Step 4: Verify RSVP Interfaces

Purpose

Display the status of each interface on which RSVP is enabled to determine where the configuration error occurred.

Action

To verify the status of RSVP interfaces, enter the following command from the ingress, transit, and egress routers:

user@host> show rsvp interface

What It Means

Sample Output 1 shows that even though each router has interfaces that are up and have RSVP active, there are no reservations (Active resv) on any of the routers. In this example, we would expect at least one reservation on the ingress and egress routers, and two reservations on the transit router.

In addition, interface so-0/0/3 on transit router R3 is not included in the configuration. The inclusion of this interface is critical to the success of the LSP.

In contrast to Sample Output 1 and to illustrate correct output, Sample Output 2 shows the relevant interfaces with active reservations.
