This section provides a brief overview of the tasks to configure MPLS and provides the CLI commands.
The following protocols must be enabled on each participating router:
MPLS
RSVP-TE (for RSVP-TE-signaled MPLS only)
LDP
In order for MPLS to run, you must configure at least one MPLS interface in the config>router>mpls context.
An interface must be created in the config>router>interface context before it can be applied to MPLS.
In the config>router>mpls context, configure the path parameters. A path specifies some or all hops from ingress to egress. A path can be used by multiple LSPs.
When an LSP is created, the egress router must be specified in the to command and at least one primary or secondary path must be specified. All other settings under the LSP hierarchy are optional.
