Optimized logical tree and routing tables. The logical topology of the example depicted in the previous figure is shown. Addresses are assigned to the children ordered by physical position on the cable. This leads to the routing tables shown on the right, where each node needs at most four explicit entries, besides the implicit routes (own address and default route). Entries in bold are those that describe the tree and are the only ones considered to forward packets. The other entries were added to allow direct communication between nodes within direct visibility
