EF CheckSum Manager 23.10 free12/27/2023 Two downstream mapping TLVs are supported. Information for each downstream hop in the path of an LDP FEC or an RSVP LSP. The sender and responder nodes to exchange and validate interface and label stack The downstream mapping TLV is used in LSP ping and LSP trace to provide a mechanism for Performs various checks to see if it is intended to be a transit LSR for the path. Packet is sent to the control plane of each transit Label Switching Router (LSR) that Whether the packet reaches the egress label edge router (LER), while for LSP trace, the Trace are modeled after the ICMP echo request or reply used by ping and trace to detectįor a specific LDP FEC, RSVP P2P LSP, or BGP IPv4 or IPv6 labeled route, LSP ping verifies Ping provides a mechanism to detect data plane failures in MPLS LSPs. The router LSP diagnostics include implementations of LSP ping and LSP trace based on RFC 8029,ĭetecting Multi-Protocol Label Switched (MPLS) Data Plane Failures. LSP diagnostics for LDP, RSVP, and BGP labeled routes: LSP ping and LSP trace ThereĪre diagnostics for MPLS LSPs, SR policies, SDPs, services, and VPLS MACs within a The suite of OAM diagnostics supplement the basic IP ping and traceroute operations withĭiagnostics specialized for the different levels in the service delivery model. Verify that a service is operational, a set of in-band, packet-based Operation,Īdministration, and Maintenance (OAM) tools is supported, with the ability to test eachįor in-band testing, the OAM packets closely resemble customer packets to effectively test the customer's forwarding path, but they are distinguishable from customer packets so they are kept within the service provider's network and not forwarded to the customer. Packets to a service, VC labels to a service, and each service to a service tunnel mustīe performed properly in the forwarding plane for the service to function properly. For example, operations such as the association of Delivery of services requires that a number of operations occur properly and at different levels
