Glossary A Term RADVD (Router Advertisement Daemon) Request to Send (RTS) Threshold Routing Information Protocol (RIP) Definition RADVD is an open-source software product that uses the Neighbor Discovery Protocol (NDP) to listen for router solicitations in the IPv6 LAN. It responds with router advertisements to support stateless address auto-configuration. When a new host connects to the network, it sends a request for its configuration parameters, and the router responds with a router advertisement packet that contains the network-layer configuration parameters including IPv6 prefixes. The node takes the prefix and extends it to a full 128 bit address by adding an EUID based on its hardware address. The packet size, in bytes, that requires an RTS/ Clear to Send (CTS) handshake before sending. A low setting can be useful in areas where many client devices are associating with the wireless device, or in areas where the clients are far apart and can detect only the access point but not other clients. Although a low threshold value consumes more bandwidth and reduces the throughput of the packet, frequent RTS packets can help the network to recover from interference or collisions. This protocol uses use distance vectors to mathematically compare routes to identify the best path to any given destination address. RIP sends routing-update messages at regular intervals and when the network topology changes. Upon receiving a RIP message, a router updates its routing table and transmits the updates to other routers. RIP prevents loops and has features to provide stability despite potentially rapid changes in a network's topology. RIPv2 supports subnet masks, allows more information to be included in RIP packets, and provides a simple authentication mechanism that is not supported by RIP. Cisco RV220W Administration Guide 163
