MPLS Multilink PPP Support and Core Links
The figure below shows a sample topology in which Multiprotocol Label Switching (MPLS) is deployed over
Multilink PPP (MLP) on provider edge-to-provider (PE-to-P) and P-to-P links. Enabling MPLS on MLP for
PE-to-P links is similar to enabling MPLS on MLP for P-to-P links.
Figure 2: MLP on PE-to-P and P-to-P Links
You employ MLP in the PE-to-P or P-to-P links primarily so that you can reduce the number of Interior
Gateway Protocol (IGP) adjacencies and facilitate the load sharing of traffic.
In addition to requiring MLP on the PE-to-P links, the MPLS Multilink PPP Support feature requires the
configuration of an IGP routing protocol and the Label Distribution Protocol (LDP).
