Once you have created a path, you can modify the path.

1. For this example, a three node path named sf_to_sj was configured as follows.

   vyatta@vm1# set protocols mpls-rsvp globals explicit-paths sf_to_sj explicit-route-objects 10 address 2.2.2.2
   vyatta@vm1# set protocols mpls-rsvp globals explicit-paths sf_to_sj explicit-route-objects 20 address 4.4.4.4
   vyatta@vm1# set protocols mpls-rsvp globals explicit-paths sf_to_sj explicit-route-objects 30 address 6.6.6.6
   

2. To modify the path named sf_to_sj to include a node between the first and second node, insert a new entry using a number between 10 and 20 for the explicit-route-objects parameter.

   vyatta@vm1# set protocols mpls-rsvp globals explicit-paths sf_to_sj explicit-route-objects 15 address 3.3.3.3

3. Modify the sf_to_sj path again to delete the node with explicit-route-objects set to 20 (this node became the third node in step 2; it was originally the second node in step 1).

   vyatta@vm1# delete protocols mpls-rsvp globals explicit-paths sf_to_sj explicit-route-objects 20

4. Display the resulting sf_to_sj path.

   vyatta@vm1# show protocols mpls-rsvp globals explicit-paths 
    explicit-paths sf_to_sj {
           explicit-route-objects 10 {
                   address 2.2.2.2
           }
           explicit-route-objects 15 {
                   address 3.3.3.3
           }
           explicit-route-objects 30 {
                   address 6.6.6.6
           }
    }
