Routers - Flooding, Advertising, & Pruning Protocol

The animated TECHTip Tutorial is available here.

The “flood” process is how routers accumulate their state (routes) information (multicast trees). That is, routers “advertise” their routes (addresses) and operations (available, busy, and broken).

The “prune” process is how routers eliminate their state (routes) information (multicast trees). IGMP [Internet Group Management Protocol] (routing protocol) is used between IP host routers and their immediate neighbor (routers) multicast agents to support the allocation of temporary group addresses and addition/deletion of group members. IGMP is used by routers to discover (advertise) group members. Multicasting routing protocols (how packets get from one place to another) portend (possibly) to provide fault tolerance (alternative delivery methods), error correction, load balancing (to avoid traffic jams or congestion) and improve performance in an increasing complex Internet Web of wired, wireless, and any media communications.
