OSPFv3 - The Basics

Tue, 01 Feb 2011 00:00:00 +0000

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. As always, I’m using Cisco routers here. Just as yesterday, this is just a guide to the absolutely basics; if you want to do some funky OSPF magic, you won’t find it here - perhaps in time, though.

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 the IPv6 talk, but let’s start easy and get EIGRP for IPv6 up and running.

Configuration

There are quite a few differences between EIGRP for IPv6 (yes, that’s an official name) and the IPv4 version. First of all, all IPv6 routing is disabled by default on a Cisco router, so, if you’re doing any routing in IPv6, you’ll want to enable it or risk smashing your head into the desk trying to figure out what’s going on.
