MPLS consists of 3 components:

1. MPLS forwarding

2. MPLS signalling

3. Mapping layer 3 traffic onto MPLS LSPs



The document mpls-forwarding basics explains item 1.



Examples of MPLS signalling protocols are: RSVP-TE LDP and CR-LDP.

The package ldp-portable is an implementation of LDP and contains more

information about LDP based MPLS signalling.



Mapping of layer 3 traffic to MPLS LSPs is accomplised in a couple of

different ways.

-Per FEC where FEC is an entry in the routing table

-Virtual interface that represents an LSP
