Chapter 2 MPLS Basic Capability Configuration
2.1 Introduction to MPLS Basic Capability
The following MPLS basic capabilities are available:
Basic MPLS forwarding
Each router interface supports the basic MPLS forwarding function, including label
packet forwarding and TTL processing.
LDP session establishment and LSP maintenance
Each interface supports LDP session and supports the loop detection in both maximum
hop count mode and path vector mode. It can create and delete LSPs.
It also supports loose routing and strict explicit routing: You can also specify LSPs.
Besides MPLS basic functions, V 2.41 also provide performance monitoring and fault
diagnostic tools.
To enable basic MPLS functions at a router, you should complete the following
configuration tasks:
1)
Configure LSR ID
2)
Enable MPLS
3)
Enable LDP protocol
4)
Enter interface view and enable interface LDP function
Then the router can provides MPLS forwarding and LDP signaling functions.
If you want to modify the default parameters or enable some special functions, for
example, creating LSP, creating explicit route, you just configure according to the
method in configuration list. For some complicated functions, configuration
combination may be required.
Currently, MPLS is not available on the following interfaces:
Serial interface encapsulated with X.25 or MP
ATM interface
Dialer interface
Virtual template interface
2.2 MPLS Basic Capability Configuration
