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.
Summary Post – Methods to Manipulate OSPF Costs
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.
Summary Post – OSPF Network Statement Order and Matching
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!
Advertising a Default Route Into EIGRP
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
EIGRP and OSPF – Are We Connected?
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.
EIGRP Redistribution – Default Metrics of Connected and Static Routes
I wanted to do some analysis of the EIGRP topology table last night, so I fired up a small lab. I was especially interested in how external routes appear there and compare to internal entries. Like all good scientific endeavors, the whole thing got derailed when I made a realization.
