Here's my exclusive (and free!) CCNA 2014 OSPF On-Demand Video Boot Camp, tackling OSPF fundamentals and the tricky hub-and-spoke configuration! I also post new (and free!) CCNA and CCENT 2:00 Pop Quiz videos several times a week, from my YouTube channel: Chris Bryant's CCNA And CCNP Training Videos This course covers fundamental link-state protocol theory with an emphasis on OSPF, and it's accompanied as always by plenty of labs run on REAL Cisco routers and switches ... including the tricky hub-and-spoke configuration! Enjoy! -- Chris B.
