IOS 15.2(3)T
As part of the simplification initiative, IOS 15.2(3)T brings a lot of changes. Table below summarizes the changes for load-balancing and resolvers.
| Current Solution | After 15.2(3)T |
| Support utilization and range resolvers | Remove utilization and range resolvers |
| Delay, range, utilization resolvers are the default resolvers | No default resolver. PfR automatically does load balancing |
| Do random resolver for all qualified exits that satisfy the configured criteria | Do load balancing for all qualified exits that satisfy the configured criteria then random selection |
| Cost resolver can be configured with a higher priority than performance resolver in a policy | No priority option for resolver cost-min. It is always handled after any performance resolver |
| Trigger range OOP by comparing the load of an exit to all other exits. | Trigger range OOP by comparing the load of an exit to all other exits in the same group. |
| Check the soft limit before calling the resolver | Check soft limit of all exits before entering the resolver. If none of exits are below the limit, make selection by ignoring the soft limit. |
