# Basic MPLS Configuration Tasks

Configuring an MPLS network includes the following sets of tasks:

- MPLS Global Configuration Tasks—Perform these tasks to configure settings common to all MPLS usage on a given LSR
- (Optional) LDP and RSVP-TE Interface Profile Configuration Tasks—Perform these tasks to configure LDP or RSVP-TE interface profiles
- MPLS Interface Configuration Tasks—Perform these tasks to configure each interface on an LSR that uses MPLS
- MPLS Tunnel Configuration Tasks—Perform these tasks to configure MPLS tunnels or topology-driven LSPs
- (Optional) MPLS Tunnel Profile Configuration Tasks—Perform these tasks to configure a profile that contains settings to be used by multiple MPLS tunnels
- Tunnel or topology-driven LSP tasks—Perform these tasks to configure MPLS tunnels or topology-driven LSPs

Many users find it convenient to configure MPLS by completing the tasks in each set of tasks before moving to the next set. However, you do not have to complete the tasks in the listed order. For example, you might perofrm all the pure MPLS tasks relevant to your network and then perform all the relevant LDP or RSVP-TE tasks.

The type of network you want to implement determines which sets of tasks you must complete, as indicated in Table 25.

Table 25: Configuration Tasks by Type of Network

Task Set | Traffic Engineering Network | Topology-Driven Network (Best-Effort, Hop-by-Hop, LDP)
--- | --- | ---
Global | Yes | Yes
Interface Profile | Optional | Optional
Interface | Yes | Yes
Tunnel | Yes | No
Tunnel Profile | Yes | No

In addition to the basic configuration tasks, you might need to perform other LDP or RSVP-TE configuration tasks.

- Additional LDP Configuration Tasks—Perform these tasks to configure LDP features depending on your network design
- Additional RSVP-TE Configuration Tasks—Perform these tasks to configure RSVP-TE features depending on your network design
