reset ipv6 neighbors

Function

The reset ipv6 neighbors command clears dynamic IPv6 ND entries.

reset ipv6 neighbors { dynamic | { interface-name | interface-type interface-number } }

reset ipv6 neighbors vid vlan-id [ interface-name | interface-type interface-number ]

reset ipv6 neighbors dynamic { interface-name | interface-type interface-number } ipv6-address

Parameter	Description	Value
dynamic	Clears dynamic ND entries on all interfaces.	-
interface-name	Clears all dynamic ND entries on a specified interface.	-
interface-type interface-number	Clears dynamic ND entries on a specified interface.	-
vid vlan-id	Clears dynamic ND entries of a specified VLAN ID.	The value is an integer ranging from 1 to 4094.
ipv6-address	Clears dynamic ND entries with a specified IPv6 address on a specified interface.	The address is a 32-bit hexadecimal number, in the format of X:X:X:X:X:X:X:X.
