   • All the ports of the root switch are designated ports.

   • If static route preference is 255, the route cannot be used.

4. Refer to the graphic, which of the following statements is true about OSPF topology and configuration?

   

   • A stable OSPF neighbor relationship can be set up between R1 and R2.
   • After the default network type of the interface on R1 is restored to broadcast, a stable OSPF neighbor relationship can be set up between R1 and R2.
   • After the default network type of the interface on R1 is restored to broadcast and the hello packet sending interval is changed to 10s, a stable OSPF neighbor relationship can be set up between R1 and R2.
   • Compared with R1, R2 is more likely to become the DR because the DR priority of the interface on R2 is lower than that of R1.
