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. Set the cost of the interface directly – Just give it the number you want. Easy. This is the number

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.

EIGRP and OSPF - Are We Connected?

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.

Recap - Cisco Live US 2014
