Displaying IPv6 neighbor information
You can display the IPv6 neighbor table, which contains a n entry for each I Pv6 neighbor wit h which
the router exchanges IPv6 packets.
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>
[<stack-unit>/<slot>/<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. Specify the Ethernet port in the
<stack-unit>/<slot>/<port> 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.
