IPv6 Router Advertisement on RV180 and RV180W

Objectives

IPv6 Router Advertisement Daemon (RADVD) broadcasts auto-configuration parameters and responds to Router Solicitations from clients that are trying to configure. The client is able to determine the default router, and other configuration information via Router Advertisements. These Router Advertisements tell a client whether to assign itself an IP address or obtain one from a DHCPv6 server.

This document explains how to configure Router Advertisement on the RV180 and RV180W.

Note: To Enable Router Advertisements IP Mode has to be configured first.

Applicable Devices

• RV180
