A Glossary Term beacon interval DTIM (Delivery Traffic Indication Message) dynamic routing Definition The time interval at which beacon frames are transmitted. Beacon frames announce the existence of the wireless network. A DTIM field is a countdown field informing clients of the next window for listening to broadcast and multicast messages. When the Cisco RV220W has buffered broadcast or multicast messages for associated clients, it sends the next DTIM with a DTIM Interval value. Its clients hear the beacons and awaken to receive the broadcast and multicast messages. Dynamic routing enables the router to adjust automatically to physical changes in the network's layout. Using the dynamic RIP protocol, the router calculates the most efficient route for the network's data packets to travel between the source and the destination. The RIP protocol regularly broadcasts routing information to other routers on the network. It determines the best route based on the fewest number of hops between the source and the destination.

beacon interval
The time interval at which beacon frames are
transmitted. Beacon frames announce the
existence of the wireless network.
DTIM (Delivery Traffic
Indication Message)
A DTIM field is a countdown field informing
clients of the next window for listening to
broadcast and multicast messages. When the
Cisco RV220W has buffered broadcast or
multicast messages for associated clients, it
sends the next DTIM with a DTIM Interval value.
Its clients hear the beacons and awaken to
receive the broadcast and multicast messages.
dynamic routing
Dynamic routing enables the router to adjust
automatically to physical changes in the
network’s layout. Using the dynamic RIP
protocol, the router calculates the most efficient
route for the network’s data packets to travel
between the source and the destination. The
RIP protocol regularly broadcasts routing
information to other routers on the network. It
determines the best route based on the fewest
number of hops between the source and the
destination.
