  1. Hey there.  Great video.  Thanks for taking the time.  Just a small clarification, for viewers, if I may.  At around 1:16:00, it was mentioned that L2VPN requires VRF, RD and RT on PE routers.  To clarify:  If you are simply creating point-to-point EoMPLS VCs, there is no requirement for BGP; IGP and LDP is all that is needed in the control plane.  If you are using VPLS (layer 2 multi-point-to-multi-point), an RD is only required if you intend to use BGP for VC signalling and end-point auto discovery.  Otherwise, if your intention is just to do static VPLS, no RD is necessary because no BGP is necessary.

  2. At around the 1:05:30 point Rob you talk about setting up the CE-PE IGP using OSPF. You explain the process of creating a new OSPF process tied to the customer VRF. It was not quite accurate because OSPF does not support address-family configuration. Instead the command should be router ospf X vrf Y Where X is the OSPF process number (2). And Y is the VRF name (vrf Cust_A) in other words to initialize the OSPF process the command should be router ospf 2 vrf Cust_A
