What is configured in the ISP router when customer is using IP Leased Circuit?
Is the concept of PE present when a customer is using IPLC?
I am only aware that PE are present when MPLS is being used.

The CCNP/CCIE videos only talk about MPLS and not IPLC.

    Prob a late response but ill answer.

    For IPLC the ISP would usually have to build a SDH path for you, then they would implement MPLS TE/L3VPN as well as IP transit (BGP stuff ie communities etc) its more based on what type of services you need to be able to reach @ your geographical locations.

    But basically thats the meat of it.

    As for equipment on the Transmission side the ISP would be using either Alcatel/Ciena/Calix/Huawei for there fiber equipment.

    Big tier 1 carriers are like NTT, GTT, Liberty Global, Level 3 etc should be able to provide IPLC.


    Hope this answers ur SP question

    I am getting confused. IPLC means Layer 2 point to point circuit from customer Point of view.
    Why will the ISP implement MPLS TE/L3VPN as well as BGP?

    From the customer perspective it would be only point to point, however in the ISP core network you would see MPLS l3/TE (with MP-BGP) and BGP with their upstream provider etc`s.

    From your perspective it`s a point to point circuit with your offices etc.
