I am almost finished with setting up my Cisco home lab. I have five 2520 routers and two 2950-24 switches. The underlying frame relay network is as follows: R1, R2, & R3 are connected in a hub-and-spoke network with R1 setup as the hub with a multi-point interface on their own subnet. R4 is...

I am finally implementing a Cisco 2509-RJ Access Server. It get's very tiring swapping console cables back and forth when trouble shooting connections between multiple routers! Anyway,I want to be able to access the rack remotely and my original thought would be to connect the e0 interface...

Can anyone think of an example of when you might have two frame relay switches (routers) connected with an NNI Interface within the frame relay cloud? For my home lab, I have one Cisco 2520 configured as the FRS but I saw an example two connected together. I couldn't think of a reason why you...

The Cisco 2520 Router I am using has this prompt... Router(boot)> I restored the IOS with a fresh copy using my TFTP server. The IOS originally said <invalid checksum>. After rebooting the router it still has the same prompt. Any ideas of how to get rid of it? It never did this before...

Has anyone had luck connecting the ethernet interfaces of several different routers to one or maybe two trunked switches and then assigning the different switch ports to VLANS? I am trying to work on this same type of topology except that the routers are also connected in a full-mesh...

I am looking for a less expensive alternative to the APC Masterswitch. It would be nice to be able to power-on my Cisco rack equipment from the web. Any ideas? Thanks!

Is there a limit to how long NAT translations will remain in the NAT table even after the browsing session has been closed? Do they automatically clear themselves out or do I need to go in and manually clear them out myself? After a long browsing session, the router will lock up because of too...

I would like to incorporate a Cisco Pix 501 Firewall in my home lab environment. I was using the Cisco 2514 to act as my DSL Router but have since gone back to using my DLINK Wireless router. What is the best possible way to accomplish this? I want to set up PAT Translation but also allow for...

I have a Cisco 2514 Router configured as my DSL Router. The External interface is set to receive an IP address via DHCP from AT&T automatically. However, when the power goes out and the modem shuts off, I lose that address and even though the modem gets a new one, the router interface does not...
