Displaying global IPv6 information

Displaying IPv6 neighbor information
You can display the IPv6 neighbor table, which contains an entry for each IPv6 neighbor with which
the router exchanges IPv6 packets.
To display the IPv6 neighbor table, enter the following command at any CLI level.
Syntax: show ipv6 neighbor [/ | |
[// ] |]]
The / parameters restrict the display to the entries for the specified
IPv6 prefix. You must specify the parameter in hexadecimal using 16-bit values
between colons as documented in RFC 2373. You must specify the parameter as a
decimal value. A slash mark (/) must follow the parameter and precede the
parameter.
The 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 parameter restricts the display to the entries for the specified router interface. For
this parameter, you can specify the Ethernet or VE keywords. Specify the Ethernet port in the
// format. Stack-unit is 1. If you specify a VE interface, also specify the VE
number.
This display shows the following information.
I TABLE 31 IPv6 neighbor information fields
Field Description
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 static forward path to the neighbor is functioning
properly.
•
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.
