Preparing the Network for MPLS
MPLS operates on top of normal switch functions, using existing ports, virtual ports, VLANs, etc. The
following network components should already be configured:
following network components should already be configured:
• Configure VLANs that are to be used in the MPLS network. VLANs should be created for both the
backbone interfaces and all other connected devices that will participate in the OSPF network. A
VLAN should exist for each instance in which the backbone connects two routers. VLAN configura-
tion is described in “Configuring VLANs” in the OmniSwitch AOS Release 6 Network Configuration
Guide.

• Assign IP interfaces to the VLANs. IP interfaces must be assigned to the VLANs. Assigning IP inter-
faces is described in “Configuring IP” in the OmniSwitch AOS Release 6 Network Configuration

Guide.
• Assign ports to the VLANs. The physical ports participating in the MPLS network must be assigned
to the created VLANs. Assigning ports to a VLAN is described in “Assigning Ports to VLANs” in the
OmniSwitch AOS Release 6 Network Configuration Guide.

• Configure the Loopback0 interface. Configuring the “Loopback0” IP interface is required on each
switch that will participate as a Label Switching Router (LSR) in the MPLS core network. See the
“Configuring IP” chapter in the OmniSwitch AOS Release 6 Network Configuration Guide for informa-
tion about how to configure the “Loopback0” interface.

tion about how to configure the “Loopback0” interface.
• Set the router primary address or router ID number. (Optional) Depending on the underlying rout-
ing protocol that is used to support the MPLS core, assigning a primary address or identification
number for the participating routers may be required. If this is not done, the router ID defaults to the
primary address. If the primary address is not set, the first operational IP interface address is used by
default. See the “Configuring IP” chapter in the OmniSwitch AOS Release 6 Network Configuration
Guide for more information.

Installing the MPLS Software License
The MPLS protocol is a licensed application and is restricted only to a licensed user. Purchasing a license
part number along with an authorization code from Alcatel-Lucent is required. The authorization code is
then used to generate a license file.
part number along with an authorization code from Alcatel-Lucent is required. The authorization code is
then used to generate a license file.
To generate a license file, install the file on the switch, and active MPLS, do the following:
provide the serial number and MAC address of the switch and the authorization code.
A license file, lmLicense.dat, is generated.
2 Save the lmLicense.dat file in the /flash directory of the primary CMM.
3 To install the license onto the switch, use the
command and reboot the switch.
4 To verify the installation, use the
command.
Note. For multiple entries of serial numbers, MAC addresses, and authorization codes, use a CSV format-
ted file and upload the file on to the website. A single license file lmLicense.dat is generated for all the
switches.
