The diagram above shows the network from the viewpoint of Router A. Router A can reach
192.213.11.0 through Router B with a cost of 10+5=15. Router A can reach 222.211.10.0 through
Router C with a cost of 10+10=20. Router A can also reach 222.211.10.0 through Router B and Router
D with a cost of 10+5+10=25, but the cost is higher than the route through Router C. This higher-cost
route will not be included in the Router A's shortest path tree. The resulting tree will look like this:
128.213.0.0
Router B
192.128.11.0
Router C
222.211.10.0
