MPLS BASIC CAPABILITY
CONFIGURATION
MPLS Basic Capability
Overview
Basic MPLS forwarding functions includes LDP session establishment and LSP path
maintenance.
The typical configuration procedure for enabling basic MPLS functions on a
routing switch is as follows:
1 Configure LSR ID
2 Enable MPLS
3 Enable LDP
4 Enter VLAN interface view and enable MPLS and LDP on the interface
Then the routing switch can provide MPLS forwarding and LDP signaling
functions.
If you want to modify the default parameters or enable some special functions, for
example, manually creating LSP or explicit route, you can configure according to
the methods in configuration list. For some complicated functions, configuration
combination may be required.
MPLS Configuration The following sections describe the required configuration tasks for MPLS basic
capability:
■ “Defining MPLS LSR ID”
■ “Enabling MPLS and Entering MPLS View”
The following sections describe the optional configuration tasks for MPLS basic
capability:
■ “Configuring the Topology-Driven LSP Setup Policy”
■ “Configuring an LSP Setup Policy”
■ “Configuring Static LSP”
Defining MPLS LSR ID Before configuring any other MPLS command, it is necessary to first configure the
LSR ID. This ID is usually in IP address format and must be unique in the domain.
Perform the following configuration in the system view.
