Step 3 show mpls traffic-eng forwarding path-set brief
Use the show mpls traffic-eng forwarding path-set brief command to show the sub-LSPs that originate from the
headend router. The following example shows three sub-LSPs originating at the headend router and going to different
destinations. All the sub-LSPs belong to the same path set, which is a collection of paths. The path set is given a unique
ID, which is shown in the PSID column of the example:
Example:
Router# s

Step 4
show mpls traffic-eng forwarding path-set detail
Use the show mpls traffic-eng forwarding path-set detail command to show more information about the sub-LSPs
that originate from the headend router. For example:
Example:
Router# s
