Configuring OSPF for ABRs

For each ABR that is running OSPF, use the following commands beginning in global configuration
mode:

Configuring OSPF for Non-ABR Routers

For each non-ABR that is running OSPF, use the following commands beginning in global configuration
mode:

Command

Purpose

Step 1

Router(config)# router ospf process-id

Enables OSPF. You are placed in router
configuration mode.

The process-id is an internally used identification
parameter for an OSPF routing process. It is locally
assigned and can be any positive integer. Assign a
unique value for each OSPF routing process.

Step 2

Router(config-router)# network address mask area

area-id

Specifies the interfaces on which OSPF is to run and
specifies the area to which the interface is
connected. The address is the IP address.

Step 3

Router(config-router)# mpls traffic-eng router-id

Loopback0

Specifies that the traffic engineering router identifier
for the node is the IP address associated with
interface loopback0. (The router identifier is
displayed in the show mpls traffic-eng topology
path command output.)

Step 4

Router(config-router)# mpls traffic-eng area 0

Router(config-router)# mpls traffic-eng area m

Turns on MPLS traffic engineering for OSPF in area
0 and in area m. On an ABR, you must configure
traffic engineering on each area you want tunnels in
or across.
