Hi, I've got a cisco 877 series router and am using it for NAT and routing through the SDM.

I had to get it as I was using a retail linksys router which gave up every now and then and I was called up to reset it .... basically unplug and re-plug the power cable. So I bought a CISCO router with hopes that I could figure out the configuration.

I've got a very basic understanding of the command line however, I'd like to be proficient enough to do everything from the command line.

Is there some online course that I can do or read up on material and try out some configurations to understand how things work?

I'd like to achieve, routing, QOS for VOIP purposes etc.

I'm contemplating learning QOS on linux and using CISCO as just a Bridge

I'd like to know which route to take from the guru's out there.

Here's  a primer.  Based on your version of IOS, look for the configuration and command guides on cisco.com based on your version.  Here's the one for 12.2


Just google

site:cisco.com configuration guide version [ios version here]

Here is a link a IOS tutorial directly from Cisco.  There are probably others you can find doing an internet search.  It's probably best to start with Cisco.

Have fun!
