reachability of a neighbor. Therefore, avoid using very s hort interv als for

normal IPv6 operations.

Example

The following sets the interval between sending neighbor solicitation messages to

30000 milliseconds:

Console(config)#interface vlan 1

Console(config-if)#ipv6 nd ns-interval 30000

Console(config-if)#end

Console#show ipv6 interface

Vlan 1 is up

IPv6 is enable.

Link-local address:

FE80::200:E8FF:FE90:0/64

Global unicast address(es):

2009:DB9:2229::79, subnet is 2009:DB9:2229:0::/64

Joined group address(es):

FF01::1/16

FF02::1/16

FF02::1:FF00:79/104

FF02::1:FF90:0/104

MTU is 1500 bytes.

ND DAD is enabled, number of DAD attempts: 5.

ND retransmit interval is 1000 milliseconds

ND router advertisements are sent every 200 seconds

show ipv6 neighbors

This command displays information in the IPv 6 neighbo r discov ery cache .

Syntax

show ipv6 neighbors [vlan vlan -id | ipv6-address]

• vlan-id - VLAN ID (Range: 1-4093)

• ipv6-address - The IPv6 addr ess of a neighbo r device. Yo u can specif y

either a link-local or global unicast address formatted according to RF C

2373 “IPv6 Addressing Architecture,” using 8 colon-separated 16-bit

hexadecimal values. One double colon may be used in the address to

indicate the appropriate number of zeros required to fill the undefined fields.

Default Setting

All IPv6 neighbor discovery cache entries are d isplayed.

Command Mode

Normal Exec - No command options are availa ble.
