Node Models

The MPLS model suite supports workstation, server, router, and link models from the standard model library. The LER (Label Edge Router) and LSR (Label Switching Router) node models in the MPLS object palette are preconfigured to support MPLS. However, you can configure any of the router models in the standard model library to model LERs and LSRs.

Model Attributes

Global MPLS attributes, which are used to configure network-wide MPLS parameters, are grouped in the MPLS configuration object. Router-specific MPLS attributes are grouped in the MPLS Parameters attribute on each router. They are described in Router Attributes on page SPM-6-6.

MPLS Configuration Object Attributes

Some of the important MPLS configuration object attributes are described below.

•FEC Specifications This attribute specifies the Forwarding Equivalence Class (FEC) parameters used by MPLS in the network. FECs classify and group packets so that all packets in a group are forwarded the same way. FECs are based on any of the IP header fields—ToS, Protocol, Source Address Range, Destination Address Range, Source Port, and Destination Port can all be used to define a FEC. Figure 6-2Specifying FEC Attributes on page SPM-6-4shows the attribute sequence for defining an FEC.
