Routing / STP Questions

 Someone explain the DR process on ospf a little better for me

And the STP election process of which ports to block.

For STP I understand - lower mac address = root bridge and all but ehh - just trying to figure it how in how they ask on the CCNA test.



Any questions you guys remember that just tripped you up somehow? I'm still in hermit mode and believe I should be ready by Wed night still as long as the next two days of study go fine.

Aderall tomorrow + 6 hours

Aderall tues + 6-8 hours

Aderall Wed Morning - 2 hour refresher.
