Enabling MPLS TE
Enable MPLS TE on each node and interface that the MPLS TE tunnel traverses.
Before you enable MPLS TE, perform the following tasks:
•
Configure static routing or IGP to ensure that all LSRs can reach each other.
•
Enable MPLS. For information about enabling MPLS, see "
729H
Configuring basic MPLS
."
To enable MPLS TE:

Configuring a tunnel interface
To configure an MPLS TE tunnel, you must create an MPLS TE tunnel interface and enter tunnel
interface view. All MPLS TE tunnel attributes are configured in tunnel interface view. For more
information about tunnel interfaces, see
Layer 3—IP Services Configuration Guide
.
Perform this task on the ingress node of the MPLS TE tunnel.
To configure a tunnel interface:
Step Command
Remarks
1.
Enter system view.

N/A
2.
Create an MPLS TE tunnel
interface and enter tunnel
interface view.
interface tunnel

mode mpls-te
By default, no tunnel interfaces
exist.
3.
Configure an IP address for
the tunnel interface.
ip address

}
By default, a tunnel interface does
not have an IP address.
4.
Specify the tunnel
destination address.
destination ip-address
By default, no tunnel destination
address is specified.
