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
