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 did not receive one here obviously, but I was able to work through it on my own. Thanks.

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...

I did some more thinking about your situation and maybe an extended access list would be more of what you're looking for. You can set the access list to filter any incoming traffic destined for the internet to route out the interface connected to the cable modem. All other traffic for your WAN...

What kind of WAN connection do you have there? You mentioned a cable modem but do you have MPLS, Frame Relay, etc? I'm not completely sure how it works or if it is appropriate here, but there is such a thing as Route Redistribution of traffic. If you know the IP address, you might be able...

From each of your routers, can you please run the following, and then paste the results on here so I can see them? This will give me a better idea of which items are connected together. Thanks. R1#show cdp neighbors R2#show cdp neighbors R3#show cdp neighbors R4#show cdp neighbors.

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...

I changed the config-register to 0x2142 and the prompt went away but when I changed it back to the default of 0x2102, it came back. Now why is that?

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...

Well I should have known better - but I had accidently connected my serial cable to the wrong port on the frame relay switch. :~/ That took care of the wrong subnet problem as well as some interfaces not coming up and others were. I am working on a diagram for you to look at. I am wondering...

The main going I am trying to reach is to create a toplogy that never needs recabling. DLCI's can be changed depending on which routers I want connected and VLANS for the LAN network connections.

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...

Minue - You mentioned these commands in your response ip nat translation udp-timeout <seconds> ip nat translation dns-timeout <seconds> ip nat translation tcp-timeout <seconds> I looked at the IOS Command Reference Guide and they list the defaults for udp-timeout as 300 seconds (5 minutes)...

Looking through eBay - those seem to be pretty pricey. Maybe I can use a simulator for ISDN interfaces for now. Thanks for the help.

Sorry it took so long to reply. Here is my running config. Current configuration : 2015 bytes ! version 12.3 service timestamps debug datetime msec service timestamps log datetime msec no service password-encryption ! hostname DSL_ROUTER ! boot-start-marker boot-end-marker ! ! no aaa new-model...

I have 4-2520 Routers with one of them acting as a Frame Relay Switch. I would like to incorporate an ISDN backup line between two of the routers. Each of the routers have BRI ports and I understand you need a special cable for it. Can someone please guide me in the right direction as to what...

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...

Well I decided to let the modem give the router the 192.168.1.64 IP and the inside network to 192.168.2.0. I know you had suggested the 10.0.0.0 network for the inside, but I had already subnetted that out for the frame-relay portion of the network. As I get into this further, I may decided to...

After accidently breaking my SpeedStream 4100 DSL modem and purchasing an AT&T Modem (Motorola 2210) - I can not get the 2514 to work like it used to. I have Ethernet0 set to accept an IP address from the ISP. The only thing it does now is gives it 192.168.1.64 and the activity light for that...
