27.Traditional network layer packet forwarding relies on the information provided by network layer ( ) protocols, or static routing, to make an independent ( )decision at each hop within the network. The forwarding ( )is based solely on the destination ( )IP address. All packets for the same destination follow the same path across the network if no other equal-cost paths exist. Whenever a router has two equal-cost ( )toward a destination, the packets toward the destination might take one or both of them, resulting in some degree of load sharing.
