Line 9:

#A new routing table is constructed based on the old routing table in each router, and the new information received from other routers. The hop-count is used as a speed measure for the path. The table also contains a column stating which router offered this hop count, so that the router knows who is next in line for reaching a certain network at a certain speed.

#The table is then purged from bad routing paths. If two identical paths to the same network exists, only the one with the smallest hop-count is kept.

#The new routing table is then communicated to all neighbors of this roterrouter. This way the routing information will spread and eventually all routers know the routing path to each network, which router it shall use to reach this network, and to which router it shall route next.
