I have been saving money to build my ccna voice lab. Recently I bought 2600 and 1700 series routers.One of the 2600 router needed a password recovery so after a refreshing nap i got to work.
During the password recovery procedure, I mistyped confreg 0x1242; by the time I realized my mistake, my computer screen was full of "C" characters Now the whole story is i can not console into it.
Edit:After some research, I found If I use the baud rate 1200 in hyperterminal.i will be able to console into it.When I did that, I noticed that Rommon kept incrementing as:
the other similar resolutions on the cisco/other website but none of them works for the Cisco 4506 switch I have.
1. Reboot
2. Press the "CTRL + C" button on the laptop to put the router into ROMMON mode.Result: Works fine and gets into the ROMMON 1 mode.
3. confreg 0x2142Result: This one does not work. confreg=0x2142 and that command is accepted by the switch but it does not tell us that we have to restart to make the changes. Now it goes ROMMON 2 mode.
4. resetResult: I type reset and the switches seems to be power cycled but it again goes to the password prompt which I dont know and this is the password that I am trying to recover or break.
I am connecting a 2600 router to an ISP. Interface 0/0 is connected to the ISP using DHCP. Interface 0/1 is connected to the inside providing DHCP services to the inside. At least it should only be providing DHCP services to the inside. I also have a public static IP that is NAT to a private static IP. Everything is working except the computer on the static IP. From the router I am able to ping inside and out from each interface. I am able to ping both interfaces of the router from the computer on the static IP but I cannot ping outside the router. If I do a debug all I see a reject for the gateway of the static IP but it has “mobile IP” in the text string. Not sure what mobile IP is relating to. Networks are as follows:
0/0 DHCP 10.X.X.X 0/1 192x.x.x Static 75.X.X.X no ip dhcp use vrf connected ip dhcp excluded-address 192.X.X.1 ip dhcp excluded-address 192.X.X.2 ip dhcp pool CLIENT
I have a 2600 Router series and I cannot remember the Password. I have tried following web pages that state to use control Break on the boot up but its not working.can reset that pw and write erase my configuration file?Here is my boot up. I have tried hitting control break at the very beginning over and over and then again when at the cold boot it has not worked....

I have a cable modem with my 2600 Router and i have a little speed problem when I'm going out to the web via my F0/0.. according to regular speed test sites my speed is around 20mbps but when i hook up to my modem directly i get a solid 40mbps.. now I've changed my Cat 6 cable from my modem to my router and this are my settings in the router.

I see some drops and lost carriers but not sure what those might mean?
I recently lost my configuration when attempting to reset the password for our Cisco 3560g switch, the switch connects to a Cisco 4506 switch via fiber back to our main office.
I have the switch temporarily routing all traffic to our 4506 by using the default route of 0.0.0.0 0.0.0.0 10.10.10.254 but the same switch is connected to a cisco 2600 router that is on a 10.10.20.0 network and the 3560g is on a 10.0.0.0 network.
Host computers sit on the 10.0.0.0 network, but they need to go to the 10.10.10.0 network for internet, domain, etc the same computers need to go to the 10.10.10.20 for remote connections and other services.
The address of the 3560g is: 10.0.0.254 The address of the 2600 is 10.10.20.2
When the default route is set to 0.0.0.0 0.0.0.0 10.10.10.254 (4560 switch) domain browsing works perfectly When the default route is set to 0.0.0.0 0.0.0.0 10.10.20.2 (3560G) switch I can ping any ip address in that range and the address on the other interface ip adresses on the 2600 (eg. 10.10.30.1 / eth2, 10.10.40.1/ eth3 etc.)
I have tried to weight the routes after adding them both to the configuration, but that doesn't seem to work at all.
The switch connects back to the office via vlan1 (10.10.10.253) The 2600 is connected to port 1, which belongs to Vlan2 (10.10.20.1) And client computers sit on ports 2-12 belonging to Vlan10 (10.0.0.240)
So in a nut shell, how would I go about setting it up so the machines on 10.0.0.0 can connect to 10.10.20.0 and 10.10.10.0 and vice versa at the same time? Everything was working fine until I rebooted the switch (3560g), which makes me think the person that configured this before me didn't save the running config to the start up config.
My network generally runs older routers (2600 series) with 16 port switch modules (NM-ESW-16). This has always worked great since I can configure the router and the switch ports on the fly, making changes to either as necessary. Well I am upgrading to 2811 routers, and we wanted to get gigabit ethernet ports on our switch modules. I think I made an error when I purchased a few of these switch modules: NME-16ES-1G.
The first problem, is that the switch ports don't even show up on the router config, I have to establish a session into the switch, (And I can't seem to get back to the router unless I manually switch off power and restart). I don't like this type of switch module, it's like I'm running a completely separate device, and while having a layer 3 switch is cool, It doesn't let me setup routing protocols so I don't like doing it this way. I want to go back to using a switch module that simply adds a ton of ports to my router like the NM-ESW-16. (Note: The NM-ESW-16 does actually work in the 2811 and would be perfect if it were Gigabit speed.)
The seconds problem is that the NME-16ES-1G isn't actually a Gigabit switch. It has a single gigabit port, but the 16 ports are all Fastethernet, and not gigabitethernet. So ideally, I am looking for a switch module that I can fully configure from the router interface that has 16 gigabitethernet ports, and works with a 2811. IE I want to do this. [code]
We have two MPLS circuits managed by two different suppliers, one carries VOICE the other DATAWe are to decommision the VOICE MPLS and have increased the bandwith of the DATA MPLS to carry VoIP traffic too.
At both of our sites A & B ,devices connected to the LAN have a default gateway of the VOICE providers Cisco 2600 router , which then goes into the LAN switching. (see diagram)So what I am trying to achieve is toto simply replace these 2600 routers from the VOICE MPLS provider with our own so we dont have to change the default gateways at both sites. Testing
Our Cisco 2600 routes are plugged into each LAN switching environment with two subinterfaces configured, one for voip and the other for dataThe problem is from the router and respective subinterfaces we can get to the other sites destination without any issue, but if for example a user is at site A with Ip address 10.16.11.12/16 they cant ping the VOIP subnet at site B 10.3.11.0/24. But If a ping is issue from the Site A test router then the 10.3.11.0/24 subnet is reachable but only on the 10.3.12.0/24 configured subinterface.So i guess what Im saying is 10.16.0.0/16 from the LAN needs to be able to get to 10.3.11.0/24Note at site A 10.16.0.0/16 & 10.3.12.0/24 can communicate no problem and at site B 10.207.0.0/16 & 10.3.11.0/24 can communicate no problem.We are using IP routing, should we be using route-maps?
I need to configure an existing 2600 router to use dynamic NAT for access to the web and ALSO I have (5) fixed IP addresses for use with an email server, a web server, and (3) future servers. I do not know the concept of how to set this up. I'm currently using dynamic NAT for the web and this seems OK but I dont know how to map my fixed servers. I assume this is done with static NAT. Do I need to add sub interfaces on the S0/0 T1 interface for each of these fixed IPs? Then do I somehow do static NAT on these fixed IPs to their respective servers?
i have a simple router on a stick config which is providing dhcp to a customer SSID. however i don't want employees to stay on it and eat the band width since its open. the lease is set to an hour, is there anyway that i could set it so that once your lease expired it can't be renewed for 4 about 8 hours? I am using a cisco 2600 router in this setup.
- I have an older router 2600 running 12.1(4) IOS. - There are a few clients connected to it via the frame relay connection. - There is an IP that clients access 192.168.1.10 for example - We need to do a NAT for this IP for one specific client only like "ip nat inside source static 192.168.1.10 1.1.1.1" - However if I do that, that will effect other clients too - On the interface for this client I'll be using "ip nat outside" - Is there a way to accomplish this without effecting other customers?
I've been working with these two Cisco devices in my home off and on for several months now but I just can't take it anymore, I'm about to throw them away and go back to Linksys router.
I have a Cisco 2600 Router with only one Ethernet card in it so I have to trunk from my 3550 Switch to that device. I'd like to have my ISP and all users plug into switch and all trunk back to the router's sub interfaces. Currently, I have started over...again, and am unable to simply get the router and switch to ping each other if I put sub-interfaces on the router. See my configs:
2600 ROUTER: Router#sho run Building configuration... Current configuration : 555 bytes [code]......
3550 SWITCH: Switch#sho run Building configuration... Current configuration : 2302 bytes ! version 12.2 [code]..........
Port F0/24 is in VLAN 1, as are all ports but Port F0/1 which is my desktop PC. I mocked it up in Packet Tracer and it works just fine. This is just a simple setup and I'm making sure I can ping between switch and router before I move to each next step.
I am trying to configure SDM 2.5 on a cisco 2600.I have access via telnet to the router and was able to change the enable password - which i think is level 15 (right?) and setup (and bring up) the ip on the ethernet interface. I can ping - and get response from - the router Trying to install SDM on the router i need to provide the default username i tried both admin/administrator but SDM can't communicate with the router?
We have recently leased an internet connection in our office which comes from the service provider as radio link and BW is 2M. I have clients more than 60 that will share the connection and access internet. I have configured a Cisco 2600 router as below:
Building configuration... Current configuration : 988 bytes ! version 12.2 no service single-slot-reload-enable no service timestamps debug uptime no service timestamps log uptime
[code].....
So far I have read regard NAT it degrades performance as it need to translate every data packet comes from the source and goes to internet. So a question comes in my mind is there any other way how I can share this connection among users with private ip address? Or NAT is the only method to share internet connection among users with private ip addresses?
I'm trying to configure a disco router 2600, my internet connection is via a cable modem. I get a dynamic IP from the cable modem but when I ping to any external IP I have errors.Copy show config and show interface f0/1

I have a Cisco 2600. I would like to know how to redirect traffic going to a certain IP address three hops away to an IP address on a locally connected segment.
Ex. Packet leaves a device with source IP of 10.10.10.10 and destination of 20.20,20.20 When the packet hits the router (10.10.10.1) I want the router to redirect the destination of 20.20.20.20 to 30.30.30.30 (locally connected segment).
The router has two physical interfaces.I am thinking along the lines of creating a VLAN with an ip of 30.30.30.1 and then doing a NAT translation from 20.20.20.20 to 30.30.30.30.
We have Cisco IP phones behind a 2600 series router:Most of the time when the PBX receives a packet from the phone, the source IP of the packet is set to the public IP of the router (1.2.3.4) as expected. However, once in a while, we get packets (at the PBX) with the source IP set to the private IP of the phone (10.0.0.12).The router is configured by our provider, and they can't give us any explanation for this behaviour. Is it safe to assume that PAT is not configured properly at the router?
So I have a 2600 that I have configured three sub interfaces on. FA0.0.1 is set for DHCP and supports VLAN 1. FA 0/0.2 for Voice, FA 0/0.3 for Data. I have this router interface plugged into FA 0/24 on my 3550 and the 3550 is configured as a dot1Q trunk (I have attached configs for RTR and SW).I have most ports configured as access VLAN 1 which is where i have my ISP connection plugged FA0/1 on the 3550. When I connect the service provider link FA0/0.1 never picks up an address. If I take my internal DHCP server and connect it to FA0/1 of the 3550 it snags an address almost immediately.In my mind this validates that my config is fine. I also took the same cable from the service provider cable modem and connected it to my laptop and the laptop is pulling DHCP.
How to configure my serial modules on my 2600 and 3640? Each router has the WIC-2T with two cables connecting them. I tried to ping one router from the other, but no luck. Serial IP address I just made up, this is my home lab, so if I messed those up some how,
Here is the running config for each rotuer:
2610: Current configuration : 1071 bytes ! version 12.3 [Code]...
I’m working with a managed switch that has three V LANs setup on it. Recently the domain changed and the wireless V LAN can no longer access the internal website. I found access rules, in the switch that allowed the wireless V LAN to use the DNS server on the private/staff V LAN. Their DHCP scope is on the switch and DNS is set there. The Website is also on the V LAN with the DNS server. This configuration totally cuts out external DNS usage. It stopped working though. It is as if when things switched on the Domain the wireless users were denied DNS requests. The switch was not touched at that time. I’m looking at it though and it seems that I may have conflicting rules.
The version is 12.2. I believe its a Catalyst 2600~ DHCP scopes: ip dhcp pool INSIDE network 192.168.1.0 255.255.255.0 default-router 192.168.1.1 dns-server 192.168.1.6 192.168.1.4 domain-name saline.lib.mi.us ip dhcp pool WIRELESS network 172.16.0.0 255.255.255.0 default-router 172.16.0.1 dns-server 192.168.1.6 192.168.1.4
Here is the V LAN Setup: Interface Vlan1 ip address 192.168.1.1 255.255.255.0 [code]...
Here are two access lists that should be allowing the traffic from 172.16.0.0 into the list IPs/Ports. These do no work.
During my testing I removed the Deny rule and everything worked. deny ip 172.16.0.0 0.0.0.255 192.168.1.0 0.0.0.255
However, the “ permit ip any any “ rule, makes all the port rules pointless because when this rule is in place solo, I can ping and access everything on the 192.168.1.0 network. Is there a way to deny everything, except what I permit? Because when I remove the ip any any, then they cant even get out. Perhaps there a better way to say, the wireless users can get out but only get into the sub net over specific ports? I have a feeling it may have not be thought out entirely when initially created. However, the big mystery is that it worked before secondary domain controller failed.
I have a cisco 877 router connected to our adsl broadband at our head office. I have managed to set this up with Nat and DHCP all working to let multiple users access the internet through our single static ip supplied by the ISP lets say the ip is 1.2.3.4.Our internal network is 192.168.1.0 255.255. 255. 0.I have a draytek vigor 2600 at a branch office set up the same with a static ip addresss supplied by the ISP lets say the ip is 5.6.7.8.The internal network is 192.168.4.0 255.255.255.0
I am trying to set up a VPN between the head office and branch office so the branch office users can connect to our internal server(lets say ip is 192.168.1.2) to receive group policies,access files and also telnet into our database server(lets say ip is 192.168.1.3).I have attached a sort of running config that i have pieced together from bits i have read on this site and others. I have tried these settings and other permutations of these settings but i cant seem to establish a tunnel even though when i show int tunnel0 on the router it says tunnel is up and line protocol is up, if i show ip route it shows that there is an ip address for the tunnel and that is about it(No vpn light on).
If it makes sense and that I have entered the right information? I have highlighted the parts i am not sure about in red(Quite a bit and obviously not the exact settings but what i think it should be). Once all the settings are correct on the cisco will it automatically establish the vpn or do i have to dial it from the draytek.
i want to configure the router for internet access for hosts this is the my pub ip x.x.x.174 and mask 255.255.255.252 this is isp given subnetmask internal ip range is x.x.x.20-x.x.x.254
I have 3 Cisco 2600 routers with the same IOS and memory.One of them has CME...
What would be the best way to copy the CME from the one router over on the other two?Backup my FLASH to my TFTP and then restore to the other two routers?
I have cisco 2600 router. The problem is my router ios has been crashed and i unable to use any mode on my router. I need to install new ios. How can i install or upgrade new ios step by step.
Currently I'm using Cisco VPN client software to connect to a remote IPSec server on the workstations. I want to to configure IPSec client on Cisco 2600 router which connects to the remote IPSec server so the workstations can access VPN subnet without using VPN software. how to configure IPSec client on the router?
We have an old Cisco 2600 series router, running a single T-1 line, AT&T is the carrier. Very standard stuff.
The T-1 works perfectly on the old router. Cisco 2600 with a WIC-1DSU-T1 card. We have a brand new 2911 router with a VWIC3-1MFT-T1/E1 card in it. The circuit runs 100% clean and trouble free on the old router. When I plug it into the new router, it shows up/up but has a massive number of errors on the line, and the circuit is not usable. There are no timing slips or anything like that.
I have another site using the same router and card with the same configuration on that T-1 and it works perfectly. Zero errors. This site (in a different city) is totally slammed with errors. We already replaced the T-1 card and still have the exact same issue.
I've actually been doing this a long time, and I've tried all of the usual things, adjusting line build out, changing clock source, checking and re-checking configs. Nothing seems to reduce the error rate.
I personally think it has something to do with the Smartjack. Like maybe their LBO is too high or too low, and the old router card was more/less sensitive than the new one?
This is a layer 1 issue and is not defective hardware or defective configuration. I am looking for T-1 insights or bugs/issues.
I have a cisco 2600 router with 4A/S module, can it become the terminal server? If yes, which kind of octal cable should I choose to connect to other cisco routers console ports?
