Cisco :: DMVPN With OSPF Area Router Limit And Per-area Limit?
Oct 31, 2012
need to know the OSPF best design. I have a customer currently running their OSPF only in two area. Area 0 is provider reside and area 1 reside 700 hundred over of router including HQ router and remote branch router connecting to metro-E 10Mbps networks. Is this design have any weakness? Area 1 about 800 hundred router reside in, the HQ model is cisco router 7200 and remote end is cisco router 1841.Let's say they want a solution, for 3G remote router connect back to the HQ using Lease line with a fixed IP. Using DMVPN and OSPF communicating back to HQ. What should we aware when designing and implementing for the OSPF best practice. They have 700 hundred over remote branch need to terminate back to their HQ. I read cisco recommend an area should not be more than 50 router and per-area no more than 28 area.

When you configure an ABR to inject a summary route into an area, what are the circumstances under which the ABR will inject the summary? I.e., since it's not a set of specific subnets learned directly from other OSPF routers, does the summary get injected regardless of what's in the routing table of the ABR?
I would imagine this could cause problems in a situation where there is an ABR injecting a large summary into an NSSA that also has a backup path over the Internet (IPsec tunnel or something). For example, if the area 0 routers from which the ABR receives routes went down, the ABR would continue to inject the summary route into the NSSA thus tricking those routers into sending traffic to the ABR rather than over the backup link.
I can't imagine any other way an ABR would decide when it's suitable to inject the summary though.

We are cutting over from 6500 IOS to Nexus 7000 and have hit "Maximum ospf feature instance limit reached." as we configured up the 7 existing ospf processes - the limit is 4. These existing processes are for various vrf contexts we have. I see you can run multiple vrf contexts under one process - but how does that work in a mixed environment where the ospf neighbours are still ios 6500s? They still expect to see different ospf process id per vrf.

I am currently experiencing difficulties setting up a Netgear router (WNR834B). The router I had been using previously allowed me to access the internet, but frequently dropped the connection, especially when I connected to it via my laptop. I have the new router set up correctly (I even get a signal from it) but both the desktop computer I set it up through and my laptop cannot access the internet. When I diagnose the connection issue I get the message "The network adapter "Local Area Connection" does not have a valid IP configuration."

"Local Area Connection doesn't have a valid IP configuration", and then we are disconnected from the internet. We both can get back on pretty quickly by using the troubleshoot option on our desktops network button on the taskbar, however we'd like to know how to completely eradicate the disconnects as we both game online. We are using a Telus router which we received around a month ago. My brother is connected wirelessly and I am hardwired in. We are both using Windows 7 with newer PC's (within the past year). Neither of us have a clue about networking so we are totally blanked on what settings to tweak to fix this issue, especially since it's not exclusively wireless or wired-in.

The last few days I had been getting the error that: "Local Area Connection doesn't have a valid IP configuration" whenever I reboot my computer. I have to power cycle the router before I can get back the internet connection. Checked on the web and tried various solutions which did not work. So I tried using various firmwares for the WRT160N V2 like V2.03 Build 7 and Build 9. Still did not work. Finally reverted back to my old and trusted FW2.02 Build 8. And this seemed to improve the situation. However, the error will still appear from time to time though not as frequently.

I am setting up a new E4200 modem, and have not been able to use the wired connection. The Windows 7 diagnositic on all three computers tells me "Local Area Connection, doesn't have a valid IP configuration."Model: E4200v1..I am using a new E4200 router, along with a new SE1500 5-port switch and a new SE2800 8-port switch.I am using a wired network that consists of two desktop computers, a laptop computer, a network printer, three Direct TV recorders, two Roku streaming video players, a BluRay player, and an XBox gaming console.Here is what I have done so far.
1- I can bypass the router to establish a direct wired connection to the cable modem. This works to access the internet. It establishes a new wired connection called Network 2.
2- I can access the internet using the wireless connection to the router. It shows a valid IPv4 address.
3- With all cables in place, all the lights are flashing on the router and on the computers.
4- I had changed cables and swapped cable ends.
5- Using the wireless connection, I can access the router home page (192.168.1.1). It shows valid IP addresses.
The problem is that my old Linksys BEFSR81 stopped working, with the same eror message for the LAN connection, "Local Area Connection, doesn't have a valid IP configuration."How often does the WAN port go bad? On both a five-year old BEFSR81, and a brand new E4200?

I just purchased a 100M fiber line to go with a brand new D-Link DIR-655 router. Before plugging in the router, I tested on my laptop directly from the modem and had great result speeds of 98M/97M. I connected the router, then plugged my laptop to find I was only getting speeds of about 10M/6M. This was true for both wired and wireless connections.
I took a look at the router settings. I turned off QoS, but that didn't work. One thing I did see was the WAN was set to auto. I attempted to change that to 100mbps or to 1000mpbs. However, when I did that my modem light that shows a 100M connection is active turned off and I couldn't get internet. I was only able to get a connection if I left that on auto. Is there a setting somewhere that is limiting my bandwidth from the router?I reset the router twice and checked to find I had the latest firmware. Is there something that I am missing? I have always been a Linksys fan, but wanted to see how D-Link is.

I was wondering if theres a program or something that I could use for my router to limit the bandwidth that it gives on wifi? I currently have about a 20down/2up connection from time warner with a linksys E1200 router.
I just want to limit the wifi speeds to about 70% because recently someone moved in that does a lot of downloads and makes my games go from 40 ping to 300+ and also my phone is through the internet, which becomes unusable.
just some simple setting to set the max wifi data to 13megabits/s down 1mbit up or something.

I apologize in advance if this is a novice inquiry, but our company just switched from Point-to-Point T1's to Metro Ethernet.
On one point-to-point, from our main office to one of our high profile locations, we had two bonded T1's. Now this site has a 3 Mbps Metro-E link, but it's being over-saturated. I don't know what type of QOS implementation our T1 provider had, but it prevented flooding. Now, I'm getting horrendous latency as the office peak hours approach since there is no QOS on the mesh by our Metro-E providers.
Ultimately, my question is: what's the best way to set a Fast Ethernet port on a Cisco 1800 series router to limit all bandwidth to 3 Mbps? At the moment, I don't have a preference in which traffic takes priority. I tried the rate-limit command, along with a speed calculator I found online, but that slowed the network down immensely.

I have a Dell desktop with Windows XP Home Edition. I recently restored the computer to factory settings and when I tried connecting to the internet the Local Area Connection wasn't showing in My Network Places. I have been searching through other forums and tried the things that they suggested but nothing worked. I am trying to connect to an AT&T U-verse 2Wire router through a wired connection. I tried connecting both wirelessly and wired to another computer and everything worked fine. I checked the Device Manager and there is an ! mark next to the Ethernet Controller. The properties say that the drivers for that device aren't installed. And of course I can't install them since I can't access the internet. Other forums suggested that I check the network adapters option in Device Manager but that isn't available in the device manager.

I'm at task 6
Am I wrong but the only way to filter external routes - type 5 - is with a stub area, and area 0 can't be a stub? As far as I know OSPF can't filter on the route tag, so should I be filtering with a route-map?

We have some point-to-point sites linked with our HO with 10-30mbps speed. We have provided DID telephone lines to these sites as well.
We want to limit the bandwidth with 1mb bandwidth only and also make sure that the voice traffic (DID telephone lines) gets the priority over all other traffic even if they are utilitizing the 1mb link completely. We have some Cisco 1841 routers that we are planning to configure on the main uplink on each of these sites. how to give the priority to the voice traffic yet limiting the bandwidth to 1mb.

My error message states that "Windows could not finish repairing the problem because the following action cannot be completed: Registering with DNS".I have no internet connection on my HP PC, which is why I am typing this on my laptop.On the HP I am running windows xp with sp3.I connect to a cable modem provide by Time Warner.This problem started yesterday, so I have been utilizing both computers with one internet connection, or plugging and unplugging the cat5 cable.I have run Microsoft Essential Full scan, as well as Malwarebytes's Anti-malware.Now I ran both of those in Safe mode, and picked up no bugs. I have Avast as my antivirus software, and the message I receive on that is that "Avast will not be able tp protect mail/news (error 10050). I am unable to turn on the web shields for Avast.I have manually entered the IP addresses into my HP from my laptop, all the way thru DNS servers.It still won't connect.I tried using the Internet explorer diagnostic tool, and it came back and said that I have a winsock issue.

1. Internet works ok, everything is fine, but then it stops working for no reason.
2. I open Network and Sharing Center, and do diagnostics. They come up with result: "the default gateway is not available". Nothing works. But Local Area Connection and Network Controller are both enabled.
3. I have to restart computer for the internet to work again. However, it doesn't restart: it hangs forever in "shutting down" screen, and nothing happens. Probably because computer is still trying to connect to the internet (?)
4. After forced restart, internet doesn't work, but if I run diagnostics again, they come up with result: "The Local Area Connection adapter is disabled", and fixes it automatically. Internet works then.

My internet is working fine, but my Ethernet cannot get a connection. On my Ethernet Local Area Connection it says status is: Limited or no connectivity i am running an Ethernet cable from my xbox 360 to the Ethernet adapter slot at the back of my computer, no wireless or anything. And as i say the internet works fine though i cant get any connectivity out of the Ethernet adapter.This used to work fine two weeks ago, now it refuses to work i recently moved and so i disconnected my pc nothing broke and all it did was sit around in a safe place before the move EVERYTHING worked fine, On my xbox the display says:Network adapter - wired IP address - failed?i'm running windows xp sp 2?

I have just recently installed a new router for my home and the ethernet connection stopped showing up. It instead said "no connections available". I figured the onboard network adapter gave out because of the orange light it gave off and bought a NetGear GA311 network adapter. I installed it and updated it, but the connection still says there are none available.
