Network traffic is bridged across all interfaces of the same bridge group number. A: 10.0.0.0/8 ------------------------------------------------- This routing algorithm group repeats the number of hops in a given route, requiring each router to send its complete updated routing table, but only to its neighbors. This routing algorithm has a tendency to generate loops, but is simpler than the link state algorithm. See link-state routing al-gorithm and SPF . Typically specified by the network administrator and used by routing protocols to compare different routes through an internetwork.
