SPB and L2VPN with multiple vlan's.
« on: May 12, 2014, 03:33:09 PM »
Hi everyone,

In our datacentres (currently 2) we use stacks of ERS5530 and ERS5510 switches, top of rack. They are all connected to a central stack on both locations and these central stacks are connected with a dual 10G fiber ring. We are now moving to a 3 DC setup and management has promised me some early christmas presents in the form of a few 7024 switches with SPB etc.

I have done some reading and the concept is rather clear to me and very appealing. But I have a few questions.

1. I think I read somewhere that the 5530/5510 setup can, in some way play a role in the SPB cloud, not completely but in some way it can have knowledge of the SPB cloud. Does someone have some information about this, maybe some documenation? And what is the software version on the 5500 set that I need to run to make this possible?

2. One of my customers has a rack in one of my datacentres and they have a connection to an Internet Exchange Point where they have about 50 vlans with a lot of customers etc. The connection to the IXP is in a different DC then the location of the rack and at the moment I have to bring every vlan they use through my network to their rack. Can I create some layer 2 VPN in SPB between ports on all three location and tell the SPB cloud that every vlan entering on one side should be available on the other ports? This would be great because then I can tell them that they just have to configure the VLAN on their uplink port to us and the IXP configures it on the IXP connection and I don't have to do anything anymore.

3. On this IXP port we also use 2 VLAN's that are not used by my customer but only by us (peering and one customer vlan). Can I tell the SPB cloud to bring those 2 vlans somewhere else?

Thanks a lot for this great forum.

1) 2 or 3 years ago, avaya tell about ers 5800 series, that will be stack with 5500/5600 series and support SPBM, but on today I don't now any think about 5800 series

Hi Jan,

the ERS55xx and 56xx does not have the hardware that support SPB.
So native SPB will never come to the ERS55xx or 56xx.
Maybe one day you will see a software for lagacy switches that can intaract with a SPB enabled switch.
For example it would be possible that a lagacy switch signals over LLDP a massage to a direct connected SPB switch so that this switch can setup an I-SID for an new vlan or somethink like that.
I am spekulating here, at the moment there is nothing like this implmented by Avaya or any other vendor as far as I know.

For your second point SPB gives you some options to solve your needs.
You have the T-UNI transparent UNI mode you can think of it like an cable, you could transport everything from one device/port to an other device/port of yor SPB network.
It is completly transparent like an cable.
The other option would be an L2VSN, here you have only to configure the access ports of your SPB network to transport a VLAN/I-SID L2 connection through your SPB network.
It is a lot faster to deploy than the classic VLAN configuration in fact you donīt have to configure any of the uplinks in your SPB network.

3. Yes you can transport transparent these 2 extra VLANs to any device/port in your SPB network that you like.

Good Luck

Hi Jan,

for question 1 maybe you can have a view here:
http://www.michaelfmcnamara.com/files/2014ATF/ATF_2014_Best%20Practice%20Design%20for%20Campus%20Networks%20-%20Steve%20Emert.pptx

Especially Fabric Attach will help the ERS-4k/5k to interact with SPBm in (near) future.

Currently 5500/5600's do not have any ability to interact with SPB.  At some point there sounds like there will be a software release that will allow them to signal for VLAN setup to an SPB enabled device, but that's not today.  I am told there will be a SPB enabled 5000 series switch at some point as well.  But no details on an ETA or capabilities yet.

Hi everyone,

Last week Santa was in my office and brought me 4 shine new 7024 units.
I have succeeded in configuring SPB on them and they seemed very happy together. So far so good.
I have not yet put any data through them so my next steps will be to configure some vlan's etc.

I have found how to configure a T-UNI port and I have found how to configure a single I-SID / VLAN combi.

What I haven't found is how to combine this. Does anyone have some examples of a configuration with T-UNI on a port and on the same port some I-SID to take out a specific vlan to bring this specific VLAN somewhere else?

Hi Jan, that is what I found in VSP-7k's documentation:

"NN47202-510_03_03_ConfiguringVENAFabricConnect.pdf" page 16 ff.

Transparent UNI
A Transparent UNI (T-UNI) maps an entire port or MLT to an I-SID. Transparent UNI configures
a transparent port where all traffic switches on an internal virtual port using the assigned I-SID.
No VLAN is involved in this process. Devices switch tagged and untagged traffic in the
assigned I-SID regardless of the VLAN ID.

The T-UNI port or MLT is not a member of any VLAN or STG and is always in the forwarding state.

You can map multiple ports to a T-UNI I-SID. Multiple ports on the same switch and on other
BEBs can use the common I-SID to switch traffic.


There is a lot of information in that document - pls kindly have a view on that.

Good luck

Hi,

I have read that document too. But this document gives me the impression that you can either create a T-UNI port and switch all vlan's in that port to a different port in the same T-UNI. This is great for service providers when you want to switch all traffic for 1 customer between 2 datacentres but you don't want to be bothered with all the vlan's they are using.

The other thing is a C-VLAN Switched UNI where you can transport one vlan from port A to port B and you can map multiple of those vlan's to a single port.

But if I understand the documentation correctly they are mutually exclusive. I mean, you can't add a port to a T-UNI and then also take one of the VLAN's that comes in on that port and map that vlan to a C-VLAN Switched UNI.

Is this correct? Or is this possible and when this is possible I would be really interested to know how to do that.

Thanks.

If you put a port in a T-UNI I-SID the port will be removed from all other VLANs.
So you can not have a L2VSN wich is bound to a VLAN and a T-UNI i-sid at the same access port.

VSP4000-BEB-1:1(config)#i-sid 1 elan-transparent
VSP4000-BEB-1:1(elan-tp:1)#port 1/23
Adding Ports to Transparent UNI i-sid removes it from all VLANS.
Do you wish to continue (y/n) ? y

Cheers

Thanks,
I understood this now as well and my testing shows me the same.

What we are now going to do is the following:
We create one transparent UNI that holds the majority of our internal vlans that have to be switched between the different datacentres.
Besides that we are going to create a second MLT that connects the SPB core to the stack on every datacentre and this MLT will hold all other vlan's that we get from the outside world. This could be VLAN's towards customers etc. On this MLT every VLAN we have to transport between the different locations will be a seperate I-SID.


Thanks

i have two core networks tied together right now while I'm migrating off the old.  The new is the SPB network .

I have created a layer 2 trunk between them and added all VLANS needed.    On the SPB side, I have taken all those VLANS and created layer two VSN's to propagate them into the SPB cloud.   I am running SPB on all VSP's and also on 20+ ERS stacks and its working great.   

So if you have multiple VLAN mapped to I-SIDs and the SPB network knows about them, you really don't need to use a T-UNI in this case.   

So if you have VLAN 100 at one DC map to 100100, then 100100 can map to vlan 10 at another DC or they could be the same at both DCs.   you're just extending your layer 2 vlan across your entire network at that point without having to change IP address schemes or what have you.
