Can someone confirm that VPLS is supported on the Cisco ASR1001?
With the feature navigator it looks like the ASR1001 is the only ASR1000 series router with VPLS support but I can't find any documentation confirming this.

Hi,
I was reading up about the new features Cisco are adding in 3.5S and VPLS IS DEFINITELY LISTED.
Platform: Cisco ASR 1000 and Cisco ASR 903
For detailed information, see the following Cisco documents:
http://www.cisco.com/en/US/docs/ios-xml/ios/mp_l2_vpns/configuration/xe-3s/mp-vpls.html
http://www.cisco.com/en/US/docs/routers/7600/install_config/12.2SR_OSM_config/mpls.html

This is absolutely Cisco great! Adding VPLS to the ASR1000 platform and will increase the ASR's
usefulness considerably for smaller ISP POP/Edge sites by providing a pure Layer 2 VPN (E-Lan/E-Line) service.
Cisco should expect sales of ASR1000's to increase!
While IOS-XE v3.5S is not yet available to be downloaded, I'm looking forward to trying it out when Cisco release it.
The VPLS support appears to support static neighbors (no intergration to MP-BGP / Auto-Discovery) but it's a good start

According to this doc, it is supported in ASR 1000 series routers
.
The aggregation network uses a fairly complex array of both Layer 2 and Layer 3 technologies such as Virtual Private LAN Services (VPLS), IEEE 802.1Q (QinQ), IP, Layer 2 VPN (L2VPN) Pseudowire, MPLS VPN, and MPLS Traffic Engineering (MPLS-TE) in order to backhaul subscriber traffic in a very reliable and very scalable fashion back to aggregation devices (broadband network gateway [BNG] ─ as defined in DSL Forum TR-101) and network services operating in the network.
Here is the doc

Thank you for your response!
According to this document VPLS is not supported on the ASR1000 series.
http://www.cisco.com/en/US/docs/ios/ios_xe/3/release/notes/asr1k_feats_important_notes_33s.html
In your document it could also be just general information about protocols used in "The aggregation network" instead of protocols supported by the ASR1000 routers.
According to the feature navigator it is supported on the ASR1001 but I can't find any document indicating the ASR1001 is an exeption on the other ASR1000 routers so it is all a bit confusing.

Hi,
Can someone from cisco ot with access to a xe3.5 confirm the configuration example in the docs is correct.
http://www.cisco.com/en/US/docs/ios-xml/ios/mp_l2_vpns/configuration/xe-3s/mp-vpls.html
It is based on switchport and interface vlan from the 7600 and not the EVC and bridge doamins from ASR1K
Thanks

Hi Nitzan
I don't have access to an ASR router to test it but I think it should be possible to configure VPLS on the layer 3 interface of an bridge-domain the same way as you should do it when using switchports.
So the configuration of PE1 of your link should be something like this:
l2 vfi PE1-VPLS-A manual vpn id 100 neighbor 2.2.2.2 encapsulation mpls neighbor 3.3.3.3 encapsulation mpls ! interface Loopback 0 ip address 1.1.1.1 255.255.255.255
This configures the CE device interface:
interface FastEthernet0/0 service instance 1 ethernet
bridge-domain 100
Here the attachment circuit (VLAN) is associated with the VSI.
interface vlan 100 no ip address xconnect vfi PE1-VPLS-A
02-11-2012 10:44 PM
Hi,
Thanks for your answer but the L3 interface of bridge doamin is BDI not VLAN
http://www.cisco.com/en/US/docs/ios-xml/ios/cether/configuration/xe-3s/ce-ether-vc-infra-xe.html
http://www.cisco.com/en/US/docs/routers/asr1000/configuration/guide/chassis/bdi.html
In any case the documentation should be accurate for the platform
Thanks

Not all is well with the 1001 and 1002 ASR when doing the VPLS. You can create a VFI but you cannot attach it to anything. xconnect VFI exists nowhere on any interface to include BDI interfaces.
Does anyone know where this magical "xconnect vfi" attachment point will be created?

Hi,
Great timing, I actually tested the lastest images just last week and ran into the same problem... however I started checking around.
I didn't have a 2nd ASR1000 available at the time but the following config takes just I don't know if it works. I am planning to test it later this week or early next week.
I think Cisco are ramping up some great services on the ASR1000 platform and bringing it into line with the higher end routers available like the ASR9K which I think are great.
In the process of reearching the feature I stumbled across a cisco doc stating that the traditional method of switching / bridging (using the command 'bridge-group [num]') had been grandfathered. I can't recal if it was in that same doc that I found the physical 'service instance' command that appears to associate the Vlan on a particular interface with a bridge-domain. The 'service instance' allows pushing and popping of Vlan tags too (from memory the ASR1000 syntax was the same or very similar to what I've set-up on the ASR9K platform).
So then I was able to associate the bridge-domain with the VFI... so what do you think? If it's bridging to the VFI then the 'interface' assocaited to the L2 VPN VPLS defined.
I could be completely wrong with this and the IOS code has not been completed yet or the Cisco documentation is yet to be updated. If you have a couple spare ASR1000's I don't suppose you can test it out otherwise I will be within the next couple weeks?

No matter what I try I cannot get anything as an attachment circuit.

Hi,
Do you have solve the problem ?I have the same problem .
Thanks!

Hello Antonio,
Thank you for the information. It is definitely good news that Cisco will add VPLS support to the ASR1000 series.

Jasper
