Use the following command in EXEC Privilege mode to clear information on route dampening and return
suppressed routes to active state.

By default, the path selection in FTOS is deterministic, that is, paths are compared irrespective of the order
of their arrival. You can change the path selection method to non-deterministic, that is, paths are compared
in the order in which they arrived (starting with the most recent). Furthermore, in non-deterministic mode,
the software may not compare MED attributes though the paths are from the same AS.
Use the following command in CONFIGURATION ROUTER BGP mode to change the path selection
from the default mode (deterministic) to non-deterministic.
Command Syntax
bgp non-deterministic-med
Note: When you change the best path selection method, path selection for existing paths remains
unchanged until you reset it by entering the clear ip bgp command in EXEC Privilege mode.
