Unified Services Router
accept such details. Router Advertisement is required in an IPv6 network is required for stateless
auto configuration of the IPv6 LAN. By configuring the Router Advertisement Daemon on this
router, the DSR will listen on the LAN for router solicitations and respond to these LAN hosts with
router advisements.
RADVD
Advanced > IPv6 > IPv6 LAN > Router Advertisement
To support stateless IPv6 auto configuration on the LAN, set the RADVD status to Enable. The
following settings are used to configure RADVD:

Advertise Mode: Select Unsolicited Multicast to send router advertisements (RA's) to all
interfaces in the multicast group. To restrict RA's to well-known IPv6 addresses on the LAN,
and thereby reduce overall network traffic, select Unicast only.

Advertise Interval: When advertisements are unsolicited multicast packets, this interval sets
the maximum time between advertisements from the interface. The actual duration between
advertisements is a random value between one third of this field and this field. The default
is 30 seconds.

RA Flags: The router advertisements (RA's) can be sent with one or both of these flags.
Chose Managed to use the administered /stateful protocol for address auto configuration. If
the Other flag is selected the host uses administered/stateful protocol for non-address auto
configuration.

Router Preference: this low/medium/high parameter determines the preference associated
with the RADVD process of the router. This is useful if there are other RADVD enabled
devices on the LAN as it helps avoid conflicts for IPv6 clients.

MTU: The router advertisement will set this maximum transmission unit (MTU) value for all
nodes in the LAN that are auto configured by the router. The default is 1500.

Router Lifetime: This value is present in RA's and indicates the usefulness of this router as
a default router for the interface. The default is 3600 seconds. Upon expiration of this value,
a new RADVD exchange must take place between the host and this router.
