Modifying a path

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

Complete the following steps to modify a 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
            }
     }
