IPv6 Interface
– 778 –
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.
Syntax
ipv6 neighbor ipv6-address vlan vlan-id hardware-address
no ipv6 mtu
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.
Default Setting
None

Command Usage
◆
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 760 ) deletes all dynamically learned entries in the IPv6 neighbor
discovery cache for that interface, but does not delete static entries.
