During DR election, the router OSPF priority is checked first. If this is a tie, then the OSPF RID is used to break the tie. Is OSPF priority changed at the global configuration level or the interface level? Can each interface on a router have a different priority? Neither Odom's book nor Lammle's book has the command, but Bryant's ebook shows it as an interface level command: ospf priority. If I change the ospf priority of a serial interface but also have a loopback address configured, would the OSPF priority be the priority of the loopback? Is this shown with show ip interface lo0 command? Sorry to be so dense, but being a unix admin, I don't have a network to test on. Also, when I loaded Lammle's cd and ran the test, during the simulation, I had to create a connection and search for all the settings for the console connection to the router. Will I have to do that on the test as well, or will I get a console prompt by just clicking on a host (as other simulations do)?
