DETAILED STEPS
Command or Action Purpose
Step 1
configure
Example:
RP/0/RP0/CPU0:router# configure
Enters global configuration mode.
Step 2
router isis instance-id
Example:
RP/0/RP0/CPU0:router(config)# router isis isp
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.
Step 3
address-family {ipv4 | ipv6} [unicast |
multicast]
Example:
RP/0/RP0/CPU0:router(config-isis)#
address-family ipv6 unicast
Specifies the IPv4 or IPv6 address family, and enters router
address family configuration mode.
• This example specifies the unicast IPv6 address family.
Step 4
mpls traffic-eng level {1 | 2}
Example:
RP/0/RP0/CPU0:router(config-isis-af)# mpls
traffic-eng level 1
Configures a router running IS-IS to flood MPLS TE link
information into the indicated IS-IS level.
Step 5
mpls traffic-eng router-id { ip-address |
interface-name interface-instance }
Example:
RP/0/RP0/CPU0:router(config-isis-af)# mpls
traffic-eng router-id loopback0
Specifies that the MPLS TE router identifier for the node is
the given IP address or an IP address associated with the
given interface.
