If you plan on migrating routing protocols or have multiple routing protocols it’s important to note the administrative distance values so you are aware of which route preferences will be based on the protocol.

You can change the preferences of protocols by changing the values to a lower value.

Remember: The lower the number, the higher the routing preference (IE: OSPF with a value of 110 will be preferred over RIP with a value of 120).

 

The table below compares Cisco and Juniper Distance values below to show vendor similarities:
