- Use packet Tracer if you're able to get your hands on it. Otherwise you can use GNS3, but for this you need IOS images.
- Use CBT nuggets or INE videos if you're willing to pay.
- Ask al lot of questiosn, even if they're dumb, don't be ashamed.
- Experience, this is the best way to learn. Find a networking job.
