OSPF and Loopback Interfaces

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

Some Exercises with IPv6 ACLs

ACLs in IPv6 aren’t that different from what you’re used to dealing with in the IPv4 world. You create a list of denies and permits for use with some other structure like filtering, PBR, and all sorts of other stuff. Let’s take a look at building an

Configuring an IPv6 Tunnel with Hurricane Electric

My ISP at home is great. I have infinite bandwidth because they have no idea how to do any rate limiting. Heck, they’re not even skilled enough to know that I have several public IP addresses from their DHCP server. That means, though, that they’re not ready for

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

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.

EIGRP for IPv6 - The Basics

I'm not going to go all out like Jeremy over at Packetlife.net has, but I'm going to start to discuss a few IPv6 topics. In time (like in September when APNIC runs out of IPv4 addresses), I'm sure I'll ramp up

ROUTE Notes - Implementing IPv6 in an IPv4 Network

Study Questions * Your boss says that ever host in the network needs to be converted over to IPv6 by the end of the day. Which of multipoint tunnels, point-to-point tunnels, or native IPv6 would be the most appropriate to use to help with that conversion? Native IPv6 * The engineering department
