MPLS using VPN and ISIS

I 'am looking for a good description for MPLS/VPN we want use ISIS and BGP as Routing Protocols.
What we also need is a detailed description of a Configurtaion example.
Can provide such informations.

Detailed information can be found at (whithin these URLs, there are several links to undesrtand and configure MPLS/VPN with ISIS or BGP):

I am using VPN, and Firefox is loading the page. Before I reinstall the new version, the VPN was working okay. Whta happened, what I am supposed to do?
I have to use the VPN to acess the site because of the limitatation , and it was working okay. When I do turn off the VPN, then the sites will open, but if I activate the VPN, then site will load for ever, but they won't load.
Please advise me what to do?

You might try using the add-on 'NoSquint' which allows numerous zoom options specific to each page you visit & keeps your settings - https://addons.mozilla.org/en-US/firefox/addon/nosquint/
If you want to go back to 3.6x, you will find it here:

In most cases you can simply "upgrade" (meaning downgrade) directly from the installation. It would be a good idea to save your passwords & bookmarks just to be on the safe side.

Configuring Admin Util to allow me to use VPN AND surf the rest of the net

I am having a problem when I connect to my work network via VPN. When I do, I can no longer connect to the rest of the Internet. I was able to do this until I started using an Express (so it has been allowed by my work network).
Here's my setup: Express is connected via Ethernet to my Verizon Fios modem. When I connect my computer directly to the Verizon modem all works fine. I have been advised that what's happening is that my Airport Express is creating a behind-the-device network that has the same exact IP address space as your office's network (when I'm connected to it via VPN).
To fix this I've been told to "Go into the Airport administration app, click on the "Internet" icon at the top of the configuration pane for your AE, then click on the "DHCP" tab, and look at what the "DHCP Range" pull-down menu is currently set to. After writing this down (in case you need to go back to it), change to one of the other options -- e.g., if it's currently set to "10.0.", change to "192.168." or "172.16". That should be enough to move you completely out of the space that your VPN is using. Save the changes, let your AE reboot, and try using the VPN and the internet at the same time again."
The problem is that the advisor is using Airport Admin Util version 5.x and I am using version 4.2. The screen he suggests is not where his is in his version. Could someone advise me of how I can do this via 4.2?

Reset your iPad and see if that fixes this.
Reset the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider if it appears on the screen - let go of the buttons. Let the iPad start up.

Connect to workplace network - Using VPN and having trouble mapping to path

I need to connect to a couple of drives on my workplace. I work remotely. I was able to create a VPN connection (via System Preferences > Network) with the info they provided. I connect and it shows the connection as being successful.
However, I haven't been able to connect to a couple of directories. The paths they provided look something like this:
\\ServerName\DirectoryName
\\ServerName\users\UserName
I tried the Go > Connect to server and typed it like this:
smb://servername/directoryname
But I haven't been able to connect. I get an error window that says:
Connection Failed.
The server may not exist or it is not operational at this time. Check the server name or IP address and your network connection and try again.
What am I doing wrong?

This is a very strange one, I had same issues and was able to fix it. Let’s see if the fix works for you.
If SMB enabled on your Server.
What I did was to change connection to smb://Server IP/ShareName
Then connect and it all worked fine. The next time I connected to the Server I just connected the normal way i.e. just ServerName and ShareName using AFP and it all works fine now.
See if this helps you.

Performance end to end testing and comparison between MPLS VPN and VPLS VPN

Hi,
I am student of MSc Network Security and as for my project which is " Comparison between MPLS L3 VPN and VPLS VPN, performance monitoring by end to end testing " I have heard a lot of buzz about VPLS as becoming NGN, I wanted to exppore that and produce a comparison report of which technology is better. To accomplish this I am using GNS3, with respect to the MPLS L3 VPN lab setup that is not a problem but I am stuck at the VPLS part how to setup that ? I have searched but unable to find any cost effective mean, even it is not possible in the university lab as we dont have 7600 series
I would appreciate any support, guidence, advice.
Thanks
Shahbaz

Hi Shahbaz,
I am not completely sure I understand your request.
MPLS VPN and VPLS are 2 technologies meant to address to different needs, L3 VPN as opposed as L2 VPN. Not completely sure how you would compare them in terms of performance. Would you compare the performance of a F1 racing car with a Rally racing car?
From the ISP point of view there is little difference (if we don't want to consider the specific inherent peculiarities of each technology) , as in the very basic scenarios we can boil down to the following basic operations for both:
Ingress PE impose 2 labels (at least)
Core Ps swap top most MPLS label
Egress PE removes last label exposing underlying packet or frame.
So whether the LSRs deal with underlying L2 frames or L3 IP packets there is no real difference in terms of performance (actually the P routers don't even notice any difference).
About simulators, I am not aware of anyone able to simulate a L2 VPN (AtoM or VPLS).

Using VPN on ipod touch and trying to connect to my computer wirelessly

OK HI everyone I'm new to this forum thing here in apple this is my first thread so please don't flame me.
(It happens allot on other forums, not to me but to other newbies)
anyway focusing on the task at hand
so im trying to find a way to connect to the internet on my ipod NOT using a wifi connection, I noticed under GENERAL settings when you go under NETWORK there is WI-FI or VPN and im trying to see what's all that about
and i also have usb broadband modem and I found some Server IPV address or something like that under my modem Status so I'm trying to see if i can somehow work with any of these things to connect to the internet on my ipod
BTW i have an ipod 3rd Gen and a Cricket Modem and Windows Vista OS

Sorry, but the only way that you can connect your iPod to the internet is via WiFi. To use VPN, you must be connected, again via WiFi, to the internet. VPN (used mostly by businesses) allows you a super secure way to access internal networks via a public network (the web).
You must have a wireless router to connect to allow WiFi. An ordinary router isn't going to be able to do it. See this article: http://computer.howstuffworks.com/wireless-network.htm for some basics on wireless networking.

How do I save changes to a document using VPN, Safari and Excel Mac?

Hi. I'm using VPN to reach documents on a server. I want to make changes to an excel document and save the changes back to the server. I'm using Safari and Excel Mac. When I'm finish making changes I tried to save the document back to the server. The changes was not saved? When I tried it on a PC it works well. Why can't I save the changes? Hope somebody can help me :-) Thanks a lot. Åke from Norway.

I did this after I wrote this. I have looked at the documentation but I can't find what I am looking for. Is there another way to open a file for viewing that has the full capabilities or using the normal program...one that uses something besides AxAcroPDFLib.AxAcroPDF. The sample that did have a view used AxAcroPDFLib.AxAcroPDF so it wasn't helpful. All I need is normal program functionality of adobe standard or profession within the application. The users have a full version installed on their PC.
Thanks again.

When I use VPN on iPad 2 ,it disconnects alot and frequently,plz help me

Hi friends,when I use VPN on my new iPad 2 ,the VPN disconnects a lot and frequently in short periods,please help me,is there any solution???

You should provide more detailed info, like who is your VPN provider, what VPN protocol (PPTP, L2TP, IPSec,) whether you're on home Wi-Fi, public Wi-Fi, 3G and if public Wi-Fi or 3G, then geographical location. (i.e.: Starbucks on 5th & Broadstreet, Detroit.)

L3 vpn and VPLS on same SVI.

Hi,
Can anyone help me with this query?
I am trying to connect a CE router with two redundant links to two seperate PEs. I need spanning tree to be run between the PEs for the resilence and failover so was thinking VPLS, but also need the CE to connect to a L3 vpn.
Does anyone know if it is possible to have a vlan (SVI) in a VPLS instance and a L3 MPLS vpn?
Thanks
Wai-Lun

Hello Wai,
I may be wrong but I don't think you can at the same time over a single SVI to offer L3 VPN and L2 VPN services.
However, I would suggest to divide your links/requirements: the two CE-PE1 and CE-PE2 links will be VRF access links from the PE point of view and you can use a dynamic protocol.
Routing protols can provide all the failover and redundancy you are looking for.
The PE Routers will be interconnected via MPLS backbone links.
If you miss your own backbone infrastructure you can use CSC (Carrier Supporting Carrier) or lease simple EoMPLS /VPLS links from a provider (this may need some thoughts about MTU)
hope to help
best regards

MPLS using ripv2 bridge

hi all,
here my scanerio,
rightnow we are using the wireless bridge between the sites , so the network is same on both ends all the servers and ip telephony in one site.(SITE A)
now we are got from ISP layer 3 MPLS link using ripv2 routing.
is it possible to make the MPLS link also like wireless brige?
or
the networks on both ends should be different. if it is , how to route all the traffic through the MPLS to other side .( like internet and VOICE).
here the network details
172.16.0.0/16 -- my site A network which all devices are there
my MPLS IP -site A 172.16.1.61/30
connected with cisco router one interface as 172.16.1.55/16 and MPLS interface as 172.16.1.62/30
and Site B -- 172.16.1.57/30
connected with cisco router one interface as 172.16.1.56/16 and MPLS interface 172.16.1.58/30
this what i have done it but not tested.( i am sure this is not correct)
will this work or we need to have seperate networks on both end?
thanks
cyril

Hello Cyril,
my understanding is that you have bought a single L3 VPN service with an access link in site A and one link in site B.
The SP network is in the middle and does not allow to achieve your objective, because it makes a choice of single best route, and it propagates only this.
Inside Site A, PBR policy based routing based on source address can be used on CE device (the router connected to the MPLS cloud) to send traffic to RA or RB depending on the source address of traffic originated at SiteB
example:
I make the assumption that you have a third router at site A RC that acts as CE node of site A.
I also assume a common LAN between RA,RB and RC inside siteA.
The following are on this CE node.
access-list 111 deny ip 192.168.1.0 0.0.0.255 172.16.0.0 0.0.255.255
access-list 111 deny ip 192.168.1.0 0.0.0.255 10.1.1.0 0.0.0.255.
access-list 111 permit ip 192.168.1.0 0.0.0.255 any
access-list 112 deny ip 192.168.2.0 0.0.0.255 172.16.0.0 0.0.255.255
access-list 112 deny ip 192.168.2.0 0.0.0.255 10.1.1.0 0.0.0.255.
access-list 112 permit ip 192.168.2.0 0.0.0.255 any
route-map PBR-siteB permit 10
match ip address 111
set ip next-hop
route-map PBR-siteB permit 20
match ip address 112
set ip next-hop
interfaces fas0/0
desc to SP MPLS network
ip policy route-map PBR-siteB
+
RIP configuration towards SP
the first two lines of ACL 111 are for allowing inter site routing, only traffic with a destination outside siteA have to be processed by PBR.
warning: this is just an example to show the logic of PBR .and I haven't checked all the commands
PBR works inbound on traffic received on CE router on the MPLS L3 VPN access link
Edit:
RA and RB will also need a NAT configuration.
Hope to help
Giuseppe

MPLS L2 VPN

Hi,
What is L2 MPLS VPN & how to configure it end-to-end, What are the diffrence with L3 VPN
What is vrflite & what is the pros/cons of the same
Br/Subhojit

In a MPLS L3 VPN the service provider carries the route for the customer. The network is not transparent meaning that layer 2 traffic such as broadcast and control plane traffic like CDP/LACP/STP etc is not carried for the customer.
There are different L2 VPNS such as Ethernet over MPLS (EoMPLS) and Virtual Private LAN Service (VPLS).
EoMPLS is a point to point layer 2 service which does no MAC learning and it is transparent to the customer meaning that the customer can connect two switches together over the "cloud".
VPLS is a multipoint to multipoint technology. Essentially to the customer the provider network looks like a big switch. Several sites can be connected together and traffic here is also transparent.
Because these are layer 2 services the customer would be responsible themselves for providing routing in the network.
VRF lite is a form of L3 VPN but it's not running MPLS. Instead it uses VLANs to separate customer traffic. The cons are that it requires more configuration, is less scalable and needs peering in multiple VRFs compared to just peering in the VPNv4 address family.

How do I use VPN for file sharing?

Hi folks, hope you can help.
I need to find a method for file sharing between my company's two offices, which are not only in different countries but also use both PCs and Macs. I think setting up a VPN is the way forward.
My file server is a Mac Mini running the standard client version of OS 10.5.4, with a static IP, 217.xxx.xxx.xxx. I need the PCs and Macs to access its resources. It is set up to share its files using FTP, AFP and SMB. It is running the application iVPN Server, which I understand is a GUI that makes the built-in OS X VPN Server function available to the client edition of OS X.
I am currently overseas and can connect to the Mac Mini over VPN. The problem is that I cannot seem to access the Mac Mini's files - I don't know what to do having established the VPN connection. I was half-expecting it to show up in the Finder under Shared or something.
The Mac Mini has a local IP of 10.0.1.20, but the VPN Server is issuing an IP to all clients in the range 192.168.2.200 and beyond. Is this where I'm going wrong?
Should the Mac Mini VPN Server also connect to itself, using VPN, as a client?
I'm really stuck, all help is very much appreciated. Thank you!

Thanks for prompt reply Topher..
I am familiar with the Connect to Server window, but I am not sure which IP I should be using. Assuming no VPN connection for the moment, and assuming I'm on a remote network, I can connect to the User's documents folder on the Mac Mini already by typing afp://[username:password]@[static WAN ip]/Documents
However, I need to ensure that SMB shares work (I know they work when I'm on the local network). So I type smb://[username:password]@[static WAN ip]/Documents but this fails to connect to the User's Documents folder.
To make the SMB shares work I think I have to connect using VPN. So I connect to the Mac Mini via VPN, and my laptop is issued a VPN IP of 192.168.2.200. Of course my laptop also has an IP from my local network. Do I need to rearrange my network order in System Preferences?
So I'm now connected via VPN. However to view the Mac Mini's files, surely it also needs to have an IP issued by the VPN Server? But the Mac Mini is the VPN server. So should I go into its System Preferences and set up a VPN connection to itself?
Now back on the laptop and I want to browse User's Documents folder on the Mac Mini using SMB. I go Connect to Server, and I guess I would type smb://[username:password]@[Mac Mini's VPN IP]/Documents
Am I on the right track? Thanks again...

IpSec VPN and NAT don't work togheter on HP MSR 20 20

Hi People,
I'm getting several issues, let me explain:
I have a Router HP MSR with 2 ethernet interfaces, Eth 0/0 - WAN (186.177.159.98) and Eth 0/1 LAN (192.168.100.0 /24). I have configured a VPN site to site thru the internet, and it works really well. The other site has the subnet 10.10.10.0 and i can reache the network thru the VPN Ipsec. The issue is that the network 192.168.100.0 /24 needs to reach internet with the same public address, so I have set a basic NT configuration, when I put the nat configuration into Eth 0/0 all network 192.168.100.0 can go to internet, but the VPN goes down, when I remove the NAT from Eth 0/0 the VPN goes Up, but the network 192.168.100.0 Can't go to internet.
I'm missing something but i don't know what it is !!!!, See below the configuration.
Can anyone help me qith that, I need to send te traffic with target 10.10.10.0 thru the VPN, and all other traffic to internet, Basically I need that NAT and VPN work fine at same time.
Note: I just have only One public Ip address.

Sorry for the picture and the "bumping"... I have asked in irc in arch and alsa channels and no luck yet... one guy from alsa said I had to wait for the alsa-driver-1.0.24 package (currently I have alsa-driver-1.0.23) but it is weird because the microphone worked some months ago...
