  • Page 18: Lsp Establishment Procedure

    ZXR10 8900 Series User Manual (MPLS Volume) Topology-based drive is to distribute labels for corresponding routes of routing protocols. When a LSR deals with route up- date of OSPF or BGP, the LSR modifies the entries in label for- warding table, meanwhile the LSR distributes labels for these entries.

    In MPLS, there are two label distribution modes: � Downstream-on-Demand (DoD) � Downstream Unsolicited (DU) In MPLS, there are two label control modes: � Independent � Ordered In MPLS, there are two label holding modes: � Liberal � Conservative Confidential and Proprietary Information of ZTE CORPORATION...

  • Page 22: Label Distribution Mode

    ZXR10 8900 Series User Manual (MPLS Volume) By default, devices of ZTE use DU mode, independent mode and liberal mode. Label Distribution Mode In a MPLS system, a downstream LSR distributes labels for specific FEC and informs upstream LSR. That is, labels are designated by down stream and distributed from down stream to up stream.

  • Page 23: Label Control Mode

    LSR1 uses conservative label holding mode. In liberal label holding mode, a LSR can adapt itself to route changes quickly. In conservative label holding mode, a LSR can reduce the number of label bindings. Confidential and Proprietary Information of ZTE CORPORATION...
