Thanks Dan, I hope you mean Oct 4 though.
CIT is basically all about troubleshooting: so you need to know what to look at in a config that means it won't work, such as mismatched duplex, wrong lmi keepalives, mismatched k values, ISL where only dot1q will work, RIP v1 limitations etc. You need to know EIGRP, OSPF multi area, and what causes SIA, redistribution problems etc. You don't get hardly any BGP or ISIS so do't worry about them too much, but you do need solid knowledge of ISDN, PPP negotiation, CDP, VLANs, VTP.
It's a bugger really, but i am so so glad to only have the 3 BSCI textbooks on my kitchen table now instead of those 3 plus 2 BCRAN, 2 BSMSN and 1 CIT! I took the Cisco CCNP course (BSCI was 18 months ago) so I use the course textbooks which are great.
Good luck dude.
