Implementing MPLS Traffic Engineering
P2MP Topology Scenario: Example
This section describes a typical scenario of point-to-multipoint traffic engineering toplogy. This figure illustrates
the P2MP toplogy.

This head router describes the configuration at head node. This router does the imposition of MPLS at head
node.
