RouterOS has stateless IPv6 address autoconfiguration router-side support using Router Advertisement Daemon (RADVD). Prefixes of all addresses with 64 bit netmask are advertised by default.
General configuration
Sub-menu:/ipv6 nd
The menu contains one or more interface definitions on which router advertisement (RA) will be sent.
Each entry describes the information which is included in the RA of a specific interface.
Properties
Property
Description
advertise-dns (yes | no; Default: no)
advertise-mac-address (yes | no; Default: yes)
comment (string; Default: )
Descriptive name of an item
disabled (yes | no; Default: no)
Whether item is disabled or not. By default entry is enabled.
mtu (unspecified | integer[0..4294967295]; Default: unspecified)
The MTU option is used in router advertisement messages to insure that all nodes on a link use the same MTU value in those cases where the link MTU is not well known.
unspecified - do not send MTU option.
other-configuration (yes | no; Default: no)
ra-delay (time; Default: 3s)
The minimum time allowed between sending multicast router advertisements from the interface.
The time that a node assumes a neighbor is reachable after having received a reachability confirmation. Used by the Neighbor Unreachability Detection algorithm (see Section 7.3 of RFC 2461)
The time between retransmitted Neighbor Solicitation messages. Used by address resolution and the Neighbor Unreachability Detection algorithm (see Sections 7.2 and 7.3 of RFC 2461)

Properties

Description
6to4-interface (none | string; Default: )
If this option is specified, this prefix will be combined with the IPv4 address of interface name to produce a valid 6to4 prefix. The first 16 bits of this prefix will be replaced by 2002 and the next 32 bits of this prefix will be replaced by the IPv4 address assigned to interface name at configuration time. The remaining 80 bits of the prefix (including the SLA ID) will be advertised as specified in the configuration file.
autonomous (yes | no; Default: yes)
When set, indicates that this prefix can be used for autonomous address configuration as specified in RFC 2462.
comment (string; Default: )
Descriptive name of an item
disabled (yes | no; Default: no)
Whether item is disabled or not. By default entry is enabled.
on-link (yes | no; Default: yes)
When set, indicates that this prefix can be used for on-link determination. When not set the advertisement makes no statement about on-link or off-link properties of the prefix. For instance, the prefix might be used for address configuration with some of the addresses belonging to the prefix being on-link and others being off-link.
preferred-lifetime (infinity | time; Default: 1w)
The length of time (relative to the time the packet is sent) that addresses generated from the prefix via stateless address autoconfiguration remain preferred.
prefix (ipv6 prefix; Default: ::/64)
Prefix from which stateless address autoconfiguration generates the valid address.
valid-lifetime (infinity | time; Default: 4w2d)
The length of time (relative to the time the packet is sent) that the prefix is valid for the purpose of on-link determination. The valid lifetime is also used by RFC 2462.
