DMVPN Default routes (over internet and over tunnel)

Hello all,
I want to implement a DMVPN (using OSPF) solution in which all routers are connected to the internet and all of then have dynamic IP addresses (except hub). Because of this each router have a default gateway pointing to the ISP IP address.
With this solution I want a spoke to skope topology and I also want all customer internet traffic to go via central site. The problem is that I need a defaut route to reach other spokes and this way traffic to internet via central site does not use the tunnel.
Is there any feature that alow to overcome this situation?
Regards,
João Carvalho

Absolutely. You can do this easily with VRF Lite. Configure a separate VRF for your customer, place the tunnel interface and the customer's VLAN into the VRF and run your OSPF process within the VRF. This allows the router's global routing table to keep a default gateway to the ISP, but lets you define the customer's default gateway as the DMVPN hub. I have a dual-hub DMVPN network with a couple of hundred sites using exactly this approach.

After a week's worth of debugging, I found the issue.
The Java type returned from the call was defined as ArrayList. Changing it to List resolved the problem.
I'm not sure why ArrayList isn't a valid return type, I've been looking at the Adobe docs, and still can't see why this isn't valid. And, why it works in Debug mode and not in Release build is even stranger. Maybe someone can shed some light on the logic here to me.

ASA receiving two default routes to internet via OSPF

I am trying to test something for a client. If I have an ASA that receives two default routes to the internet via OSPF, will it load balance those connections? I have a feeling the answer is 'no.' If that is the case, would the ASA would be at least able use the second internet connection if the primary one becomes saturated?
TIA,
Dan

Yes, I know that the ASA cannot have default routes on multiple interfaces. Both of the default routes are coming into the ASA's outside interface. There would be two routers and the ASA in area 0 for OSPF. The routers would have the default-information originate command in their OSPF configuration to push the default route out to the ASA.

I have just updated my hard drive in my 15" MBP. I then loaded lion over Internet and then restored from my old HD. Now the MBP will not boot! Have I stuffed it?

HI, help! I have just replaced my hard rive in my 15" MBP.I have loaded lion back via Internet . I then restored from my old hard drive. Now the MBP won't boot, where as before I restored it was operating perfectly just with out my data only icloud data. Can I erase, my restore? Will I ever see my data again?

What do you see on the screen when it doesn't boot??
Gray, Blue or White screen at boot, w/spinner/progress bar
or
Folder with question mark issue?
How did you restore from your old hard drive?
Technically all that was needed was to use Migration Assistant on the fresh OS X install to migrate users accounts and programs to the new machine.
You can use a SATA to USB adapter to connect the old drive if you want to go that way and start over with a fresh install again on the new drive.

Unable to connect router to internet and computer at the same time.

I'm not sure where to start, but here goes. We recently got the internet set up at out new house. Of course, the only connection is downstairs and the computer is upstairs. The guys that set the internet up said we needed a wireless router and I said "Ok, cool."
He gave us a router and a receiver and hooked them both up. (I myself know quite a bit about computers but I figured I'd let him do his job.) So we're all set up and I start playing my game and I get a "Windows has a conflict with another computer on this IP" or something like that. I figured I might as well put some security up on this thing. So I go downstairs and hit the SecureEasySetup (SES from now on) button and come back up here and follow all of the steps and it say's that it's not connected. I run back downstairs and looc for the MAC Address and notice that it was not mentioned as one of the selectable routers.
I figured the guy didn't really install the router, just hooked the internet up into it and plugged it in, and that my reciever picked up someone else's from the neighborhood. So I go and get the CD to install and notice that I have to have the router plugged into the computer AND the internet at the same time for installation to complete. Uhh, that could be a problem. Computer upstairs + router and internet cable downstairs = no go.
So here's my question: What can I do about that? I can't have the computer and the internet hooked up to the router at the same time.
Thanks to everyone that replies.

First off... don't use the setup CD.
Configure your router by http(ing) to the IP address, log in, and configure that way. much easier. typically its http://192.168.1.1
username admin
password admin
once you get logged in change that password and Remember it! If you lose it, you'll have to reset to factory defaults.
2nd
Change your SSID. Default is "linksys" you'd be suprised how many people leave the thing as defaults and someone else is using yoru network connection...
3rd
Add security WPA is better than WEP
4th
Now go upstairs and look for your new SSID, connect with your WPA code and you should be set.
5th - Not needed but for info...
If you want to go that far... you can change your DHCP set to something like 10.0.10.x but you'll have to manually change the IP of the router to that subnet as well...

Linksys Wireless Router - Unusable internet and major packet loss

I installed a Linksys Wireless router at my friend's home and the internet connection is nearly unusable. About 1 in every 10 packets are lost between the router and internet modem. I have replaced this router with a 2 brand new routers of the same make and incurred the same problem (new ethernet cables and new power supplies as well). Even if wireless is disabled on the router, the same problem occurs. Interestingly, I tried a basic non-wireless router and there is no problem whatsoever. Any ideas on what could be causing the wireless routers to not work correctly?

First, connect your system up: EUM3005 -- WRT54GS -- computer. And in the computer, temporarily turn off your software firewall. Does this correct your packet loss problem? If not, then power down your system, and proceed with the following tests, and post your results:
Connect your computer directly to your EUM3005 modem. (Do not use the WRT54GS for this test.) Power up your system, and verify that you have a working Internet connection, then do the following:
In the computer, go to "Start" > All Programs > Accessories > Command Prompt.
A black DOS box will appear. Type in "ipconfig /all" (with no quotes), then hit the Enter key. Post all of your results, except post only the first half of your IP address. To copy the results to your post, highlight the data, then use the copy (Ctrl-c) keys and the paste (Ctrl-v) keys.
Next, power down your entire system, then connect the WRT54GS to your EUM3005. Connect your computer to the WRT54GS. Boot up your system. Go into the WRT54GS setup menu (at 192.168.1.1) and ping the EUM3005. Did that work? Next, in the WRT54GS, go to the "Status" tab, "Router" subtab. Look down the page to the area labeled "Internet", then post the following info from the page: "Login type", "IP address", "Subnet mask", "Default Gateway", and "Primary DNS" values, except post only the first half of your IP address.
Is the IP address the same from both tests?

Is there a way to have a Chicken of the vnc type GUI over internet in ARD3?

Hello, to whoever reads this question, thanks in advance if you can help.
My need is this. I regularly use Chicken of the VNC for multiple administration over the internet, but what I like is the possibility to have same IP but Multiple clients with fixed IP (local) behind Firewall, i.e. x.x.x.x:5910 x.x.x.x:5920, x.x.x.x:5930, etc. and i can connect at the same time to the different machines to admin them.
Question: Is there any possibility to have the multiple connections with ARD 3 or even ARD 2 over the internet with same IP?
At one point ARD 3 did work for me like that for about an hour and then it stopped, blocking out 2 of 3 machines in the same IP. I mean, it acutally let me have 2 windows open on the same IP with different ports over internet and was flabbergasted, but then it stopped! when I quitted and restarted, I could do it no more…
I really like ARD, but if I got to manually change the port everytime I log in… yikes…!! I admin 20 machines in 10 different locations, so everytime i gotta log in to machine 'a' then change ports to machine 'b' for 10 locations everyday… well I hope you get the idea.
BTW i tried looking all over the forum, but could not find this info specifically.
PS thank you for your time

I, too, was a bit bummed out by the lack of this feature. I wondered if ARD 3 had some sort of mode Apple themselves used "silently".
There IS a way to make it work, however -- via VPN. I discovered that once I used VPN into my company's intranet, ARD 3's scanner could see EVERY Mac in the company.
Setting up a VPN nowadays is pretty simple -- many routers handle the support for you. OS X's Internet Connect feature makes it trivial to connect to the VPN, once it is properly set up from the inside of the company.

Is there a way to connect to my Time Capsule over internet from an iPad

Hi,
Could anybody please help me configure how to connect to my Time Capsule 3TB over internet from my iPad.
I would like to use it as Cloud station over internet.
I was able to connect from my Mac on both "over internet and from my local network" using "Back to My Mac"
I was able to conncet also from my iPad from my local network.
I bought some file browser Apps which enable iPad to connect as "afp, smb" but I could'nt manage to make it work?
I made all the setting required: Enabling NAT Port Mapping, File Sharing, Sharing Disk over WAN, but without success?!
Shouldn't Apple includes and supports iPad to make such connection like "Back to My Mac" protocol.
I believe that Time Capsule is a great product, but I think Apple should consider more of software compatibilities.
Thanks,,

Thanks Bob,
I already tried FileBrowser and I did all the steps as per the instruction on their webpage, but alwasy give error message.
Could it be that "smb" protocol blocked by my internet provider.
I am connecting to internet using DHCP.
Many thanks

IP SLA Default Route state down to much

Hello,
I am attempting to use IP SLA trackers to dynamically set the default route going out over a DSL connection. if the sla trackers are down the default route learned from the WAN will take over, but normally we want to send internet/default route bound traffic out over the DSL connection.
ip route 208.67.220.220 255.255.255.255 1.2.3.4
ip route 208.67.222.222 255.255.255.255 1.2.3.4
ip route 0.0.0.0 0.0.0.0 1.2.3.4 track 3
track 1 ip sla 1
delay down 60 up 60
track 2 ip sla 2
delay down 60 up 60
track 3 list boolean or
object 1
object 2
ip sla 1
icmp-echo 208.67.222.222 source-ip 1.2.3.5
threshold 1000
frequency 10
ip sla schedule 1 life forever start-time now
ip sla 2
icmp-echo 208.67.220.220 source-ip 1.2.3.5
threshold 1000
frequency 10
ip sla schedule 2 life forever start-time now
the issue we are having is if the SLA threshold is breached, it immediately sends the trackers into a delay down state. the tracker delays down for 60 seconds, then very quickly comes back up. What we want to accomplish is only if the sla tracker has breached the threshold or is down for 60 seconds, then put the tracker into a down state.
Thanks.

The configuration seems to be correct: IP SLA change as soon as the icmp fail but the tracker delay should ensure the it changes its state after 60seconds of icmp failure. Do you experience a different behaviour ?
What I'm worried about is that, after the default router through the WAN is in routing table, the ip sla ping will be successful and therefore the static route
ip route 0.0.0.0 0.0.0.0 71.32.39.46 track 3
will be used but, at that point, which is the path to 71.32.39.46 ?
Another thing is that, in case of DSL link failure, this configuration will not automatically revert to WAN link because 71.32.39.46 will be still up and running, isn't it ?
Let me know,

How to set the default route on a RVS4000 to point to a gateway in the LAN

Hi
The dialog in the RVS4000 for static routes does not allow to set the default route to point to a gateway in the LAN. Clearly this is either a bug or a feature of the web-interface and not a restriction of the box, which runs some kind of linux. So my question is there a way around this problem rather then defining routes to n-class A networks to cover the internet? Like a terminal access to set the default route?
Thanks and cheers
Frank

Hi David
Thanks for your reply. I did already the first part and it seems that I presumed wrongly that the RVS4000 can be used as a layer 3 switch, instead it is only a 1-port gateway. Not that there is a technical limitation from the hardware or the OS of the box. It does layer 3 routing e.g. for its VLAN's. The only point to stop it from having the capability which I expect from something called router is to set its default route to the right gateway independant which port might be connected. The reason why I want a LAN port pointing to the gateway and do not use the WAN port without firewall is of course the VLAN capability of the LAN ports. The idea of the RVS is to bundle two nets, including the one where the gateway is on, and send it to a WAP4410N box, which nicely makes them wireless with different SSID's. Actually I have two ports connetced to the core network, if I am forced to have only the WAN port connected to the core, due to this artificial limitation, I would have to reconfigure a bit. Therefore I try to find an easier solution setting the route by "hand".
Cheers Frank

CSS advertise OSPF default route?

I have a CSS in one armed mode sitting between the Internet Edge router and PIX firewall.
The edge router is getting a default route from BGP and distributes that into the Firewall via OSPF.
The firewall sees the Edge router as the default gateway from the distributed route.
Would it be possible to have the CSS (through OSPF) get the default route from the Edge router and advertise it to the Firewall?
The goal is to have the Firewall use the CSS as it's default gateway, rather than the Edge router, but it needs to be a dynamic route.
In turn the edge router would pass traffic through the CSS to the firewall.
The CSS would be an intermidiate hop between the router and firewall.
Is this something that the CSS is capable of doing?
And from a design perspective, it is something that could be an issue?

Thanks,
I did see that document and played with it some last night.
I think it should work too, but was not sure if it was not reccomended by Cisco or not.
I have seen they they do not reccomend OSPF or RIP configurations, but I am only concerned with the default route and this would maybe solve the problem of any potential asymetric traffic flow.

IPv6 default route

Hi,
I had border router, ipv6 BGP peering to upstream ISP and it learned about 5K of IPv6 BGP routes.
Internally I had another router iBGP peering with border router. But I do not want this internal router learned full ipv6 routes.
I would like it learn ipv6 route from 1st level upstream only and default route.
Question is what is IPv6 default route to internet ? for ipv4 it is 0.0.0.0/0
It is ::/0 ? or 2001::/23
Regards

The IPv6 equivalent to IPv4's 0.0.0.0/0 is ::/0
So, answering to your question: default route for IPv6 is ::/0
Cheers, Gustavo

ISIS v6 Default Route

I have 3 hosts A, B and C. A connects to B and B connects to C. A and C have no direct connection. A and C have a default route for BGP and ISIS (done with default originate command fo ISIS). A and C have local firewalls with A being primary. They are all IBGP neighbors. I need to raise default route metric of ISIS so C will use its BGP route instead.
v4 IGP is OSPF which i just mark up with a route map, I don't see similar options for ISIS.

My local network is 192.168.139.0/24 and my gateway is 192.168.139.1
Not according to that netstat output.
Nowhere does 192.168.139 appear anywhere in the list. In fact, that's telling me that 169.254.x.x is the subnet attached to your ethernet port.
That typically happens because your machine didn't get a response from the DHCP server. This could be due to a flaky DHCP server (e.g. its unreliable, slow, or otherwise not responding), or because your DHCP server has run out of addresses to issue to clients.
It could also be caused by poor cabling between you and the DHCP server.
Either way it sounds like your DHCP lease isn't getting renewed, and that's where I'd focus.

My airport extreme (generation 5) was set up using wifi and has worked flawlessly (on macbook pro 2 iphones and window 7 HP pc)until recently. I have reset to factory defaults over and over but still cannot get on the internet. Any suggestions?

My airport extreme (generation 5) was set up using wifi and has worked flawlessly (on macbook pro 2 iphones and window 7 HP pc)until recently. I have reset to factory defaults over and over but still cannot get on the internet. However I can then take my DSL cord and insert it in a different Ethernet port other than the WAN port and I can get internet on my Mac and iphones but only wifi on my husband's PC. I hate to spend another $179 if this is just something I'm doing wrong. Please help

I'm having a bit of trouble confirming that the ZyXEL is a combination modem & wireless-N router. If it is, then you really won't get any advantages of using the 802.11g AirPort.
If the range of your ZyXEL is limited, you may find that doing either or both of the following will help: 1) Move the ZyXEL so that it is higher vs. lower in the room, that is away from any closed areas or placed in a metal cabinet, and 2) Changing radio channels. The latter is especially important in you live in an area where there are a number of competing Wi-Fi.
A good utility to find out, is iStumbler. You would use this to find these other Wi-Fi and find which have the strongest signal value. Those that do, you would also want to note which channel they are operating on, and then, change yours to one that is at least 3-5 channels away. So, for example, if you find strong ones on channels 1 & 6, change yours to 11.
