Opening excerpt (first ~120 words) tap to expand
radvd: IPv6 Router Advertisement Daemon The router advertisement daemon (radvd) is run by Linux or BSD systems acting as IPv6 routers. It sends Router Advertisement messages, specified by RFC 2461, to a local Ethernet LAN periodically and when requested by a node sending a Router Solicitation message. These messages are required for IPv6 stateless autoconfiguration. Linux is supported. Your mileage may vary on BSD. To download the latest version.
