Implementing MPLS Traffic Engineering

Configure an Interarea Tunnel: Example

The following configuration example shows how to configure a traffic engineering interarea tunnel. Router
R1 is the headend for tunnel1, and router R2 (20.0.0.20) is the tailend. Tunnel1 is configured with a path
option that is loosely routed through Ra and Rb.
Specifying the tunnel tailend in the loosely routed path is optional.
Note
configure
explicit-path name path-tunnel1
The following configuration example shows how to configure loose-path retry period (range is 30 to 600
seconds) on headend router.
config
mpls traffic-eng
timers loose-path retry-period 120
The following configuration example shows the global configuration for loose hop expansion affinity or metric
on ABR.
config
mpls traffic-eng path-selection loose-expansion affinity 0xff
mpls traffic-eng path-selection loose-expansion metric te class-type 5

Configure Forwarding Adjacency: Example

The following configuration example shows how to configure an MPLS-TE forwarding adjacency on tunnel-te
68 with a holdtime value of 60:
configure
interface tunnel-te 68
forwarding-adjacency holdtime 60
