Quick Steps for Configuring MPLS
The following prerequisites for configuring the MPLS transport network are required on each router that
will participate as a Label Switch Router (LSR) in the network:
• The IP configuration required to provide a stable IP network topology on which MPLS tunnels will
traverse. This includes the VLAN-port associations and IP interface configuration required to provide
the necessary connections between participating LSRs.
• A Loopback0 interface that will serve as the system IP address to identify the router as an MPLS LSR.
This requirement is specific to the OmniSwitch.
• At least one IP interface that will serve as an MPLS interface (for static paths) or as a Label Distribu-
tion Protocol (LDP) interface.
• Purchase and installation of the Alcatel-Lucent software license required to run MPLS.
The quick steps described in this section are based on the assumption that the above requirements for
configuring an MPLS transport network are in place.
By default, the MPLS and LDP instances are enabled on the switch when the required Alcatel-Lucent soft-
ware license is downloaded and applied.
1 To change the status of the MPLS instance on the switch, use the configure router mpls shutdown
command. For example:
-> configure router mpls no shutdown
-> configure router mpls shutdown
2 To change the status of the LDP instance on the switch, use the configure router ldp shutdown
command: for example:
-> configure router ldp no shutdown
-> configure router ldp shutdown
3 Configure MPLS Label Switched Paths (LSPs) using LDP or static LSPs. To configure LDP, see
“Quick Steps for Configuring LDP” on page 10-5. To configure static LSPs, see “Quick Steps for Config-
uring Static LSPs” on page 10-8.
Note. Optional. Verify the MPLS status for the switch using the show router mpls status command.
For example:
-> show router mpls status
MPLS Status
Admin Status: Up, Oper Status: Up,
Oper Down Reason: N/A
LSP Counts Originate Transit Terminate
Static LSPs 0 4 0
Dynamic LSPs 0 0 0
Detour LSPs 0 0 0
Verify the LDP status for the switch using the show router ldp status command. For example:
