Day two and three consisted of IGPs and BGP. Again for these two days there wasn’t any lecture to start the day. On day two, we started out doing three troubleshooting question on layer 2 then we jumped right into a five hour IGP lab. The lab itself had sections on OSPF,EIGRP,RIP and redistribution. It is nice still being able to pick up a few things on redistribution. Any time I hit a redistribution section I always seem to let it get out of hand in a hurry. It comes down to repetition and practice though. The more you do it, the better you become at catching the issues before you even start. The biggest piece of advice I can give is draw everything out before you start. Know where you mutual points of redistribution are and if there are more than one. Know exactly where you are going to get any route feedback and from what protocol. The distance command will forever be your best friend, along with the debug ip routing command. Of course you could always get lucky and just get mutual redistribution between EIGRP and OSPF!

After giving us five hours to work on the lab, Anthony went over each question and explained why we answered it the way we did. I have to give him credit, it is a lot of stuff to walk through step by step. Good thing is all this is being recorded so I can go over it again in a few weeks.
