Welcome!

Sun, 2005-12-25 20:03

Hello everyone! I'd like to welcome you to the Cisco Blog! I don't know
about you, but there are times when I have those unanswerable questions
or just a flat out weird network configuration I'm trying to set up...Or
even those times when you're looking over someone's shoulder as they
are setting up a router, and you think, "wow! I didn't know you could do
it that way!" (but of course, never say anything for sake of your own
pride). Well, that's why I created this blog - to give a forum to all
interested in the topic of Cisco. Feel free to post about anything Cisco
related: questions, comments, configurations, tips...whatever.
Just a quick run through the few rules-of-the-blog:
1. Keep the language clean
2. Try to keep the topics centralized around Cisco technology
3. Invite a friend!

That's it! Post away!

Update: As of September 2010, Cisco Blog is now Tekcert.com

Alias me!

There are quite a few very cool commands in the world of Cisco, but there is one that stands consistently at the top of the heap. It is one I type on every router, first thing. The column-based, concise, cleanly output…the one, the only:
Router#show ip interface brief
Pop! The one firework just went off. Seriously though, that is an awesome command. The only problem is that it takes too long to type. If I want to see the status of all my interfaces quickly, I want the command I type to be quick. That's where the alias command comes into play.

Basic PIX Configuration

Everyone needs a good, basic PIX Firewall configuration on-hand from time to time. Here is one I set up for a client that does the following:
1. NAT overload from an inside network to an outside network
2. Accept incoming PPTP VPN connections from ouside clients
3.

Build a router on Linux

Although this is not directly related to Cisco, I found it quite interesting. For those of you looking to build a cheap (aka FREE) Cisco-like router on Linux, you are in luck. Jump to Google and do a search for Zebra RPM. I use this little widget to simulate other routers on a network. It supports all major routing protocols, even BGP!
Actually, try this site - it might be a little easier than Google to find it:
