IPv6 Neighbor Discovery (ND) protocol is configured.

FlagNameDescription

*defaultdefault
ArgumentTypeDescription
interfaceiface_enum { all:0 }

Interface on which to run neighbor discovery. -all - run ND on all running interfaces.

ra-intervalsuper { time [3 .. 1250] , -time [4 .. 1800] }Minimum and maximum interval allowed between unsolicited multicast router advertisements from the interface.
ra-delaytimeMinimum time between multicast router advertisements from the interface.
mtualt { enum (unspecified) { unspecified:0 } , num }

The MTU option in router advertisements ensures that all nodes on a link use the same MTU value when the link MTU is not well known.

  • unspecified - do not send the MTU option.
reachable-timealt { enum (unspecified) { unspecified:0 } , time [ .. 3600] }Time that RouterOS assumes a neighbor is reachable after receiving a reachability confirmation. Used by Neighbor Unreachability Detection (see Section 7.3 of RFC 4861).
retransmit-intervalalt { enum (unspecified) { unspecified:0 } , time }Time between retransmitted Neighbor Solicitation messages. Used by address resolution and Neighbor Unreachability Detection (see Sections 7.2 and 7.3 of RFC 4861).
ra-lifetimealt { enum (none) { none:0 } , time [ .. 9000] }Set the RA lifetime. A lifetime of 0 indicates that this router is not a default router. See Section 6.2.3 of RFC 4861.
ra-preferenceenum (low | medium | high)Specify the router preference communicated to IPv6 hosts in router advertisements. The preference value helps hosts select a default router to reach a remote destination.
hop-limitalt { enum (unspecified) { unspecified:0 } , num [ .. 255] }Default value placed in the Hop Count field of the IPv6 header for outgoing unicast packets.
boolWhen set, include the outgoing interface's link-layer address in router advertisements.
enum (no | yes | self)

Redistribute DNS server information using RADVD.

  • yes - advertise DNS servers installed on the router.
  • self - advertise the interface link-local address as the DNS service provider.
managed-address-configurationboolIndicates whether hosts should use stateful autoconfiguration (DHCPv6) to obtain addresses. See RFC 3315.
other-configurationboolIndicates whether hosts should use stateful autoconfiguration to obtain additional information, excluding addresses. See RFC 3315.
dnsmulti { address (flags=6) }Specify one or more IPv6 addresses that hosts receive for DNS server configuration.
pref64object { ip6Prefix }Specify one or more IPv6 prefixes within /32, /40, /48, /56, /64, or /96 subnets that hosts receive as NAT64 prefixes.
