
age
Indicates the age of the entry in this status or other attributes.
infinity: Indicates that the corresponding interface address
is infinitely valid.
static: Indicates that the entry is a static entry infinitely valid.
status
Indicates the status of the ND entry. Incomplete: The
entry has been generated but the link layer address is not
determined because address resolution is under way.
Reachable: The known entry is recently reachable.
Stale: The known entry is recently unreachable. If
stale-switch function is configured, the neighbor reachability
is before the entity is deleted. Otherwise, the neighbor
reachability is not verified until there are communication
messages to the neighbor.
Delay: The known entry is recently unreachable and there are
communication messages to the neighbor. In this status, the
NS packet (also called the probe packet) will be delayed for a
period of time to provide the opportunity for the upper-layer
protocol to verify the reachability of the neighbor.
