Network Management, MIBs and MPLS: Principles, Design and Implementation

The creation of LSPs, such as the one illustrated in Figure 8-2, involves the following steps:

  • Enabling MPLS on MPLS-capable interfaces ( mplsInterfaceConfTable ). Our examples assume that this administrative step has been executed.

  • Configuring in-segments (via the mplsInSegmentTable ) on LSRs and egress LERs (not needed on ingress LERs).

  • Configuring out-segments (via the mplsOutSegmentTable ) on LSRs and ingress LERs (not needed on egress LERs).

  • Setting up the cross-connect table to associate segments and/or to indicate connection origination and termination ( mplsXCTable ).

  • Configuring a tunnel object to point to the cross-connect on the ingress LER.

  • Optionally specifying label stack actions ( mplsLabelStackTable ).

  • Optionally specifying segment traffic parameters ( mplsTrafficParamTable ).

We now look at these steps in more detail.
