MPLS-TE Configuration Example
MPLS-TE Configuration Example
Figure 18-3 illustrates the sample network that the configuration commands reference. Example 18-5
lists relevant portions of the configuration files for enabling MPLS-TE on ML-Series card A in the
sample network. ML-Series card A is configured with an explicit path.

Command Purpose
Step 1 Router(config)# interface tunnel Configures an interface type and enters interface configuration
mode.
Step 2 Router(config)# ip unnumbered loopback0 Gives the tunnel interface an IP address.
An MPLS-TE tunnel interface should be unnumbered because it
represents a unidirectional link.
Step 3 Router(config-if)# tunnel destination
A.B.C.D
Specifies the destination for a tunnel.
Step 4 Router(config-if)# tunnel mode mpls
traffic-eng
Sets the tunnel encapsulation mode to MPLS-TE.
Step 5 Router(config-if)# tunnel mpls
traffic-eng autoroute announce
Specifies IGP should use the tunnel (if the tunnel is up) in its
enhanced shortest path first (SPF) calculation.
Step 6 Router(config-if)# tunnel mpls
traffic-eng bandwidth bandwidth
Configures the bandwidth for the MPLS-TE tunnel.
Step 7 Router(config-if)# tunnel mpls
traffic-eng
path-option number {dynamic |
explicit }{name path-name |
path-number} [lockdown]
Configures the tunnel to use a named IP explicit path or a dynamic
path.
