This article discusses how to troubleshoot routing protocol issues.
Default Routing Preferences
The following tables lists the default values for route preferences, also referred to as administrative distances. The route with the lowest preference is the most likely to become the active route.
| Route Source | Default Preference |
|---|---|
| Connected | 0 |
| Static | 1 |
| EBGP | 20 |
| OSPF internal | 30 |
| OSPF external | 110 |
| RIP | 120 |
| IBGP | 200 |
