Dear Mohammad

 

Please refer to the below link

on-statement/optimize-timer-edit-protocols-mpls.html

 

Also please consider the following:

The optimize timer is a timer that starts @ a certain time and runs
frequently on the period you define, for example if you set the optimize
timer to 3600 seconds, it will run for example @ 2:15 pm the next time it
will check the best paths will be @ 3:15 pm, and it does not run when there
is a change in lsp paths, when it runs it see if there are lsp changes or if
there are suboptimal path and returns to network to best paths selection,
and it relies on your IGP protocol ospf/isis.

Another option would be smart optimize timer, which respond immediately to
network changes as below link:

collections/config-guide-mpls-applications/mpls-configuring-the-smart-optimi
ze-timer.html

 

you need also to take to be cautious when defining the optimize timer
interval since it consumes the resources, I would suggest setting it to a
value above 1 hour.
