Ethernet over MPLS/VPLS

Hi,
I would appreciate if you answer my following questions :
- As you know EoMPLS is based on physical port, but how about VPLS?
- Could you tell me minimum router which supports VPLS?
- Any other solutions for transfer ethernet frames over MPLS except VPLS and EoMPLS?
- I think VPLS is better EoMPLS because it supports multipoint to multipoint ,is it true? could you please tell me VPLS advantage and disadvatage?
Regards,
M.Arshad rad

Ehlo ,
1)EoMPLS is available in port and vlan mode.Since VPLS
is actually using martini encapsulations ( both lasserre and kompella ) it is possible to use raw and tagged modes.
2)IMHO only Cisco router that supports VPLS now is 7600.Additionaly VFI can be only assigned to SVI.
3)Juniper CCC ( RSVP based ) - but obviously you won't use it since it's proprietary ( nevertherless it has nice feature like lsp-stiching ) and IOS couldn't signall it .
4) VPLS is designed to support p-to-mp and therefore
it's more complex.IF you don't need its features you can stick with raw p2p martini , which is relatively simple and widely implemented ( no problem for example to configure it between ios and junos boxes ).

Sample Configuration For Ethernet over MPLS.

I am looking for a sample configuration and scenario for the Ethernet over MPLS.I would appreciate if I get some explaination with it.How the LDP is configured for the directed sessions (as per Martini draft) and the auto discovery (as per kompella draft) with respect to Ethernet over MPLS.Cam anyone help me in this ?

Here's a sample EoMPLS configuration on the PE routers:
R1:
interface Loopback0
ip address 1.1.1.1 255.255.255.255
interface Ethernet0/0.10
encapsulation dot1Q 10
! 10 = vcid must match the vcid configured on the other side
mpls l2transport route 2.2.2.2 10
R2:
interface Loopback0
ip address 2.2.2.2 255.255.255.255
interface Ethernet0/0.10
encapsulation dot1Q 10
mpls l2transport route 1.1.1.1 10
The LDP directed session will be setup automatically by the router when the xconnect statement is configured.
Cisco IOS doesn't support the Kompella Draft.

Can someone explain about frame header size in Ethernet over MPLS

Can someone explain about frame header size in Ethernet over MPLS

Hello Arun,
Here is some explanation:
http://cciethebeginning.wordpress.com/tag/eompls/
Also I attached pcap file, you can open it in wireshark and look at entire packets. There are some pings 10.0.0.1 <-> 10.0.0.2 between CEs

FR over MPLS

Dears,
hope you support me understtanding the following:
i have the following topology:
now i need CE1 and CE2 communicate to CE3 ( CE3 connected to mpls through ethernet) over MPLS cloud and be aware that mpls cloud working perfectly but my head stund at how to make CE1 and CE2 connect to customer VRF on PE router through FR switch .
please i need your support.
thanks in advance

Check whether you have enabled IP CEF .
ip cef distributed !
CEF switching is pre-requisite for label Switching frame-relay switching

Can I send bridge traffic over MPLS backbone?

Can someone let me know if bridging can be done across a MPLS backbone? If yes, please provide a brief config sample or let me know where I can find documentation. Thanks

You can provide Ethernet over MPLS. The configuration can depend on platform - here is a configuration guide for the 7600 series:
http://www.cisco.com/en/US/products/sw/iosswrel/ps5013/products_feature_guide09186a0080088187.html
EoMPLS is also on 12000 and 10720:

Point to Mulipoint L2VPN trunks over MPLS

Can we have trunk between more than 2 CE over MPLS in short we are looking for the point to multipoint MPLS L2 VPN where more than 2 CE will share the common ethernet segment over MPLS to share the vlan database
Let me give more info @ solution which we are trying find out
CE1,CE2,CE3 & CE4 are the core switches at respective location, we are looking for the same vlan database between these core switches over the MPLS
CE1 will be connected to PE1
CE2 will be connected to PE2
CE3 will be connected to PE3
CE4 will be connected to PE4
so can we have the L2 vpn between CE1,CE2,CE3 & CE4 where the interface connected to respective PE's will be TRUNK ?

hi
thanks for the pdf, I had tried the VPLS earlier. the circuit are coming up but I am not able to ping between CE's Vlan ip address although VC are up
PE end config

other end vlan 100 ip address is 10.10.10.2 but not able to ping this ip address from CE-1
any guess what cpuld be the problem?

Ask the Expert:Concepts, Configuration and Troubleshooting Layer 2 MPLS VPN – Any Transport over MPLS (AToM)

With Vignesh R. P.
Welcome to the Cisco Support Community Ask the Expert conversation.This is an opportunity to learn and ask questions about concept, configuration and troubleshooting Layer 2 MPLS VPN - Any Transport over MPLS (AToM) with Vignesh R. P.
Cisco Any Transport over MPLS (AToM) is a solution for transporting Layer 2 packets over an MPLS backbone. It enables Service Providers to supply connectivity between customer sites with existing data link layer (Layer 2) networks via a single, integrated, packet-based network infrastructure: a Cisco MPLS network. Instead of using separate networks with network management environments, service providers can deliver Layer 2 connections over an MPLS backbone. AToM provides a common framework to encapsulate and transport supported Layer 2 traffic types over an MPLS network core.
Vignesh R. P. is a customer support engineer in the Cisco High Touch Technical Support center in Bangalore, India, supporting Cisco's major service provider customers in routing and MPLS technologies. His areas of expertise include routing, switching, and MPLS. Previously at Cisco he worked as a network consulting engineer for enterprise customers. He has been in the networking industry for 8 years and holds CCIE certification in the Routing & Switching and Service Provider tracks.

Hi Tenaro,
AToM stands for Any Transport over MPLS and it is Cisco's terminology used for Layer 2 MPLS VPN or Virtual Private Wire Service. It is basically a Layer 2 Point-to-Point Service. AToM basically supports various Layer 2 protocols like Ethernet, HDLC, PPP, ATM and Frame Relay.
The customer routers interconnect with the service provider routers at Layer 2. AToM eliminates the need for the legacy network from the service provider carrying these kinds of traffic and integrates this service into the MPLS network that already transports the MPLS VPN traffic.
AToM is an open standards-based architecture that uses the label switching architecture of MPLS and can be integrated into any network that is running MPLS. The advantage to the customer is that they do not need to change anything. Their routers that are connecting to the service provider routers can still use the same Layer 2 encapsulation type as before and do not need to run an IP routing protocol to the provider edge routers as in the MPLS VPN solution.
The service provider does not need to change anything on the provider (P) routers in the core of the MPLS network. The intelligence to support AToM sits entirely on the PE routers. The core label switching routers (LSRs) only switch labeled packets, whereas the edge LSRs impose and dispose of labels on the Layer 2 frames.
Whereas pseudowire is a connection between the PE routers and emulates a wire that is carrying Layer 2 frames. Pseudowires use tunneling. The Layer 2 frames are encapsulated into a labeled (MPLS) packet. The result is that the specific Layer 2 service—its operation and characteristics—is emulated across a Packet Switched Network.
Another technology that more or less achieves the result of AToM is L2TPV3. In the case of L2TPV3 Layer 2 frames are encapsulated into an IP packet instead of a labelled MPLS packet.
Hope the above explanation helps you. Kindly revert incase of further clarification required.
Thanks & Regards,
Vignesh R P

Multicast paging over DMVPN over MPLS

We're using IPcelerate as our paging solution and have the need to extend the application across our MPLS/VPLS network. I'm looking for a configuration or, at the very least, some guidance to get this working across a DMVPN over said MPLS/VPLS.
Regards,
-Mike M.

Hi Michael
I have been in a similar situation before of having Paging to traverse over the WAN IP MPLS network with SingleWire Paging system. If we are talking about Audio paging, it is built on the IP multicast networking and thus to extend this service to remote offices connected through IP MPLS network, the Service provider should enable IP multicast over its VRFs for you. In my case it was not feasible by the Service provider(s). SingleWire introduced a solution of a Paging Gateway that is integrated with the paging server and it is located at the remote office. The Paging server sends the target audio mulitcast as a unicast session to the paging gateway in the remote office and then the paging gateway sends on the LAN as a multicast .
I am not sure if IPcelerate has a similar solution, but it is worth asking and validating.
Hope that helps

Ethernet over Mains solution??

Hi All, at the moment my desktop PC is hardwired into the router but due to building work that needs to change, at least temporarily. So I’m thinking about Ethernet over Mains adaptors. While I’m doing it I would really like an adaptor by the TV. So I need three devices, one for the router, one for the TV and one for the desktop.
I know that these things don’t share surge adaptors and a few other things and I’m not quite sure about putting one on a standard extension lead, so I’m looking for adaptors with pass through mains.
If it makes a difference I already have a Devolo dLan 500 AVtriple+ on the way from Amazon that I ordered thinking it was a triple pack, not a single triple adaptor but £60+ I was expecting to get the solution for that not a single device. Also I don’t need them to be wireless and I only get 5mbps broadband and if I need a high volume transfer between devices, which is rare, I would be ok plugging into the router which is a home hub 2.
Having already messed up I am starting my research again but thought I would ask here in case somebody has already solved this or has any advice.
Thanks for any help.

Hi Thompson,
I have just set up a powerline network, using devolo devices.
So, basically you want to plug your router into a network device, so your internet connection can be shared remotely by your PC and your TV/Sky using ethernet cables? Devolo do three pack setups, in the following guises - the second option having powerline pass through connectors...
You could go for either this:
Devolo dLAN 500 Duo Network Kit
or this (power pass through):
Devolo dLAN 500 Duo Plus Network Kit
I am only stating devolo as I have knowledge of them, and are a piece of cake to set up - literally plug in and away you go, you don't even have to bother with the software that comes with them to monitor the network if you don't want to, although it is worth it as it will auto detect the firmware on the devices and let you know if there are updates available.
Devolos support seems pretty good as well, I am currently in the middle of a very extensive email exchange with their support team in Germany because i emailed them purely enquiring why I couldn't see a device on an old laptop using their software.They have been very helpful so far.
Dare I say it I would stick with the 500mbps as devolo no longer produces the 200 versions, although are still available from various outlets.
You could buy another make, getting a two pack and a third single adaptor, but I don't think there will be much difference in price when all told. At least with the above packs they are all in one box.
For additional information, I don't find these drop off in terms of speed that much. I have a device plugged in upstairs which is connected to my router, then I have a 500Av Triple + Wireless downstairs, into which is linked a slingbox and my sky box, and a wii connected wirelessly. The transfer speed between the two devices shows 494mbs, so a drop off of 6mbs. I also have an older 200 Av in another room, which shows a transfer speed of around 178mbs.
Hope the above helps.

How to provied Redundancy for VRF MGMT with help of BGP over MPLS(MPBGP)

Hi,
Please find the Network Topology.
This is One Remote site and mamaged by Mgmt office.
All devices on remote site is accessed by MGMT Office. My organisation seek for Redundancy for Managing devices.
My administration is from MGW to R1. I am new to MPLS.
AS u can see in diagram, R1 have 3 VRF(Voice,Signal and MGMT).Currently i have primary link over whitch we are running MPBGP.
Traffic from these VRF goes to this primary link. Currently Secondary link is not connected.
Now my organisation proposed for the secondary link and they want that only traffic from VRF -- MGMT should go through MPLS RTR R2 (the secondary link ) , when the mgmt routes not learned from MPLS RTR R1 (Connected to the SP1 ).
Current R1 config
There is IBGP betweem R1 to both MPLS RTR.
BGP Config

so what configuration need to done at R1 to achiev the redunancy for MGMT vrf ?
if possible please reply with sample configuration.
or
IN MPBGP protocol, where i will apply routing policy to apply as- path prepand    so that Route would be secondary to neighbor.
IGP-OSPF and BGP over MPLS is running.
on Which address-familiy nbr,should i apply, is it in VPNV4 or IPV4 or IPV4 VRF ?
if i want 10.36.128.0/26 prefix should go to Neigbhor MPLS R2, what should i use access-list or Prefix list?
please provide the reply with its config .
thanks in advance,

Metro Ethernet over Docsis

Hello Gurus,
I would like to know a bit more about this tecnologie (Metro Ethernet over Docsis).
I work for a cable companie and we would like to know the implicationd of implementing such a technologie.
If we go for a CPE based aproach we only have to configure a CPE like the Cisco 1805 in each costumer end-point?
Which configurations does the CMTS and backbone require?
What are the maximum speed we can offer with this technologie running on HFC?
Any help would be much appreciated.
Thanks in advance.

Ethernet over coax question

I have a coax cable running from the front house to the back house and want to connect my router to the iMac back there that serves up music and movies etc to the rest of the house. It's currently connected via wifi, but there are dropouts etc.
I've been pointed to a few different devices that can run ethernet over coax, such as this one:
http://www.netsys-direct.com/proddet...NH-310C&cat=27
there are a variety of them, and they all seem to say they have speeds in the 100mps to at the most 500 mps. My questions is this. How fast are current Airport and Ethernet speeds? I know they speak of Gigabit wireless, so does that mean 1000mps and up?
If I'm currently using wireless in this case, do you think switching to coax would slow things down a lot, or would it work ok?
thanks!

802.11g aka "wireless-g" has a maximum theoretical speed of 54 megabits/second.
802.11n "wireless-n", has a maximum theoretical speed of 300 megabits/second, but to attain that it requires near-perfect conditions. It's normal to observe less than half that in actual use.
These vary according to many environmental phenomena that influence radio propagation. Observed speeds tend to be considerably less. "Gigabit Ethernet" isn't so influenced, but may also be less than 1000 Mb/s due to other network factors.

GRE over MPLS

Hello people,
im facing problem trying to establish a GRE tunnel over mpls. The topology goes as follows:
(server) ----CE1(6500)-----PE1(6500)----vrf cloud-----CE2(6500)--FW
-server needs to establish a gre tunnel with FW.
-server receives a default route from CE1 via OSPF.
-CE1 has an default static route pointing to the next hop which is an interface VLAN (in a vrf) on PE1.
- PE1 receives a default route generated by CE2 (via mpbgp).
In this situation the GRE tunnel wouldnt come up.The only way i got the GRE to work was replacing the default static route on CE1 with a more specific static route.
On both cases (default AND specific static routes) the connectivity(ping) from end to end was there.
Has anybody seen anything alike?
thanks,
Bruno

You could be looking at some recursive routing throug the GRE interface, so the second it comes up it will try to put the GRE packets through the GRE tunnel, this creating a loop. Are you using a dynamic routing protocol to get network info over the GRE tunnel or a static route if so, how is it setup ?

Routing protocol over mpls

Hi all,
i have to implement a network customer over a vpls provider ( 60 site L2 any to any).
which protocol for this design ? eigrp, ospf or bgp with advantage or inconvenient?
thanks,

If this is to be a layer 2 network for 60 sites with any to any connectivity then you can choose which ever routing protocol you wish since the provider will not be participating in the routing protocol. BGP would be at the bottom of my list for this for several reasons, one of which is that BGP does not do dynamic neighbor discovery and I would not want to manually configure 59 neighbors on each of 60 routers.
Either OSPF or EIGRP could be good choices. If we knew more about this network it might be possible to favor one or the other. For OSPF it seems likely that you would have a single area and some people might be concerned about 60 peers in a single area. But I think it could be appealing that most routers would go through full adjacency with only two peers where with EIGRP each router would negotiate neighbor relationship with 59 neighbors. Another consideration might be what the topology of the sites is like. If each site has several subnets and if the subnets fall into summarizable ranges then EIGRP might be preferred since it enables summarization from each of the routers which reduces the complexity of the routing table on each neighbor.

VoIP, Video Polycom over MPLS

Hi
Any one using Vidoe polycom and VoIP over MPLS? We have around 5 offices and they want to use Video Polycom over MPLS. If someone can provide Pro and Con for that and any document or link much appreciate it. Thanks in advance.
Sai

i havnt done polycom over mpls
but i would like to give u hints to consider it
the first think u need to know from the ISP what COS they put in as priorty and how many COS they provide u based on SLA and how match max traffic then they start to drop traffic
the other think is to know how the polycom mark the traffic and u need to calssifiy it and put it in proper calss based on the classes provided by the mpls ISP
good luck
and hope this helpful
