Configuring MPLS in a Network
Configuring MPLS in a network is a
1)Create LSPs in the network topology
2)Create FECs and traffic trunks in the MPLS Configuration object
3)Configure LERs to direct packets into the appropriate LSPs
After this basic configuration is in place, you can add QoS/differentiated services (DiffServ) constraints or traffic shaping parameters.
Creating LSPs
After you create your network topology, you can add LSPs to the network. There are three methods of adding LSPs to your network:
•From traffic conversation pairs
•By drawing the LSPs in the Project Editor workspace
•From text files
The Update LSP Details operation creates traffic profiles and forward equivalence classes (FECs) for the LSPs, which you can modify later as you
The model supports both static and dynamic LSPs using the strict and loose path objects in OPNET. To create LSPs, use the standard procedure for creating paths as described in the Building Models chapter of the User Guide manual (Guru product documentation) or the Communication Mechanisms chapter of the Modeling Concepts manual (Modeler documentation).
You can create dynamic LSPs automatically using the Create LSPs From Traffic Conversation Pairs utility or manually using the standard procedure for creating path objects.
The Create LSPs From Traffic Conversation Pairs utility creates LSPs quickly based on some or all of the traffic conversation pairs in the network.
Procedure 6-1 Creating Dynamic LSPs from Demands
1From the Protocols > MPLS menu, choose Configure LSPs from Demands.
➥ The Assign IP Addresses dialog box appears.
