Compare cert salaries and plan your next career move
Use your existing gear. Virtually all the commands will be the same as 15.x. One slight difference is that there will be L routes in the IPv4 routing table shown in IOS 15.x, while 12.4 won't show those same L routes (but it isn't a bit deal). HSRP and GLBP are new, with a bigger emphasis on IPv6, and all of that can still be done on 12.4 with the right feature set. You may want to familiarize yourself with how IOS 15.x is licensed differently (compared to 12.x), but that would be more book learning than hands on practice. Hope that helps, Keithhttps://learningnetwork.cisco.com/thread/54584?tstart=0
