This year’s event had the usual stuff that everyone talks about – breakout session, keynotes, exams, Meet the Expert sessions. Cisco stepped outside of technology this year, though, with the theme of helping others.
I passed the ROUTE exam a few days/weeks/months/something ago and decided to pursue certifications of another sort for a while. The wife and I are trying our best to help the community through our ham radio training, so I decided to go down that path a bit further. One thing I was interested in doing is to do EmComm during declared emergencies. That meant I had to take two FEMA courses online to be allowed in the EOC. I thought they would be terribly boring, but I found them to be quite familiar.
There are three ways to manipulate the interface cost in OSPF. One is very direct, one changes the presentation of the interface, and the other changes the calculations for every interface.
When you configure OSPF network statements, IOS orders them most-specific to least-specific then does a top-to-bottom match of the interfaces. It doesn’t matter which order you put them in, the configuration will always be ordered with the longest prefix matches first. Lab time!
Let’s get an IPv4 default route into EIGRP. There are a few methods to do it. I hate most of them, though. I think it will be obvious which one I like. LOL
For both OSPF and EIGRP routers to become neighbors, their interface’s primary IP address must be on the same subnet. That statement is true. There is a subtle difference between the two, though.
