Configuration for Edge Label Switch Routers, LSR-A and LSR-B
Before configuring the routers for the MPLS controlling function, it is necessary to perform the initial
router configuration. As part of this configuration, you must enable and configure the ATM Adapter
interface.
Then you can set up the extended ATM interface for MPLS. The IGX ports can be configured by the
router as extended ATM ports of the physical router ATM interface, according to the following
procedures for LSR-A and LSR-C.
To configure the routers performing as label edge routers, use the procedures in the following tables.
Configuration of a Cisco Router as an Edge Router, Edge LSR-A
Proceed with configuration as follows:
Step 15
Router LSC2 (config-if)# Router OSPF 5
Sets up OSPF routing and assigns a process ID of 5
which is locally significant. The ID may be chosen
from a wide range of available process ID up to
approximately 32,000.
Step 16
Router LSC2 (config-router)# network 142.4.0.0
0.0.255.255 area 10
Step 17
Router LSC2 (config-router)# network 142.7.0.0
0.0.255.255 area 10
