I was studying via Google+ Hangout the other day with CJ and Rob, and one of the topics that came up was the idea of OSPFv2 advertising all loopbacks as 32-bit no matter what the configured mask is. I rarely use loopbacks outside of a lab and had no idea, so I set...

Redistribution Notes – Tagging
You can use route tags in redistribution scenarios to filter and/or manipulate routes.

You can configure an EIGRP router to filter routes from being advertised or from being accepted.
Routing IPv6 with BGP – The Basics
Are you sensing a theme lately? Since we covered the basics of the main IGPs (I'm an enterprise guy, so no IS-IS comments, please.), I thought I'd try to describe the basics of advertising IPv6 routes over BGP. Yet again, we're not going to do any route manipulation or change any of...
OSPFv3 – The Basics
A few hours ago, the last of the IPv4 addresses were allocated by IANA. Now's the time to learn more about IPv6! Yesterday, I posted about EIGRP for IPv6, so I think I'll continue the trend by introducing OSPFv3, which is the IPv6 implementation of OSPF

ROUTE – Epic Win!
I passed the ROUTE test today. I don't know what I'm going to do with my evenings now.
ROUTE Notes – Further IGP Redistribution
What's this? More IGP redistribution? Yes. Yes, it is.
