Re: EIGRP authentication using key chain with validity period

Scott,
       I thought that the proctors usually reloaded the rack before grading?
To make sure OSPF DRs were set right and whatnot. I know it can all be
gleamed from configs "ip ospf priority blah" but I thought that they mostly
did show commands to grade you in the scripting. Is bouncing the rack
something they used to do but not anymore?
