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
interface GigabitEthernet1/35
description L2 Connectivity to KBL039SW1 (TEMP)
switchport
switchport access vlan 100
switchport mode dot1q-tunnel
l2protocol-tunnel cdp
CE-1 end config
interface FastEthernet1/0/48
switchport trunk encapsulation dot1q
switchport mode trunk
end
int vlan 100
ip address 10.10.10.1 255.255.255.0
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

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,

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 ?

Cell-relay over MPLS using MGX 8850

we have existing ATM network using TDM links between MGX 8850 & have PVCs for voice & data traffic. We are planning to migrate the same over MPLS network
following is the setup.
MGX1----> PE1 ------>MPLS Cloud ------> PE2 ---->MGX2
As per this plan we will terminate existing TDM trunks to PE routers at both the end & map VPI/VCI values at PE routers for virtual ATM pvcs over MPLS cloud.We are using cell-relay over MPLS with VC mode. My query is, can we enable MPLS L3 & L2 on the same last mile in this scenario? We want to have one IP over ATM interface on same ATM interface at PE router & make that part of VRF & enable L3 MPLS VPN between all the sites for any to any data transfer. For data we don't want to use L2 MPLS as its any to any & it will end up with too many ATM PVCs.
In this setup PE router & MGX will be configured in NNI-NNI at both end. If we want to create one sub-interface at same ATM interface at PE router end, then that port need to be in UNI. Is it possible to use same ATM trunk port as NNI & UNI?
In MGX 8850 we have RPM,AXSM & VISM modules.

the following document should give you some idea,

Secondary Site SRST over MPLS

My company has IPT in our HQ. We have a secondary mfg location in the next town that is connected via a point-2-point T1, and we run VoIP over it. We have a PRI for PSTN access at the HQ. The 2nd location had POTS access until someone canceled them feeling they were unnecessary (pros and cons for that) At both locations we have SRST on a 1760-V.
Our location in CA (HQ is in WI) currently has its own PBX which is dying. I wish to roll out VoIP to it over MPLS, which I would then replace the P2P T1 and put it in the MPLS cloud too. I plan NOT to add a voice gateway at the CA location and just put a switch out there and route all calls through WI (Leaving a POTS line for fax and 911).
Management only worry is if the phones go out at the HQ, CA will be stranded. I said SRST would kick in and maintain call processing, until the batteries ran out. Only THEN everything would be down. (The other scenario would be the HQ building is compromised somehow).
Is it possible if a DR plan is in place that if an extended power loss occurs, or the HQ building is destroyed, that call routing could be established through our secondary location; since everything is connected via MPLS? I know POTS lines would need to be reestablished, but could the second WI location run SRST for the CA site?

I am not asking how to do it, just if it is possible down the road some time. This could sell the plan to management if it is possible.

GRE function over MPLS

Hello,
Has anyone here implemented "GRE function over MPLS"?
Would it be possible to point to some links discussing advantages/disadvantages and some design aspects of the same?
Thanks
Cheers,
~sultan

Hello Harold,
Thanks for replying, actually just thought about it, considering the existing customer (P2M) who's running GRE on IPLC links, they want to continue the same after migrating to MPLS, just curios to know whether this implementation has been implemented by anyone and whether it could be improved further.
Thanks
Cheers,

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

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

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.
For more information, see the following URL:

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 ).

Implementing SAN over MPLS

Hello,
we have 2 datacenter (backup), we need to implement SAN over MPLS (perhaps with copper : G.SHDSL, or FO ), is it possible ?
and how can we interconnect the 2 MDS, (through our WAN connexion, router, firewall, IPS...?) or connect directely the MDS to IP MPLS (without other equipment, in this case is it secured ?), with witch interterfaces we interconnect 2 MDS via MPLS?

MPLS networks can pose a challenge for FCIP
If you do implement FCIP over MPLS, be sure to monitor for out of order TCP packets on the FCIP interfaces. Within an MPLS network, individual FCIP packets may take different paths though the network based on the current network load. This could lead to TCP packets arriving at the destination FCIP interface out or order in some instances. OOO (out of order) packets can lead to decreased performance. I have seen a few MDS install decide to use static routing within the MPLS network to avoid a high % of OOO.
The CLI command to monitor for OOO is
show ips stats tcp interface gigabit x/y detail
Under TCP receive stats, look for Out of Order packets. Be sure to monitor both ends. You might see OOO is 1 direction, and not the other.
Hope this helps,
Mike

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:
http://www.cisco.com/univercd/cc/td/doc/product/software/ios120/120newft/120limit/120s/120s22/12s10k.htm
For 7200, 7500, and 12000 series, you can do port mode EoMPLS:

L2TPv3 over MPLS

Hi folks,
I've to implement two L2TPv3 tunnels over MPLS backbone, primary and backup. I'm thinking about L2 pseudowires, but my question is: with 2 pseudowires, how could I do, if possible, to create a primary and a backup tunnel? Something like FRR?
I've found in a recent post a configuration for two tunnels:
http://forum.cisco.com/eforum/servlet/NetProf?page=netprof&forum=Network%20Infrastructure&topic=WAN%2C%20Routing%20and%20Switching&CommCmd=MB%3Fcmd%3Dpass_through%26location%3Doutline%40%5E1%40%40.1ddda49d
but no idea about how to implement a fault tolerance solution.
Any advice will be appreciated
Thanks
Andrea

Andrea,
I think I understand where my confusion comes from. You are using L2TPv3 in a context of VPDN rather than using it as a transport a pseudowire, right?
In this case the L2TPv3 session could just be routed as IP traffic through the core. Or if you want to use pseudowires through the core, it would certainly be possible to use MPLS for this purpose.
Let me know if that helps,

Xconnect 20Gb Port-channel over MPLS Possible?

Can anybody confirm if you can establish an Xconnect between two 20Gb port-channels (2x 10Gig bundle). The core is 40Gig and running MPLS. We have many gigabit pseudowires running over it already.
Our intention is to terminate 10Gig server traffic on 4900M's and then have a 20Gb Port channel trunk link into a 6500 (which is part of the MPLS cloud). We would then issue the xconnect directly on the 20Gig port channel in order to traverse the MPLS Core.
Has anyone configured this before? Are there any caveats to watch out for? What sort of performance hit (if any does) xconnect functionality have on 10Gig Traffic.

Hi,
Yes it's supported but test it first (as always ;-) )
