Activating Traffic Engineering on the Interface
To activate traffic engineering on the physical interface, enter the following commands beginning in
global configuration mode:
Configuration Example for Activating Traffic Engineering on the Interface
Example 20-2 configures TE on a physical interface using the IS-IS routing protocol.
Example 20-2 Activating Traffic Engineering on a Physical Interface with IS-IS
Router(config-if)# ip address 10.1.1.1 255.255.255.255
Router(config-if)# ip rsvp bandwidth 130000 130000 sub-pool 80000
Router(config-if)# mpls traffic-eng tunnels
Router(config-if)# ip router isis
Command Purpose
Step 1
Router(config)# interface type number
Configures an interface and enters interface configuration mode.
type is the type of interface (for example, serial).
number is the number of the interface (for example, 1/0/0).
Step 2
Router(config-if)# ip rsvp bandwidth
interface-kbps [sub-pool kbps]
Enables Resource Reservation Protocol (RSVP) for IP on an
interface.
interface-kbps specifies the amount of bandwidth (in kbps) on an
interface to be reserved. Valid values are from 1 to 10,000,000.
(Optional) sub-pool kbps is the amount of bandwidth (in kbps) on
an interface to be reserved to a portion of the total. Valid values
are from 1 to the value of interface-kbps.
Note The sum of bandwidth used by all tunnels on this interface
cannot exceed interface-kbps and the sum of bandwidth
used by all sub-pool tunnels cannot exceed sub-pool kbps.
Step 3
Router(config-if)# mpls traffic-eng
tunnels
Enables MPLS traffic engineering tunnel signaling on the
interface.
Step 4
Router(config-if)# ip router isis
Enables the IS-IS routing protocol on the interface.
Note Do not enter this command if you are configuring an
OSPF configuration.
