parameters for all prefixes. If a prefix has been configured with lifetime parameter values, the default
values cannot be applied using the ipv6 nd prefix default no-autoconfig command.
ipv6 neighbor
Configure a static entry in the IPv6 neighbor discovery.
Z9500
Syntax
ipv6 neighbor {ipv6-address} {interface interface} {hardware_address}
To remove a static IPv6 entry from the IPv6 neighbor discovery, use the no ipv6 neighbor {ipv6-
address} {interface interface} command.
Parameters
ipv6-address Enter the IPv6 address of the neighbor in the x:x:x:x::x format.
NOTE: The :: notation specifies successive hexadecimal fields of zero.
interface
interface
Enter the keyword interface then the interface type and slot/port or number
information:
● For a Port Channel interface, enter the keywords port-channel then a
number.
● For a 10-Gigabit Ethernet interface, enter the keyword
TenGigabitEthernet then the slot/port information.
● For a 40-Gigabit Ethernet interface, enter the keyword fortyGigE then the
slot/port information.
hardware_addres
s
Enter a 48-bit hardware MAC address in nn:nn:nn:nn:nn:nn format.
Defaults none

Usage
Information
Neighbor Discovery Protocol for IPv6 is defined in RFC 2461 as part of the Stateless Address
Autoconfiguration protocol. It replaces the Address Resolution Protocol used with IPv4. It defines
mechanisms for solving problems, such as:
● Router discovery: Hosts can locate routers residing on a link.
● Prefix discovery: Hosts can discover address prefixes for the link.
● Parameter discovery
● Address autoconfiguration — configuration of addresses for an interface
● Address resolution — mapping from IP address to link-layer address
● Next-hop determination
● Neighbor Unreachability Detection (NUD): Determine that a neighbor is no longer reachable on the
link.
