You can delete and re-establish a CR-LSP by running the reset mpls rsvp-te command. This command is used to verify the working process of RSVP-TE in special cases. Generally, this command is not needed.
If this command is run in an attempt to restart RSVP-TE and the interval at which RSVP-TE is restarted is small, the attempt fails. The interval varies according to the number of LSPs. The more the LSPs are established, the longer the interval is. The interval can be set to 30, 60, 90, or 120, in seconds.
