MPLS Application Example
This section provides an example network configuration in which the Label Distribution Protocol (LDP) is
used to set up both static and signaled Label Switched Paths (LSPs). In addition, a tutorial is also included
that provides steps on how to configure the example network topology using the Command Line Interface
(CLI).
Example Network Overview
The following network diagram represents an MPLS network consisting of four routers. Static LSPs are
configured between routers R1, R2, R3, and R4 using interfaces “vlan-1”, “vlan-20”, “vlan-30” and “vlan-
50”. An additional link between routers R3 and R4 on the “vlan-40” interface has OSPF and LDP signal-
ing enabled.
Example MPLS Network
Static LSPs require the manual configuration of static routes and VC labels on each router interface in the
static path. LDP signaling, however, uses the underlying routing protocol to set up LSPs and dynamically
discover routes and labels.
