no cspf
Use this command to disable the use of the Constrained Shortest Path First (CSPF) server for all RSVP sessions. Disable CSPF when no nodes support the required traffic engineering extensions.
When this command is executed in Router mode, CSPF is disabled for all configured RSVP sessions, and all RSVP sessions configured from this point forward. If the default CSPF per RSVP session is enabled, it will be disabled. The CSPF status for RSVP sessions can be verified using the
show rsvp session command with the detail option.
Use the
cspf command to revert to the default settings.
Note: When CSPF is disabled, path is not calculated taking constraints into consideration. Path message is sent to the next hop based on IGP best route. In this case, ERO is not included in path message and all constraints are included.
