Step 5: Verify the RSVP Protocol Configuration

Purpose

After you have checked RSVP sessions, interfaces, neighbors, and determined that there might be a configuration error, verify the RSVP protocol configuration.

Action

To verify the RSVP configuration, enter the following command from the ingress, transit, and egress routers:

user@host> show configuration protocols rsvp

Sample Output

user@R1> show configuration protocols rsvp 

interface so-0/0/0.0;

interface so-0/0/1.0;

interface so-0/0/2.0;

interface fxp0.0 {

    disable;

}

user@R3> show configuration protocols rsvp 

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;

}

user@R6> show configuration protocols rsvp 

interface so-0/0/0.0;

interface so-0/0/1.0;

interface so-0/0/2.0;

interface so-0/0/3.0;

interface fxp0.0 {

    disable;

}

What It Means

The sample output shows that R3 has interface so-0/0/3.0 missing from the RSVP protocol configuration. This interface is critical for the correct functioning of the LSP.
