This isn’t hard stuff at all. I’m sure there are a couple of cool tricks I don’t know yet, but let’s try anyway.
Here’s a story from last week with little of no teaching value. I got a call from one of our business units looking for some routing help. We don’t usually care about their production networks, but they were seeing some funky traceroutes, so I agreed to try and help them out.
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 up a quick lab to see for myself. Sure enough! That’s exactly what I saw.
Corrections are always welcome.
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
EIGRP allows you to tag external routes. That is, any route redistributed into EIGRP can be tagged with a numeric descriptor from 0 to 4294967295. Aaron ConawayI like to lean my head to the left, hit it with the palm…
