Detailed explanation-1: -In unicasting, the router forwards the received packet through only one of its interfaces. In multicasting, the router may forward the received packet through several of its interfaces. Emulation of multicasting through multiple unicasting is not efficient and may create long delays, particularly with a large group.
Detailed explanation-2: -In multicast communication, there is one source and a group of destinations. The relationship is one-to-many. In this type of communication, the source address is a unicast address, but the destination address is a group address, which defines one or more destinations.
Detailed explanation-3: -Concept: Dynamic routing, also called adaptive routing, is a process where a router can forward data via a different route or given destination based on the current conditions of the communication circuits within a system: Explanation: There are several protocols that can be used for dynamic routing.
