Every node of a network has a value which should be made known to all the other nodes. Some arbitrarily placed nodes and links may be faulty, however for each pair of fault-free nodes the number of fault-free paths of length 2 that connect them is linear in the size of the network. Faults are of crash type: faulty links do not transmit and faulty nodes neither send nor receive messages. In a unit of time a node can send or receive at most one packet containing the values of at most b nodes. For every 1 驴 b 驴 n we present an asymptotically time-optimal randomized algorithm to exchange values between all the fault-free nodes with the probability exceeding 1 - n-驴, where n is the number of nodes and 驴 0 is an arbitrary constant.
