Workbooks?

Hello  :)

I'm trying to look for some kind of workbook to practice my networking skills with the different concepts I learned (OSPF EIGRP VPN Etehrchannel ect..).  I remember when I was in elementary or even middle school, they used to give us these math workbooks that had all sorts of world problems. We used those to test the concepts that we learned. The more word problems you did the better you became at solving word problems. Is there something like that out there for networking concepts? Ive seen free lab websites but they basically teach you the concept and have one lab to do at the end. Im looking more for like (as an example) 10 different scenarios and we have to implement ospf or eigrp or other protocols.
