Has anyone tell what is "candidate default"? By the way, we often see one route path has been marked "*" on its prefix when multiple equal cost route paths presenting at "show ip route x.x.x.x". What does it mean?
When you have equal cost paths to a destination the router will do per-packet or per-destination load sharing.
The * is next to the route that is being used at that precise moment for forwarding packets. If you kept running the same command "sh ip route x.x.x.x" you should see the * moving between the three route entries.
