Well, never made it to RIPv2 : (. Spent the day taking thorough notes on TCP/IP/VLSM/Summarization/CIDR. Read the first three sections of the Bryant Advantage BSCI Study Guide: IP Routing, DV Routing, & VLSM, Summarization, and CIDR. Will go back through to make flash cards for reminders. Will follow up with IPv6 from Routing TCP/IP Volume I, either tonight and tomorrow, or just tomorrow.
