Cisco WAN :: 1500 / What Router To Chose For DmVPN
Sep 10, 2012
What router would you choose to setup 1500 dmvpn tunnels (mGRE/ipsec)? so this router will be my hub and the hub will have 1500 tunnels.this router with this many tunnels will have to be able to provide excellent service to all spokes/tunnels.the spokes will mainly use the tunnels for business, transfering small files and some email I would say they may transfer 500megabyte of data per day but that's the absolute maximum.

I seem to be having an issue where certain very packets are being dropped/lost by my office router. The reproducible situation is, when I attempt a DNS zone transfer from my linux bind DNS server (A.A.A.A) to any server on my network behind NAT (Y.Y.Y.Y) the first packet (Seq 1) of the response is lost. The client making the query asks for first packet (Seq 1) to be resent, and the DNS server attempts to resend it repeatedly, but those are lost too.

my boss has a vostro 1500 laptop and is constantly losing internet connection. Before losing connection, a little blue world shows up in front of the computer picture in the lower right hand corner and then says *limited access available*, then he can not connect at all. If he disconnects and then reconnects it works for a short period of time and then the cycle begins again. Recently, i was told it was a new router, so we replaced the old router and still having these issues,

My laptop is refusing to recognize the router. Until yesterday everything was fine, now it's not recognizing it at all. There are other computers on the network that connect just fine. When i go to Device Manager it is also missing the following:
Base System Device
Base System Device
Base System Device
Ethernet Controller
Network Controller
PCI Device
SM Bus Controller
Video Controller
Video Controller (VGA Compatible)
Since I can't get onto the internet from that computer, where to go to get the drivers for these to download.

There use to be Cisco 851 routers, but lately these routers are replaced with Cisco 861-K9 routers, and these 861 routers doesn't support DMVPN, instead 851 use to be.
Is there any license file we can upload in 861 router for DMVPN capability, if yes may i know the SKU # for that. We have some customers having 6-7 locations and they are planning to have 2 more locations, we implement already DMVPN in there network, if we go with the 87X or 88X router there price is almost double the price of 861.

I have a new Linksys 1500 router which I am using to replace an older WRT54GS. They are connected to a wired router (BEFSR81) to allow a wireless network to work in conjunction with my wired one. The WRT54GS ran as an access point. The 1500 does not seem to have that option. I have successfully been able to set up the new router and use it with laptops, ipads, etc. Where I’m running into problems is with my Squeezebox. Although I can see the network and enter a passcode into the Squeezebox, it never connects (the light on the Squeezebox is green (acquiring IP address from network). It never gets beyond this point. I have tried: Disabling securityChanging mode from mixed to various optionsDisabling firewallsNothing seems to work

I am trying to spec out some routers for a small DMVPN network.I was thinking 2801's for my hub routers.will these run DMVPN out of the box or do they need additional hardware modules?according to the below linkyou need a "AIM-VPN/SSL-2" module in order for it to work, but then according to"The Cisco 2800 Series supports IPSec Digital Encryption Standard (DES), Triple DES (3DES), Advanced Encryption Standard (AES) 128, AES 192, and AES 256 cryptology without consuming an AIM slot."

Trying to setup a DMVPN on out existing equipment that is currently running all point to point vpn connections. basicly its not working. my best guess is something with the config is interfering but i'm not sure the remote router (881) is always comming back with MM_NO_STATE and the main router(2901) is either MM_NO_STATE or MM_SETUP.
I added the config for the 881, 2901 and a debug crypto isakmp and debug crypto ipsec from both routers. I have verified the Keys are correct and it is not blocking port 500. if i issue a sh crypto isakmp policy they are the same on both routers. if you need me to post anything else i will, one note i removed the configs that were part of the point to point tunnls on the 2901 router.

I have setup DMVPN and EAZYVPN on one router. Tunnel interface on Spoke one and Spoke two are up/up and show crypto ISakmp sa shows both tunnels are in idle. However, tunnel to Spoke one(10.10.1.1) keep bouncing on and off(see below). Every 30 sec or so, the tunnel gone back to IKE phase while tunnel for spoke two(5.5.5.1) still leave active. THe configuration on the HUB side is the same for both spoke!! show crypto ipsec sec shows both side has the same life time(IOS default). Could that be an IOS debug on the spoke one?
Hub :
Cisco IOS Software, 2800 Software (C2800NM-ADVIPSERVICESK9-M), Version 15.1(3)T2, RELEASE SOFTWARE (fc1)
HUB#sh crypto ipsec security-association
Security association lifetime: 4608000 kilobytes/3600 seconds
Spoke one:

Region : UnitedStates
Model : TL-WDR4900
Hardware Version : Not Clear
Firmware Version : 3.13.29 B 130126 R 50426n
ISP : Comcast
1. Any device which is switched off (WiFi turned off) wont be able to connect again without a router reboot. I get a connection timeout error when trying to connect. Happens only when there are more than 3 devices connected. (all my devices are ARP linked to MAC addresses with fixed IP addresses - I thought this would eleminate the problem but not)
2. Streaming videos stop playing after 5 minutes. I have to click on the play button to start the stream again. When I test the internet speed through speedtest.net or speedtest.comcast.net, I get over 40MBPS consistently.
3. The router doesnt recogonize 3TB or above HDDs on either ports
4. As long as all devices connect to one channel (either 5G or 2.4G), the connectivity speed is excellent. The moment a device connects to the other channel, the connection speed fluctuates a lot on both.

My customer is looking at using routers in DMVPN remote locations as DNS servers. He would like to be able to estimate how much memory the DNS cache will consume before going into production. I know you can get cache information when it's running, but he wants to plan ahead.I couldn't find any reports in Cisco or on the web of DNS caching causing memory issues, so I don't think he has much to worry about, but any rule of thumb as to how much memory each cache entry consumes would be useful. Or is there a protection mechanism to limit cache memory size in IOS ? The routers will be 877s and/or 1900-series.

We are facing network heavy and slow performance at one of our remote site, we are using Cisco2800 series router with same IOS on either of the sites.Our WAN network is running on BGP with EIGRP configured and tunnels were configured on either of the sites. As part of the testing I have removed the tunnel to see the performance was ok from Head office to remote branch and the WAN network is getting heavy and slow down when we put the tunnel back in hub and spoke.

I have a very special usecase with migrating devices from LMSv2.6 to v4.1 using DCR bulk import that was maintained manualy, not by discovering.The special thing is each device has its own SNMP-community and its about 1500 devices.RME discovery works fine, but I get the devices not discovered by DCR (CSDiscovery), because I need a minimal DCR discovery configration containing Seed and SNMP-settings. So I activated DCR as seed, but cant skip SNMP settings without an entry. But in this case I would need 1500 SNMP-lines that would be very unhandy. is in CSDiscovery-Settings a possibility to can leave SNMP settings untouched so it takes the credentials from the DCR, to can start DCR discovery?

I'm looking to configure a DMVPN spoke with a Site to Site VPN Connection to a different destination than the DMVPN. I'm using a Cisco 2800 router. When I add the crytpo map to the outside interface for the Site to Site VPN. The DMVPN drops. Is there something I could be missing? The Tunnel interface for the DMVPN has the shared optioin applied to the tunnel protect ipsec profile.

I need to Upgrade my NCS to version 1.1.0.58. Actually my NCS is in the version 1.0.1.4 and i have a lot of templates configured and 1500 Access Points applied.
I have 5 WLCs and will do too the upgrade in the WLCs to version 7.2.130.0.
Will I lose some configuration with these upgrades ? Because the version 1.1.0.58 has more features than version 1.0.1.4 in the NCS and the WLC was adjusted some bugs.
The configurations that i has in the NCS version 1.0.1.4 is H-REAP and in the version 1.1.0.58 will be the FlexConnect, theoretically is the same, but i don't know if the configuration is the same in the two versions.
Can i do a downgrade in the NCS from version 1.1.0.58 to 1.0.1.4 if i have problems ? I was looking for a document who show how can i do this, but i didn't find nothing about.

I would like to connect my playstation 3 to the internet from my laptop which is connected to a guest network (college dorm: I don't have access to a network key - I use my student ID and password at the launch of the browser to access the internet). Is there any way to do this? I have a Dell inspiron 1500 with Windows 7. Basically, what I would like to do is support my ps3 internet connection using my guest network connection from my laptop by running an ethernet cable from the laptop to my playstation.

I am unable to install the driver for my wireless device on my Dell Vostro 1500 laptop running Windows XP Professional. The laptop originally came with Windows Vista Basic edition. I have tried installing the driver for Windows XP from the original drivers CD that came with the laptop and also by downloading it from Dell's Web site. The driver program installs without giving an error, but after installation the device remains nonfunctional and the Device Manager shows no information about the wireless hardware.
My system spec's are as follows:
- Model: Dell Vostro 1500
- Operating System : Windows XP Professional
- Processor : Intel Core 2 Duo 2.2GHz
- Main memory: 2 GB
- Video card : Mobile Intel(R) 965 Express Chipset Family

Here's the current configuration in our organization (which I believe is incorrect):We have a number of Cisco 1500 series AP's (22 in total), that are mounted outdoors to provide seamless WiFi coverage over a large area. Each AP however has its own physical ethernet connection back to the WLC (All the AP's are marked as Root AP's). They are all broadcasting the same SSID. We have tried to stagger the channel selection but because there are only three non-overlapping channels to choose from, and in some areas the density of AP's is quite high, there is multiple places of channel interference. With this configuration we experience 100-150 disconnects from clients every day. (Our clients are mobile so they move throughout the coverage area constantly).
My idea is to switch the AP's to the same channel thereby forming a wireless mesh, use the built in functionality of the 1500 series to use 802.11a as the backhaul, designate one or two AP's as root AP's and wire them back to the WLC. Thereby forming a WiFi mesh, which if I'm not mistaken is the point of the 1500 series in the first place!
I am however completely new at WiFi networks and wondering if I am simply mistaken in what I believe my proposed changes will enable, or if there is a better way to tackle the WiFi topology.

I have the same machine, same problems. After a reformat, WindowsXP would not reload drivers (from the OEM software provided by DELL). I reinstalled (in order) with a fair amount of difficulty got them all to load EXCEPT for the network adapter. I've download the adapter software AND driver; still no luck. Still working on this bugaboo. Incidentally, what saved me with the other drivers (yellow question marks on Base System Device controller, ethernet, PCI, SM Bus, etc) is that I had run a Belarc Advisor utility printout prior to the reformat. So now I at least had something to compare the before and after reformat with.

I have a Inspiron 9400/E1705 laptop with the Dell Wireless 1500 802.11n WLan card when I try to use the utility I get an error message that the internal settings are bad and to restart the computer to fix. It does not fix this. I am currently using the windows wireless to control the card. Is there a way to fix this, It used to work fine just when I downloaded the R151519 update now even when I use a previous update I still get this error. The driver is Broadcom dated 10/12/2006 version 4.100.15.5

got an old Dell Vostro 1500.
(BTW, I saw in the specs of the 1500 that it has Dual Core proccessor, but his is Centerino. How come?)
I formated his computer due to slow-speed among other problems, and did clean install of Win XP Pro.
Now I d/led all the drivers from Dell's site regarding the Vostro 1500, and installed them.
My problem is: Windows doesn't recognize a wireless adapter on the laptop.
Network Connections has only 1394 and LAN options.
In the 'Device Manager' I've got a question mark on "Network Controller" and on "SM channel".
I've tried to manually install Dell Wireless driver - no success.
Tried to set the laptop to ignore the Wireless switch through the BIOS - still havn't got any sign of Wireless adapter in Windows.
BTW - in the BIOS menu - I see "Dell Wireless" under "Wireless" property.
