ipv6 neighbor
Configure a static entry in the IPv6 neighbor discovery.
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 Fast Ethernet interface, enter the keyword fastEthernet then the
slot/port 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.

show ipv6 neighbors
Display IPv6 discovery information. Entering the command without options shows all the IPv6 neighbor addresses stored on the
control processor (CP).
Syntax
show ipv6 neighbors [vrf vrf-name] [ipv6-address| interface interface]
Parameters
vrf vrf-name (OPTIONAL) Enter the keyword vrf followed by the name of the VRF to display the
neighbors corresponding to that VRF.
NOTE: If you do not specify this option, neighbors corresponding to the
default VRF are displayed.
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.
