represented as 4 hexadecimal numbers)
- prefix_length—IPv6 prefix length—decimal number—
quantity of address high bits comprising the prefix
- eui-64—identifier, based on the interface MAC address,
recorded in 64 lower bits of IPv6 address
- anycast—identifies that the specified address is the anycast
address.
no ipv6 address
[ipv6_address/
prefix_length] [eui-64]
Remove IPv6 address from the interface.
By default, automatic
configuration is enabled,
addresses are not defined.
Enable automatic IPv6 address configuration for the interface.
Addresses are configured depending on prefixes, that were
received in Router Advertisement messages.
no ipv6 address autoconfig
Restore the default value.
ipv6 address ipv6_address/
prefix_length link-local
Default value for local
address: (FE80::EUI64)
Define local IPv6 interface address. High bits of the local IP
addresses in IPv6—FE80::
no ipv6 address
[ipv6_address/prefix-length
link-local]
Remove the local IPv6 address.
ipv6 nd dad attempts
attempts_number
Specify the quantity of demand messages, sent via the
interface to the device, when IPv6 address duplication
(collision) is detected.
Disable ICMPv6 'destination inaccessible' messages, when
sending packets to the specific interface.
Restore the default value.
Define MLD protocol version for the interface.
Restore the default value.
ipv6 mld join-group
ipv6_multicast_address
Define MLD messages for the specific group.
- ipv6_multicast_address—IPv6 address of a multicast group.
no ipv6 mld join-group
ipv6_multicast_address
Disable reporting and remove IP address from a multicast
group.

Show information on the neighbouring IPv6 devices, stored in
cache.
- static—show static records
- dynamic—show dynamic records
Clear cache, that contains the information on the
neighbouring devices operating via IPv6 protocol. Information
on static records will remain.
