Step 6: Take Appropriate Action

Purpose

Depending on the error you encountered in your investigation, you must take the appropriate action to correct the problem. In this example, an interface is missing from the configuration of router R3.

Action

To correct the error in this example, follow these steps:

1. Include the missing interface in the configuration of transit router R3:

user@R3> edit

user@R3# edit protocols rsvp

[edit protocols rsvp]

user@R3# show

user@R3# set interface so-0/0/3.0 

2. Verify and commit the configuration:

[edit protocols rsvp]

user@R3# show

user@R3# commit

Sample Output

user@R3> edit 

Entering configuration mode

[edit]

user@R3# edit protocols rsvp 

[edit protocols rsvp]

user@R3# show 

interface so-0/0/0.0;

interface so-0/0/1.0;

interface so-0/0/2.0;                        <<< Missing interface so-0/0/3.0

interface fxp0.0 {

    disable;

}

[edit protocols rsvp]

user@R3# set interface so-0/0/3.0 

[edit protocols rsvp]

user@R3# show 

interface so-0/0/0.0;

interface so-0/0/1.0;

interface so-0/0/2.0;

interface fxp0.0 {

    disable;

}

interface so-0/0/3.0;                        <<< Interface now included in the configuration

[edit protocols rsvp]

user@R3# commit 

commit complete

What It Means

The sample output shows that the missing interface so-0/0/3.0 on transit router R3 is now correctly included at the [edit protocols rsvp] hierarchy level. This results in the possibility that the LSP might come up.
