I have a 2621 router, because I want an image of about 21M, I upgraded as follows:
IOS = 32M
RAM = 64M
ROM VERSION = 12.2
However, when I power up my router, it goes into a boot loop, and I see the following messages:
NOT ENOUGH MEMORY IN THE SYSTEM TO RUN THIS IMAGE
***SYSTEM RECEIVED A SOFTWARE FORCED CRASH***
how to overcome this error, and successfully upgrade, so I could load my new image?
I've got a Cisco 2621 with this IOS image in flash: c2600-i-mz.120-7.bin (the only IOS in flash). When I power up the router, the following errors occur:
open: file "n" not found
open(): Open Error = -1
loadprog: error - fileopen
boot: cannot load "flash:n"
I have to press "Ctr l" and "break" to enter Roman, there i can use the boot command to start the IOS. Configuration register is set to 0x2102, all running config should be factory default.
What I have to do to boot the IOS directly when i power up my router (without entering Roman mode...)?
We are setting up one of these for the first time. It is in a constant rebooting process.
Here is the boot process:

View 2 Replies View RelatedI have a Cisco ASA5505 with Frontier ADSL. I broke into their crappy little modem and obtained the settings needed to replace their modem with a 2621 router with a WIC-1ADSL module. I have a static IP from Frontier which is on my ASA5505 and the Dialer interface on the 2621 gets its address from Frontier via DHCP. There are devices behind the ASA which I need access while in the field, IP Cameras, Seed Treater, etc., so I have Anyconnect running on the ASA and can access everything from my laptop, iPhone and iPad from whereever. The issue arises when my laptop is in house and communicating with my parent company and I try to make a cell phone call off the network extender. The call is choppy since there is no QoS and the data is strangling the voice. Since I have control over the 2621, I added another network and NAT it into Frontier without them knowing. I have since placed the network extender on this network as well as a WAP200 that is wide open for my customers when they are in the office. Doesn't fix the problem but...
I have now added Evertek Wireless internet with a static IP also but they use a reservation based on the MAC Address of my interface of the ASA. This plugs directly intot the ASA via ethernet (I would assume their antenna is just a wireless bridge). I set route tracking on the Evertek side and use the Frontier as a backup and all devices on my NAT network still funcion on Frontier DSL and all my nornal data traffic is out Evertek. The issue is that the Evertek Wireless is not very fast or reliable (today in during a snow storm, it could barely keep an internet connection). And I had a problem with Anyconnect using either connection. I got that working. But think that the "ip address x.x.x.x y.y.y.y dhcp setroute" on the Evertek side messed things up from a routing standpoint when I would connect from the outside on the Frontier side. For testing, I switched the tracking around and now the connection on the Frontier side does not work but that is besides the point.
Frontier is going to try out an ADSL/2 connection next week which brings up another issue; all Frontier connections come into my buidling on a single 4-pair wire so if they go down, all my internet except the Evertek goes down. I have a Raven Slingshot coming for installation shortly that cannot go down; it will provide RTK (sub-inch accuracy GPS) to my customers that have auto-steer and auto-shutoff capabilities in their tractors via cellular data modem. So, while they are planting their crops in the field, if my connection goes down, their tractor will not function.
I also had a Cisco UC320W but it died a few days after it went off warranty so I replaced it with a Dell Server running 3CX IP PBX that supports Cisco SPA525G2 and SPA501G IP Phones. There is a 3CX iPhone app that allows me to receive calls while in the field, it uses a proprietary tunnel that I have open on the ASA. With 4-pair coming into my building, I will be left with a single 1-pair for phones so I am considering a SIP provider instead.
Can/should I move the Evertek ethernet to the third ethernet interface on the 2621 and track the Frontier DSL against the Evertek (backup) on the 2621 side and use the ASA to track the ADSL/2 against the 2621? Should I acquire an 1841 (or some other device that suppports the HWIC) with a ADSL/2 card and use HSRP between the 2621 and 1841? Is that even possible?
I need to setup a vlan between the 6509 and 2621 router. This needs to be a VLAN (200) the runs between the devices that uses DOT1Q trunking. The end result is all the networks (vlans) on the 6509 can talk to the LAN on the 2600 (10.133.22.0 / 23) and visa versa.
Device 1

Config I did on the MSFC:

I've came across a very odd topology to deal with where everything is connected to everything, without proper utilization of VLANs.
- I've an L3 SW and a 3745 RTR at core
- Both are carrying same subnet to an L2 distribution switch that connects server farm within the same subnet (i.e. 1.1.3.x subnet)
- The L2 switch works as a passive switch, hence another network say, 1.1.2.x has been plugged into it as well.
- This L2 switch extends to other switches without configuration of any VLANs or STP and distributes 1.1.3.x network.
Periodically and unexpectedly, the router starts hanging and utilization goes beyond 80%, and there's nothing at all that is observed in "sh proc cpu" to be eating router resources. Its quite difficult to observe the pattern, as its random.
I've bought my E4200v2 via eBay, because original Cisco store doesn't ship to my country (Israel).My first unit was... defective, I think I wrote about the issue on this forum a while ago.It had connection troubles, always in a dead loop, saying "Connecting..." one to 100 times it managed to connect, and suffered slow internet connection speed, where all speedtests gave me 60% of my actual internet speed.Which is 30mbit.I'm sure about my ISP, it uses next.gen technology, they have their own underwater optic cables. Without Cisco router, only dialer, I get 100% of my internet speed, or with another router as well.I decided to RMA my e4200v2.
Out of context question: Why there's no option to specify server name instead of server IP? our ISP uses domain name for connection, rather than IP address, as they have a lot and a load balancer above 'em.Now, to the original issue.Refund is no option, RMA again is no option, too much time and money.Maybe there is a solution? It just can't be the reality, that two out of two units are not working. I heard this router is very good. And I heard the v1 is working very well in Israel. so It can't be our country that is the problem.By the way, I've called my ISP and they've switched me to MPLS connection for a try, so in a router you just switch to "Automatic configuration - DHCP" and it pulls IP, DNS servers and connected to the internet, but was hooooribly slow.
So I'm back to dialer. the main still is the "Connecting..." loop, sometimes says "Connected" for a second, and then connecting again... It manages to pull DNS addresses though, but never the IP and never managed to stay connected.All the connection configs are very basic, you know it. Server IP, username, password, keep-alive, MTU (I've tried auto, and a ton of other combinations recommented by our ISP or Cisco).My latest idea was to film how I burn it or throw a rock at it and send to Cisco the video, but that's kinda too much, it's too early for such decisions, especially when already $300 were spent.
My WRT310n router, since yesterday, stopped working "normally".It was disconnected from the power plug in order to put it in another shelve and when I plugged it in, voilá, constant reboot.I keeps rebooting forever... I can't even make an ethernet connection. Reboot, after reboot. Tryied to make a reset with no luck, 5 seconds reset, 30s reset, pressing reset while plugging it in.Even with nothing connected to it (neither wireless nor lan), just the power plug and it keeps re booking one after another.

OPTEMAN: 3 routers connected via a private subnet (/29) over the OPTEMAN: Site A, Site B, and HQ. Site A is a 3560 that is the gateway for two subnets: siteA1 and siteA2. SiteB is a 2621, and HQ is a 6509 w/ MFSC.
HQ also connects to 4 other sites via MPLS: SiteC, SiteD, SiteE, and Site F.
HQ has the server subnet, Internet connection, and connection to other services via MPLS.
I have basic EIGRP setup on HQ, SiteA, and SiteB. So far only siteA and HQ are updating each other. Not sure why. I am looking for the best practice example of how I should setup my enterprise EIGRP. I currently use static routes between the sites. I would prefer to be able to setup EIGRP in parallel, the remove the static routes.
I have a spare 2621 sitting on my desk and i would like to run a little experiment. i had two LAN segments that are seperated right now, but would like to stick this router between them and route traffic between them?

How would I go about only allowing the traffic that I have acl's set for and blocking any other traffic?
Just as an example say I have an acl that allows traffic from 192.168.1.0 to 192.168.2.10,How would I go about setting it up so that no other traffic can occur such as http traffic from 192.168.3.20 to 192.168.1.10
I'm hoping there's a way to deny everything and then only allow what I want. It would seem crazy if I would have to deny every single protocol from every possible action.
I have a 2621 that I am configuring on the internet. My ISP gives me a static DHCP assigned address and then two more static addresses that are not part of the same block. (e.g. 1.2.3.4 is static via dhcp and then they give me 5.6.7.8/30).
I have fa0/0 getting 1.2.3.4 ia dhcp. I have 5.6.7.8 on a loopback interface for PAT/NAT as I have the main one on fa0/0 doing vpn to a remote ASA. The problem is that I have yet another device that needs a public IP, mainly 5.6.7.9... I want to hook that device up to fa0/2 (this box has three fa interfaces). How do I setup fa0/2 if I want to give the device on it a real live public IP address? I have done this before, but it must have been 10 years back on an even older CISCO and I can not remember how I did it.
We have an existing Cisco 2621 XM router with an ADSL interface connected to BT Broadband. Basic layout below:
Internet------ADSL on Cisco 2621 ------ Pix 506e ---- 3600 switch with inter VLAN routing to multiple VLANS
There are 5 static IP addresses. The internal FE port on the 2621 has one external assigned to it. The outside int of the PIX has another external IP assigned from the 5. The other 3 are NATd through to internal IPs via the PIX to internal servers etc.
The ADSL is being upgraded to BT Infinity. This new service comes with a separate VDSL modem and a separate BT router. Ideally I want to ignore the BT router and use the Cisco 2621 as it has 2 FE ports and I suspect I could do something using PPPOE.
So New layout would look like
Internet ----- BT VDSL modem------ Cisco 2621 ----- Pix 506e ---- 3600 switch with interVLAN routing to multiple VLANS
I think it is a bit strange the way it is setup as 2 static IPs cant be used. There is an opportunity to use a ASA 5505 which may become available.
I'm moving into a new data center. I don't consider myself a network engineer or anything but I do understand the basics. The new data center I am moving into routes my network to me a bit differently than my old data center. The IOS on the Cisco 2621 is: c2600-i-mz.123-26.bin
I am assigned a /29 block which they configure as the routing network, it looks like this: Routing Network: A.A.A.0Routing Network Sub net Mask: 255.255.255.248Routing Network Def Gateway: A.A.A.1Customer Usable Address: A.A.A.4
I've been assigned a /28 block which is B.B.B.240/28. They stated that in order for me to use my allocated blocks, I had to act as my own gateway, routing the traffic through the routing network. This goes just a bit beyond my networking knowledge, though I still understand it, I just don't know exactly how to execute. I'm assuming my 2621 with 2 Fast Ethernet interfaces should be able to handle this routing scenario.
Any sample configs, or possible a link to a how to to get this setup? I was going to use FreeBSD to do the routing, but a appliance based Cisco router is much more attractive of an option to me.
My main issue was trying to connect virtuelly via GNS3 and my router setup on it. I have three Cisco 2621 XM routers set up. They all came with 2 Fast Ethernet ports. However, only one of them has a Serial port. So, what I'm doing is connecting the routers together with the fast ethernet ports using crossover cables. So, I baselined two routers to start with. Very simple AAA, set up IP HTTP server, IP HTTP Secure Server, etc. Privledge lvl 15 access, etc.
I then set my Router A's inside Fa0/1 port with a 192.168.1.0/24 network. The outside port Fa0/0 is 10.0.0.0/30 network.Router B is set up similar, 192. 168. 2. 0/24 insice Fa0/1, Fa0/0 is 10.0.0.0/30 network outside. So, three networks 192.168.1.0, 192.168.2.0, 10.0.0.0 network. [code] I then repeated the same on Router B, just transposing 2.0 network for interesting traffic, and Peer 10.0.0.2 for the Fa0/0 interface on Router A.When I "test" the tunnel, I get an error message. So, since I'm connected to Router B (which was working, had routing, and had Router A's network 1.0 in it's routing table), the error msg says that I need to add a route into the routing table (192.168.1.0). It was there up until I attempted to put the VPN in place. It's like it stopped the routing.
At face value, it looks like this should be working! But when I debug the ospf process, it looks like hello packets aren't tranversing across to the other side. Is it because I just have the 192.xxx.xxx.xxx networks as "interesting" traffic? Can I have multiple networks marked as "interesting"? I thought that's what the peer statements were doing to allow the tunnel to be established.

This used to work on a Windows 2000 server which sat on different piece of hardware, but stopped immediately after the migration to Windows 2003 server was done. There was no change on the router or switches prior to or after the server migration. I see DHCP server log on the 2003 server giving DHCP NACK because the phones are apparently asking for IP's in the data VLAN.
I've got a 2621 configured as my main gateway to the internet - right now it's obtaining a DHCP ip from a the ISP's proprietary router set to bridged mode.
As of now, I'm unable to ping the internal interface of the router. I can ping external IP's only, even though I have DNS servers listed, i am unable to resolve host names. I'm running a few servers to which people are able to connect to my web server, among other services. I even have a crypto map setup to another 2621 across the country and can ping all internal ips on the other end... I JUST CANNOT PING THE INTERNAL INTERFACE of the router!!
I've noticed that when I ping the router during it's boot process (using linux un-interupted) I get a response in a very short window, then dies again. I'll post my config below:
