Configuring Router Advertisement

The Router Advertisement Daemon (RADVD) on the Cisco RV120W listens for
router solicitations in the IPv6 LAN and responds with router advertisements as
required. This is stateless IPv6 auto configuration, and the Cisco RV120W
distributes IPv6 prefixes to all nodes on the network.
To configure the RADVD:
Choose Networking > IPv6 > Router Advertisement.
Under Router Advertisement Status, choose Enable.
Under Advertise Mode, choose one of the following:
• Unsolicited Multicast—Select this option to send router advertisements
(RAs) to all interfaces belonging to the multicast group.
• Unicast only—Select this option to restrict advertisements to well-known
IPv6 addresses only (router advertisements [RAs] are sent to the interface
belonging to the known address only).
If you chose Unsolicited Multicast in Step 3, enter the advertise interval. The
advertise interval is a random value between the Minimum Router Advertisement
Interval and Maximum Router Advertisement Interval. (MinRtrAdvInterval = 0.33 *
MaxRtrAdvInterval.) The default is 30 seconds.
Under RA Flags, check Managed to use the administered/stateful protocol for
address auto configuration. Check Other to use the administered/stateful protocol
of other, non-address information auto configuration.
Under router preference, choose Low, Medium, or High. The router preference
provides a preference metric for default routers. The low, medium and high values
are signaled in unused bits in Router Advertisement messages. This extension is
backward compatible, both for routers (setting the router preference value) and
hosts (interpreting the router preference value). These values are ignored by hosts
