Implementing IS-IS
You must enter the commands in the following task list on every IS-IS router in the traffic-engineered
Note
portion of your network.
MPLS traffic engineering currently does not support routing and signaling of LSPs over unnumbered IP
Note
links. Therefore, do not configure the feature over those links.
SUMMARY STEPS
1. configure
2. router isis instance-id
3. address-family { ipv4 | ipv6 } [ unicast ]
4. mpls traffic-eng level { 1 | 2 }
5. mpls traffic-eng router-id { ip-address | interface-name interface-instance }
6. metric-style wide [ level { 1 | 2 }]
7. commit
8. show isis [ instance instance-id ] mpls traffic-eng tunnel
9. show isis [ instance instance-id ] mpls traffic-eng adjacency-log
10. show isis [ instance instance-id ] mpls traffic-eng advertisements
DETAILED STEPS
Command or Action
Step 1
configure
Step 2 router isis instance-id
Example:
RP/0/RSP0/CPU0:router(config)# router isis isp
Step 3 address-family { ipv4 | ipv6 } [ unicast ]
Example:
RP/0/RSP0/CPU0:router(config-isis)#address-family
ipv4 unicast
Step 4 mpls traffic-eng level { 1 | 2 }
Example:
RP/0/RSP0/CPU0:router(config-isis-af)# mpls
traffic-eng level 1

Configuring MPLS Traffic Engineering for IS-IS
Purpose
Enables IS-IS routing for the specified routing instance,
and places the router in router configuration mode.
• 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.
Configures a router running IS-IS to flood MPLS TE
link information into the indicated IS-IS level.
