<div>Hi Frank,</div>
<div> </div>
<div>Are you talking about an lan extension service / pseudowires / vpls / etc ie. Ethernet that the carriers are tunneling over MPLS?</div>
<div>If that is the case, it should be delivered as a simple ethernet circuit to you. Of course you can do load balancing over 2 ethernet links, you can play with metrics and have redundancy too. You cannot have both though obviously (if you use >100Mb/s). Something to consider if you are load balancing like this: the circuits will have different latency and packets *will* get out of order.</div>
<div> </div>
<div>The best advice however is you should contract a consultant or a company to fully understand what you want to achieve and give you case specific guidance.</div>
<div> </div>
<div>If everyone in your situation got free 'professional services' on these forums, we would all be out of jobs! :)</div>

<div>Best of luck</div>

<br>Here is the context: I am currently having a datacenter presence where I do run my own AS with three ISPs, each with full BGP table and a /23 PI dedicated to the servers and Internet access. Because this is considered as the consolidated Internet access and datacenter, I would like to hub the office with this connection.<br>
<br>Now my goal is to connect the office with the datacenter using a symmetric 100/100 Mbit link running MPLS service from my ISP. This will be delivered as a service. Now, because redundancy is important for me, I would link to have a second link 100/100 Mbit, but rather than asking the same provider to secure the path, I would like to ask this to a second provider because I do not trust one provider to do redundancy for me.<br>
<br>I know that each provider are using physical different path to reach the Data Center.<br><br>Questions:<br><br>1) Can I build a redundant MPLS access with two different providers and aggregate them together on each end? Thus having two paths of 100 Mbit symmetric each. Possible?<br>
2) What equipment do I need on the office side to do this?<br>3) How long is the convergence time to expect in case of major failure on one of the links?<br><br>Thank you for your time and advices.<br><font color="#888888"><br>
