I've searched on the Internet what's the best router for a CCNA lab and learned from Wendell Odom's blog that he chose the 1700 as the winner. But the idea of having a "wired" router doesn't appeal to me when networks nowadays have converted to wireless. It's still cool though to have a 1721 router someday for my lab (if budget permits it).
So I've decided to buy a Cisco 871w router on Ebay, which supports wireless (not to mention IOS 15.0), not too long ago and replaced my existing Linksys E1200 at home. I've configured it one night and here's the configuration that worked for me and the troubleshooting I went through. Another cool thing having this router is that I can configure it remotely using my iPhone or iPad with this free app.
We configure a bridge group and enable IRB (Integrated Routing and Bridging) to "bridge" network traffic and routing protocols between a logical bridge interface and the routed (Layer 3) interface.

I was pulling out my hair at this point while figuring out why the router doesn't get its dynamic IP from the ISP. So I ran some debugs to dig further.

I've hardcoded these commands under the FE4 (WAN) interface since I suspected the MAC address of my Linksys E1200 could still be cached or locked at the ISP side. After rebooting the cable modem and then BOOM there it was, I've finally got an IP address.

So I've decided to buy a Cisco 871w router on Ebay, which supports wireless (not to mention IOS 15.0), not too long ago and replaced my existing Linksys E1200 at home. I've configured it one night and here's the configuration that worked for me and the troubleshooting I went through. Another cool thing having this router is that I can configure it remotely using my iPhone or iPad with this free app.
We configure a bridge group and enable IRB (Integrated Routing and Bridging) to "bridge" network traffic and routing protocols between a logical bridge interface and the routed (Layer 3) interface.
