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 [<ipv6-prefix> / | | nterface> [
| ]]
• The / 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
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.
I
MTU The setting of the maximum transmission unit (MTU) configured for the
IPv6 interface. The MTU is the maximum length an IPv6 packet can have
to be transmitted on the interface. If an IPv6 packet is longer than an
MTU, the host that originated the packet fragments the packet and
transmits its contents in multiple packets that are shorter than the
configured MTU.
ICMP The setting of the ICMP redirect parameter for the interface.
ND The setting of the various neighbor discovery parameters for the
interface.
