Displaying global IPv6 information
43
To display the IPv6 neighbor table, enter the following command at any CLI level.
Syntax: show ipv6 neighbor [< ipv6-prefix >/< prefix-length > | < ipv6-address > | < interface >
[< port > |< number >]]
The < ipv6-prefix >/< prefix-length > parameters restrict the display to the entries for the specified
IPv6 prefix. You must specify the < ipv6-prefix > parameter in hexadecimal using 16-bit values
between colons as documented in RFC 2373. You must specify the < prefix-length > parameter as a
decimal value. A slash mark (/) must follow the < ipv6-prefix > parameter and precede the
< prefix-length > parameter.
The < ipv6-address> parameter restricts the display to the entries for the specified IPv6 address.
You must specify this parameter in hexadecimal using 16-bit values between colons as
documented in RFC 2373.
The < interface > parameter restricts the display to the entries for the specified router interface. For
this parameter, you can specify the Ethernet or VE keywords. If you specify an Ethernet interface,
also specify the port number associated with the interface. If you specify a VE interface, also
specify the VE number.
This display shows the following information.

TABLE 177
IPv6 neighbor information fields
This field... Displays...
Total number of neighbor entries The total number of entries in the IPv6 neighbor table.
IPv6 Address The 128-bit IPv6 address of the neighbor.
Link-Layer Address The 48-bit interface ID of the neighbor.
State The current state of the neighbor. Possible states are as follows:
•
INCOMPLETE – Address resolution of the entry is being performed.
•
REACH – The forward path to the neighbor is functioning properly.
•
STALE – This entry has remained unused for the maximum interval.
While stale, no action takes place until a packet is sent.
•
DELAY – This entry has remained unused for the maximum interval,
and a packet was sent before another interval elapsed.
•
PROBE – Neighbor solicitation are transmitted until a reachability
confirmation is received.
Age The number of seconds the entry has remained unused. If this value
remains unused for the number of seconds specified by the ipv6 nd
reachable-time command (the default is 30 seconds), the entry is
removed from the table.
Port The port on which the entry was learned.
IsR Determines if the neighbor is a router or host.
0 – Indicates that the neighbor is a host.
1 – Indicates that the neighbor is a router.
