2.1.2 Configuring IPv6 Router Advertisements

Router Advertisements are analogous to IPv4 DHCP assignments for LAN clients, in
that the router will assign an IP address and supporting network information to
devices that are configured to accept such detai ls. 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 thes e 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.


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 autoconfigured by the router.
The default is 1500.

Router Lifetime: This value is present in RA's and indicates the useful ness
of this router as a default router for the interface. The default is 3600
