Cisco Cisco IOS Software Release 12.0(22)S

This section includes the following:

For detailed descriptions of the commands and their arguments, see the Cisco IOS IP Command 
Reference, Volume 2 of 3: Routing Protocols manual.

To view an example, go to 

.

To configure an MPLS traffic engineering tunnel, use the following commands beginning in global 
configuration mode:

To configure explicit paths, use the following commands beginning in global configuration mode:

Router(config)# interface 

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 

Specifies the destination for a tunnel. You must enter the MPLS 
traffic engineering router ID of the destination device.

Router(config-if)# tunnel mode mpls 

Sets the tunnel encapsulation mode to MPLS traffic engineering.

Router(config-if)# tunnel mpls 

 bandwidth

Configures the bandwidth required for the MPLS traffic 
engineering tunnel. 

Router(config-if)# tunnel mpls 

 number 

 {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. The path-option must specify the ABRs the tunnel LSP 
must traverse as “loose” hops via the next-address loose command.

Router(config)# ip explicit-path 

 number enable

Enters the subcommand mode for Internet Protocol (IP) explicit 
paths and creates or modifies the specified path.

Router(cfg-ip-expl-path)# next-address 

Specifies the next loose IP address in the explicit path. Each ABR 
the path must traverse should be specified in a next-address loose 
command.
