Load Sharing VPLS end

[Julian_Eble]

Hello Community,

I'm having headache about the load-balance on Aggreation Ports.

Our scenery is a MPLS network who the end point are connected by Juniper Routers.
These connections are 10G (20g agg) and have one VLAN VPLS tagged end-by-end.
The traffic doesn't get balanced even when I change the hash-algorithm and the balance type.

Is there any problem using VPLS and LACP?
Extreme introduced the load-sharing VPLS but I think that useful just for the trunk LACP/MPLS, isn't?

Thanks,
Julian Eble

Hello,

The sharing algorithm is most likely at fault here. The L3_L4 streams will use the same link based on hash algorithm. Unfortunately Extreme does not do load balancing 1:1. We will load share but the traffic streams and what links they actually traverse in the share group will be dependent on the hashing algorithm. Traffic analysis would be your best bet here to determine the best share group algorithm to use to help balance the traffic but 1:1 balance will never be guaranteed.

Hey Welisson,

Please see my response below to Julian and Douglas. Any questions further just let me know.

Hi Joe,

So, i know if depends of the traffic will be crossing the link sharing, where it can be unicast, multicast etc, but in my case i'm using all the traffic over vpls, and then, i don't have this traffic distribution or balacing between the link sharing, or be, not even 1:1, 1:2 and so, i have all the traffic been transmitted over only one port of the link sharing, and i not sure if the Extreme can to do that, also why is there Etherchannel/LACP(load Sharing in this case of the Extreme)if i can't using all switch's features?

Tks

Hi Leonardo

So, the question is. Why is there LAG and MPLS and they don't be possible use both at the same time?

in this case of the Julian, he has two interfaces 10Gbp/s in my case i have two interfaces gigabit, so, the ideia is increase bandwith making the LAG, but when we use MPLS we can't enjoy it.

Doesn't be so clear yet. What is reason about this don't work fine?

Hello Leonardo,

I know what you is talking about, but in the end of my tunnel, there's no LSP signalling, just the raw packets...

I'm doing a lab right know, and I getting some conclusions about.
After the end of the VPLS , the LAG are hashing only when there's multiple MAC source, and the switch is not handling about the IP Source and Destionations...

I don't know if was clear enough but I will open a TAC about it...
