Cisco Cisco IOS Software Release 12.0(14)S

To configure an MPLS traffic engineering tunnel, perform these steps in interface configuration mode. 

To configure a path option that specifies an exclude address in Step 6, specify the explicit 
keyword (not the dynamic keyword) and specify an IP explicit path configured according 
to the steps in “Configuring IP Explicit Address Exclusion.”

Router(config)# interface tunnel 

Configures an interface type and 
enters interface configuration mode.

Router(config)#

 

Gives the tunnel interface an IP 
address. 

An MPLS traffic engineering tunnel 
interface should be unnumbered 
because it represents a unidirectional 
link.

Router(config-if)# tunnel destination A.B.C.D

Specifies the destination for a tunnel. 
The destination of the tunnel must be 
the MPLS traffic engineering router 
ID of the destination device.

Router(config-if)# tunnel mode mpls traffic-eng

Sets the tunnel encapsulation mode to 
MPLS traffic engineering.

Router(config-if)# tunnel mpls traffic-eng bandwidth bandwidth

Configures the bandwidth for the 
MPLS traffic engineering tunnel. 

Router(config-if)# tunnel mpls traffic-eng path-option number 

{dynamic | explicit {name path-name | ID path-number}} [lockdown]

Configures the tunnel to use a named 
IP explicit path or a path dynamically 
calculated from the traffic 
engineering topology database. A 
dynamic path is used if an explicit 
path is currently unavailable.

Router# show ip explicit-path

Shows information about configured IP explicit 
paths.

Router# show mpls traffic eng tunnels

Shows information about tunnels, including the 
current tunnel path if a tunnel is operational. By 
viewing the command output, you can determine 
the path that was used to build a tunnel. If you 
entered the exclude-address command, the 
specified link or node should not be listed.
