Package mpls (NSP Network Functions Manager

Package mpls

The XML API OSS interface uses the mpls package for the:

configuration of Multiprotocol Label Switching (MPLS) paths and Label Switched Paths (LSPs) on managed routers
provisioning of MPLS paths and LSPs on managed and unmanaged routers

To configure MPLS-signaled LSPs, an MPLS path must first be created between two routers. An LSP can then be created between the two routers and be associated with the MPLS path.

The NFM-P supports the configuration of related protocols such as RSVP and LDP on managed routers. MPLS uses RSVP to set up traffic engineered LSPs. LDP performs label distribution in MPLS networks.

MPLS, RSVP, and LDP are enabled on routing instances on routers. When they are enabled, an MPLS, RSVP, or LDP instance is created on the routing instance on the Network tab on the NFM-P navigation tree. Various functions can then be performed on the instance. For example, Layer 3 interfaces can be assigned to an MPLS instance.

Services are transported across a network using service tunnels, which can use GRE or MPLS as the underlying transport mechanism. For networks that use MPLS, an MPLS mesh and an LSP mesh are created before LSPs are associated with the service tunnels. LSPs and service tunnels are unidirectional, thus both LSPs and service tunnels must be created in both directions.
