L3 VPN and MPLS core
Hi all,
1) I am new to MPLS and trying to configure a scenario in a non production environment. Is it possible to have L3 VPN's without using BGP in MPLS core network? For some reason I am more inclined to use RIPv2, EIGRP or OSPF in the core.
2) Is it possible to use 2600 series router as PE?
Thanks in advance.
hi SHAH
to add to the nice cooments in the discussion
the BGP used with mpls and L3 VPN called MP-BGP
the VPN in with VRFs, RD and RT each one add to the ip packet an identifier to distingush the packet with the provider network from other packet and make it uniqe to pass these identifiers from router to router especiallt from PE router to PE router u need the BGP (MP-BGP)
hope this helpful

Hi,
I want to know the answers for the following failure scenario
1.Unknown LSP connectivity problem: LSP connectivity problem ,Data plan issue, or unknown cause
2.Distributed LFIB table discrepancy: There is a discrepancy in the LFIB table between the route processor and line cards
3.Distributed LFIB table discrepancy: There is a discrepancy in the FIB table between the route processor and line cardshello dear mohisaxe,
so sorry for the late response, yes we plan to use them on separate ports and both CE and use the same line card as both customer and MPLS core facing.
just another quick question i have here:
1- as Mr. Xander's information, MOD80 line card has 2 typhoons each of them can accommodate 32K PPPOE sessions with limitation of 64K limit per line card.
2- as we have MOD160 line card with 4 typhoons, do we have the same limitation as above?
thanks for your support :) -
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
ShahbazHi 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).

How is load-balancing achieved in MPLS L3 vpns and equal cost multiple links exist to reach egress PE along with per-destination load-balancing enabled on interfaces.
I have tried to simulate the network below
Ingress PE--->P1--->>P2--->Egress PE
Multiple equal cost links exist between P1 and P2, cisco platform,LDP, IGP-ospf being used.Hi,
Destination based load balancing in MPLS L3VPNs can be categorized into two scenarios:
1) multiple pathes between two PE routers
2) multiple access links to a single CE or site
Your question as I understand it was about the first scenario. So let me first quickly review how customer traffic is forwarded between VRFs on two different PE routers.
The VRF routing table will have BGP entries for the routes learned from the remote PE usually with next hop addresses being the remote PE loopback IP used for PE-to-PE BGP peering.
The traffic will be forwarded across P routers using the label for the BGP next hop.
Thus the load balancing accross the MPLS core in a first step is decided by the IGP, which has to insert several equal cost pathes into the global routing table for the BGP next hop networks (PE loopbacks).
Side note: MPLS traffic engineering in the core would allow for unequal cost load balancing.
The decision, which labeled packet to send across which path in the core is done by CEF using a hash algorithm. To achieve the same load balancing as with unlabeled IP traffic, a Cisco MPLS enabled router will look for the bottom label - the one with bottom-of-stack bit set to 1 - and try to determine, if the transported packet behind the bottom label is IP. If so, the hash is calculated for the customer IP header like for normal IP traffic. This ensures all traffic for a certain customer destination will always go through the same path. No unwanted packet reordering will occur.
Be aware, that the customer IP packet header will only be used for CEF hash calculation, no IP lookup will be performed, as core routers in MPLS L3VPNs do not have any knowledge about customer addresses.
As a side note: if the traffic transported is not IP (e.g. Ethernet over MPLS), the bottom label will be used for the CEF load balancing (e.g. the VC label).
For the second scenario - CE load balancing with multihomed CE/sites - it is first required to have two equal cost entries in the VRF routing tables. The difference will be the two different PE BGP next hop addresses. The first load balancing decision is the performed by CEF based on the IP packet received by the CE and the VRF routing table entries. Once CEF decided, which VRF entry to use, the required BGP next hop label (and the VPN label) is applied and the packet is transported across the MPLS core. load balancing there is done as described above.
Hope this helps! Please rate all posts.

BGP Best Practice / Private-AS vs. Public-AS in the MPLS Core
Dears,
We have recently aquired a large network with ASR9K as Internet Gateways and non-Cisco devices in the MPLS Core.
We would liike to know which is the best recommended solution to use Private MP-BGP AS in the MPLS Core or extend the IGW Public AS, knowing that the IGW will be in a VRF and not the global routing table. Moreover, the clients of the MPLS Core have their own BGP Public AS and would need to connect to the MPLS Core to obtain internet services from the IGW.
(Cust1)------EBGP------[VRF_Cust_1](MPLS CORE AS_2)[VRF_IGW]------EBGP-----(IGW AS_1) in the case of having a private BGP AS in the core
(Cust1)------EBGP------[VRF_Cust_1](MPLS CORE AS_1)[VRF_IGW]------iBGP-----(IGW AS_1) in the case of having same public BGP AS in the core
Waiting for your feedback and thoughts.
Thanks,
Michel.Michel,
if your mpls core is also used for internet transit, then it is best to be a public AS.
if not, then you can leave it be and remove the private AS at your border routers.
If oyu are connecting multiple MPLS networks together to link L2 or L3 VPN services, I think it is easiest to have it all one AS, otherwise you end up with complex designs such as Carrier supporting Carrier (CSC) or Inter-AS option A (vrf lite), B (using vpnv4 at the inter AS gateay) or C (using vpnv4 at the interAS gateway with route reflectors in each AS peering with each other).

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-LunHello 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

Hello All,
I have a query regarding MTU over both DMVPN and MPLS.
I have been running the following command from a windows box
ping x.x.x.x -f -l yyy (yyyy being the buffer size) and x.x.x.x being my remote hosts
I am using the same destination host and have two different paths to it. One over MPLS and one over a DMVPN.
I would have expected to be able to send packets with a higher MTU over the MPLS but for both MPLS and DMVPN the maximum packet size I can send with the DF bit set is the same (1372).
Is this normal behaviour? I though MPLS would have less overhead, so my maximum packet size would be higher in my testsDisclaimer

Generally, MPLS supports an increased MTU, when adding MPLS labels, while VPN tunnels, like DMVPN, don't exceed original MTU, and so, it reduces payload space. So, normally, you should see larger ping buffer DF support across MPLS than DMVPN. However, "normal" can be very much impacted by actual device configurations, including making MTU for DF packets the same for either MPLS or DMVPN. (For example, you might want to make the two paths alike so flows that for any reason need to be redirect from one media path to the other see a consistent MTU.) -
We have a CE router connected to PE router. The CE router is connected via 2 links to the PE router, because we need to create two VRFs on the PE for the traffic coming from the CE to separate the traffic, so we have one vrf per link. We are running OSPF between CE and PE.. Now we need to further separate the traffic up to the CE, so Im thinking of using the VRF lite on the CE.. Can MPLS work with the VRF lite, and how to map the VRF lite VRFs on the CE to the MPLS VPN on the PE?
Is there any config examples?
Thanks in advanceVRF Lite and MPLS-VPN act independently so they can work independently. And there is no specific need for mapping. If link is for VRF A on PE so you can make it part of vrf A in CE as well. Both VRFs are independent of each other.

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.

What is under the switches tab?
Oh -- By the way, that picture is over the size limit defined in the forum rules in tems of pixels, but the file size is okay. I'll let it slide. Watch the bumping as well.
If you want to post the switches tab, upload it to someplace like http://img3.imageshack.us/, copy the thumbnail (which has the link to the original) back here, and you are golden.
I had a bear of a time getting the microphone working on my HP DV4, but it does work. I'll look at the set up when I get home tonight [USA-PDT].
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...

Cisco ASA Site to Site IPSEC VPN and NAT question
Hi Folks,
I have a question regarding both Site to Site IPSEC VPN and NAT. Basically what I want to achieve is to do the following:
ASA2 is at HQ and ASA1 is a remote site. I have no problem setting up a static static Site to Site IPSEC VPN between sites. Hosts residing at 10.1.0.0/16 are able to communicate with hosts at 192.168.1.0/24, but what i want is to setup NAT with IPSEC VPN so that host at 10.1.0.0/16 will communicate with hosts at 192.168.1.0/24 with translated addresses
Just an example:
Host N2 (10.1.0.1/16) will communicate with host N1 192.168.1.5 with destination lets say 10.23.1.5 not 192.168.1.5 (Notice the last octet should be the same in this case .5)
The same translation for the rest of the communication (Host N2 pings host N3 destination ip 10.23.1.6 not 192.168.1.6. again last octet is the same)
It sounds a bit confusing for me but i have seen this type of setup before when I worked for managed service provider where we had connection to our clients (Site to Site Ipsec VPN with NAT, not sure how it was setup)
Basically we were communicating with client hosts over site to site VPN but their real addresses were hidden and we were using translated address as mentioned above 10.23.1.0/24 instead of (real) 192.168.1.0/24, last octet should be the same.
Appreciate if someone can shed some light on it.Hi,
Ok so were going with the older NAT configuration format
To me it seems you could do the following:
Configure the ASA1 with Static Policy NAT
access-list L2LVPN-POLICYNAT permit ip 192.168.1.0 255.255.255.0 10.1.0.0 255.255.0.0
static (inside,outside) 10.23.1.0 access-list L2LVPN-POLICYNAT
Because the above is a Static Policy NAT it means that the translation will only be done when the destination network is 10.1.0.0/16
If you for example have a basic PAT configuration for inside -> outside traffic, the above NAT configuration and the actual PAT configuration wont interfere with eachother
On ASA2 side you can normally configure NAT0 / NAT Exemption for the 10.1.0.0/16 network
access-list INSIDE-NONAT remark L2LVPN NONAT
access-list INSIDE-NONAT permit ip 10.1.0.0 255.255.0.0 10.23.1.0 255.255.255.0
nat (inside) 0 access-list INSIDE-NONAT
You will have to take into consideration that your access-list defining the L2L-VPN encrypted traffic must reflect the new NAT network
ASA1: access-list L2LVPN-ENCRYPTIONDOMAIN permit ip 10.23.1.0 255.255.255.0 10.1.0.0 255.255.0.0
ASA2: access-list L2LVPN-ENCRYPTIONDOMAIN permit ip 10.1.0.0 255.255.0.0 10.23.1.0 255.255.255.0
I could test this setup tomorrow at work but let me know if it works out.

Clientless SSL VPN and ActiveX question
Hey All,
First post for me here, so be gentle. I'll try to be as detailed as possible.
With the vast majority of my customers, I am able to configure an IPSEC L2L VPN, and narrow the traffic down to a very minimal set of ports. However, I have a customer that does not want to allow a L2L VPN tunnel between their remote site, and their NOC center. I thought this might be a good opportunity to get a clientless (they don't want to have to launch and log into a separate client) SSL VPN session setup. Ultimately, this will be 8 individual sites, so setting up SSL VPN's at each site would be cost prohibitive from a licensing perspective. My focus has been on using my 5510 (v8.2(5)) at my corp site as the centralized portal entrance, and creating bookmarks to each of the other respective sites, since I already have existing IPSEC VPN's via ASA5505, (same rev as the 5510 )setup with each of the sites.
First issue I've run into is that I can only access bookmarks that point to the external address for the remote web-server (the site has a static entry mapping an external address to the internal address of the web server). I am unable to browse (via bookmark) to the internal address of the remote web server. Through my browser at the office, I can access the internal address fine, just not through the SSL VPN portal. I am testing this external connectivity using a cell card to be able to simulate outside access. Is accessing the external IP address by design, or do I have something hosed?
Second issue I face is when I access the external address through the bookmark, I am ultimately able to log onto my remote website, and do normal browsing and javascript-type functions. I am not able to use controls that require my company's ActiveX controls (video, primarily). I did enable ActiveX relay, and that did allow the browser to start prompting me to install the controls as expected, but that still didn't allow the video stream through. The stream only runs at about 5 fps, so it's not an intense stream.
I have researched hairpinning for this situation, and "believe" that I have the NAT properly defined - even going as far as doing an ANY ANY, just for testing purposes to no avail. I do see a decent number of "no translates" from a show nat:
match ip inside any outside any

192.168.16.34 is the internal interface for the remote ASA5505
64.x.x.x is the external interface for the remote ASA5505
192.168.17.0, and 192.168.18.0 are two other private LANS behind the remote 5505
As you can see, I have things reasonably wide open - with no port restrictions on this one yet - this is for troubleshooting purposes, and it will get restrictive as soon as I figure this out Right now, the ASA5510 is pretty restrictive, and to be brutally honest, I'm not certain I'm even using the packet tracer 100% proper to be able to simulate coming from the outside of the network through my ASA5510, out to a remote ASA5505, and to a web server behind that 5505. I'm sure that the issue is probably going to be a mix of ACL's between the 5510, and the 5505.
I guess the main question, is Clientless SSL VPN really a good choice for this, or are there other real alternatives - especially since my client doesn't want to have to install, or use an actual client (like AnyConnect), nor do they want to have an always-on IPSEC VPN. Am I going about this the right way? Anyone have any suggestions, or do I have my config royally hosed?
Thanks much for any and all ideas!Hey All, I appreciate all of the views on this post. I would appreciate any input - even if you think it might be far-fetched. I'm grasping at straws, and am super-hesitant to tell my customer this is even remotely possible if I can't have a POC myself. Thanks, in advance!!

Access to VPN and Skype from behind work's firewall
I'm running a Powerbook G4 with OS 10.4.11. At work I have a very fast ethernet connection perfect for internet and Work (Exchange) email, however I can't seem to access my Uni email account, VPN or several other services, notably Skype or iChat (as I work away from my kids during the week this is vitally important). I can ping the server for the VPN and both sets of IT boffins assure me that all appropriate ports are open. I can access the VPN through PCs and I am at the moment broadcasting the internet through my Airport to a PC based laptop which is running Skype quite happily. I can go to a local pub/coffee shop and access all of the services through a WiFi/Airport Network, and I have access to all these services when I'm at home (again through WiFi). What am I doing wrong? Any help would be greatly appreciated
DHi,
yes, the spilt into three subnets did help. I now can see the routers also from the LAN which solves Problem A)
Regarding the access from WAN1 to WAN2 the background is a long story about different flatrates from Provider A and B. To keep it short: DSL is stable but very slow during some hours of the day and attached to WAN2, LTE (4G) is fast but not stable (at least 2-3 hickups per day). Therefore I need the RV042 to keep the LAN clients always online as I need it for my job. The telephone is another issue. The fritzboxes do allow VOIP over their own Internet connection but also using another Fritzbox is possible. I have my telephones connected to the DSL Box (WAN2 = 192.168.179 now) and I have a flatrate for calls to cell phones with my 4G provider (WAN1 = 192.168.178 now). As the 4G keeps failing from time to time it is very annoying when it happens during a telco (and we all know Murphys law). So the ideas is to have the telphones attached to the stable (WAN2) DSL Box and reroute it for calls to cell phones via WAN1 ( which is a feature of the boxes and worked perfectly). If the 4G fails the DSL Box uses its own Internet connection to make the call (but then I have to pay for it).
So I need access from WAN2 (192.168.179) to WAN1 (192.168.178). I tried a static route in the WAN2 Box but it didn't work (I've used the RV042 WAN interface IP: 192.168.179.100 as Gateway).
Kind regards

How do I find and turn Core Audio On.
When I try to open Logic it stops at “Initializing Core Audio”.
I have read the topics page and carried out all the suggestions including starting with the control key down to get into logic. When I do this logic opens and a box comes up with Launch Core Audio Driver, Yes or No. If yes, it freezes, if no I can load it up, but there is no core audio at all when I do.
In the inspector, the CORE AUDIO is greyed out. I have gone to Preferences and ticked the Core Audio box and ticked “Apply” and then it freezes again. Logic cannot see or find the Logic Core Library.
How do I turn Core Audio on? I have No Sound at all. There is no instrument list ( EXS 24, ES1, ES2, Sculpture, Ultrabeat etc) coming up in the I/O box, it only says No Plugin. When I load a previous song there is a line through the I/O instrument and no sound. In the arrange window the audio levels show that there is activity but there is no sound and the instruments are crossed out.
It seems like there is a communication problem between the program and the Core Audio sound banks. Could this have something to do with the drivers? If so, Where can I get the drivers from and how do I put them in.
Does anyone know how to get inside Logic maybe to a lower level so that I can tick some box to get the sounds back again.
If I re-install the program will it fix the problem?
Sorry to be so long-winded but I am in a mess with this, so any kind of advise would be very much appreciated.
Many thanks.
Roy.I haven't had this problem, but on other computers, I have seen some sound functions only work if you don't run certain other things on start-up. Try opening System Resources:Accounts:<your account>:Login Items, and clearing out the list.
Hope you solve it!
