Configuring the Graceful Deletion Timeout Interval

The router that initiates the graceful deletion procedure for an RSVP session waits for the graceful deletion timeout interval to ensure that all routers along the path (especially the ingress and egress routers) have prepared for the LSP to be taken down.

The ingress router initiates the graceful deletion procedure by sending the Admin_Status object in the Path message with the D bit set. The ingress router expects to receive an Resv message with the D bit set from the egress router. If the ingress router does not receive this message within the time specified by the graceful deletion timeout interval, it initiates a forced tear-down of the LSP by sending a PathTear message.

To configure the graceful deletion timeout interval, include the graceful-deletion-timeout statement at the [edit protocols rsvp] hierarchy level. You can configure a time from between 1 through 300 seconds. The default value is 30 seconds.




graceful-deletion-timeout seconds;

You can configure this statement at the following hierarchy levels:

[edit protocols rsvp]
[edit logical-systems logical-system-name protocols rsvp]

You can use the show rsvp version command to determine the current value configured for the graceful deletion timeout.
