MPLS Traffic Engineering (TE) IS-IS Configuration

Hello Rene / Network lessons,

We are going to install a new MPLS circuit to connect the client locations. The client is asking to test the MPLS circuit to make sure its working fine and we are receiving the expected bandwidth. The client requirement is that they will not have their routers/equipment to test it. We will have to test it on the MPLS service provider equipment.

How can we accomplish this? I guess we can use iperf command to test the speeds of a circuit right? But then how to test it if we do not have our equipment? Can we connect our laptop/PC directly to the termination point where the ISP ends its MPLS circuit? How do we connect it, using RJ45 cable or console?

Please reply. I need to know this fast. Thanks in advance.
