Cisco IOS Release: Multiple releases (see the Feature History table)
DETAILED STEPS
Configuring MPLS TE Forwarding Adjacency
To configure an MPLS TE forwarding adjacency, use the following command in interface configuration
mode:
mode:
Note
You must configure a forwarding adjacency on two LSP tunnels bidirectionally, from A to B and B to A.
Otherwise, the forwarding adjacency is advertised, but not used in the IGP network.

Configuring IS-IS for MPLS TE Forwarding Adjacency
To configure an IS-IS metric for an MPLS TE forwarding adjacency, use the following command in
interface configuration mode:
interface configuration mode:
Command or Action
Purpose
Step 1
enable
Example:
Router> enable
Enables privileged EXEC mode.
•
Enter your password if prompted.
Step 2
configure terminal
Example:
Router# configure terminal
Enters global configuration mode.
Step 3
interface tunnel
number
Example:
Router(config)interface tunnel 0
Designates a tunnel interface for the forwarding adjacency.
Command
Purpose
Router(config-if)# tunnel mpls traffic-eng
forwarding-adjacency
{holdtime value}
Advertises a TE tunnel as a link in an IGP network.
Command
Purpose
Router(config-if)# isis metric default-metric
{level-1 | level-2}
Configures the cost metric for a tunnel interface to be used as a
forwarding adjacency.
forwarding adjacency.
Note
You should configure the isis metric command with level
1 or 2 to be consistent with the IGP level at which you are
performing traffic engineering. Otherwise, the metric has
the default value of 10.
