Command
Purpose
Step 1
Router(config)# router isis
Enables IS-IS routing and specifies
an IS-IS process for IP. This
command places you in router
configuration mode.
an IS-IS process for IP. This
command places you in router
configuration mode.
Step 2
Router(config-router)# mpls traffic-eng level-1
Turns on MPLS traffic engineering
for IS-IS level 1.
for IS-IS level 1.
Step 3
Router(config-router)# mpls traffic-eng level-2
Turns on MPLS traffic engineering
for IS-IS level 2.
for IS-IS level 2.
Step 4
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.
router identifier for the node is the IP
address associated with interface
loopback0.
Step 5
Router(config-router)# metric-style wide
Configures a router to generate and
accept only new-style TLVs (type,
length, and value objects).
accept only new-style TLVs (type,
length, and value objects).

Purpose
Step 1
Router(config)# router ospf process-id
Configures an OSPF routing process
for IP. You are placed in router
configuration mode.
for IP. 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.
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)# mpls traffic-eng area n
Turns on MPLS traffic engineering
for OSPF area n.

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.
router identifier for the node is the IP
address associated with interface
loopback0.
