In this example, we have reduced the adjust-time interval for next-hop evaluation of static routes from 60 to 30 seconds. This has the obvious effect of improving convergence times for networks with static routes, but it also has some negative consequences. If you have a lot of static routes, setting the adjust-time interval too low can cause CPU overhead problems.
