You must enter the commands in the following task list on every IS-IS router in the traffic-engineered
portion of your network.
Note
MPLS traffic engineering currently does not support routing and signaling of LSPs over unnumbered IP
links. Therefore, do not configure the feature over those links.

DETAILED STEPS
PurposeCommand or Action
configure
Step 1
Enables IS-IS routing for the specified routing instance,
and places the router in router configuration mode.
router isis instance-id
Example:
RP/0/RSP0/CPU0:router(config)# router isis isp
Step 2
•
You can change the level of routing to be
performed by a particular routing instance by using
the is-type router configuration command.
Specifies the IPv4 or IPv6 address family, and enters
router address family configuration mode.
address-family { ipv4 | ipv6 } [ unicast ]
Example:
RP/0/RSP0/CPU0:router(config-isis)#address-family
ipv4 unicast
Step 3
Configures a router running IS-IS to flood MPLS TE
link information into the indicated IS-IS level.
mpls traffic-eng level { 1 | 2 }
Example:
RP/0/RSP0/CPU0:router(config-isis-af)# mpls
traffic-eng level 1
