IPv6 Interface
– 1683 –
ipv6 neighbor
This command configures a static entry in the IPv6 neighbor discovery
cache. Use the no form to remove a static entry from the cache.

ipv6-address - The IPv6 address of a neighbor device that can be
reached through one of the network interfaces configured on this
switch. You can specify either a link-local or global unicast address
formatted according to RFC 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.
vlan-id - VLAN ID (Range: 1-4094)
hardware-address - The 48-bit MAC layer address for the neighbor
device. This address must be formatted as six hexadecimal pairs
separated by hyphens.

◆
Address Resolution Protocol (ARP) has been replaced in IPv6 with the
Neighbor Discovery Protocol (NDP). The ipv6 neighbor command is
similar to the mac-address-table static command that is implemented
using ARP.
◆
Static entries can only be configured on an IPv6-enabled interface.
◆
The switch does not determine whether a static entry is reachable
before placing it in the IPv6 neighbor discovery cache.
◆
If the specified entry was dynamically learned through the IPv6
neighbor discovery process, and already exists in the neighbor
discovery cache, it is converted to a static entry. Static entries in the
IPv6 neighbor discovery cache are not modified if subsequently
detected by the neighbor discovery process.
◆
Disabling IPv6 on an interface with the no ipv6 enable command (see
page 1670 ) deletes all dynamically learned entries in the IPv6 neighbor
discovery cache for that interface, but does not delete static entries.
