The next time if you find that pim neighbourship is not coming up for a customer which is coming through l2tpv3 to MPLS enabled PE, might hit with the bug which is not listed in cisco bug tool kit. During the lab, we find the issue and look for the cisco site for bug but do not find any information. IOS used for l2tpv3 is entservices9 12.3(14)T5.The weird behavior which was seen is that PIM neighborship is coming up at CE end but not at PE end. If migrate the customer over GRE then it works fine because we were bypassing l2tpv3.
SDN and NFV is the next phase of technology change which will help service provider to launch the services in single click. This is all about the programmability of the networks by using open source software defined network controller.
