The example that follows shows how MPLS Manager uses the relationships between the MPLS objects and the underlying physical-transport objects to perform MPLS impact analysis. In addition, the example show how the Global Manager picks up where MPLS Manager leaves off to perform global impact analysis.

Underlying transport failure for the Layer 3 VPN impact example shows the underlying physical-transport failure for the example.
