Interface names associate an IP address to the interface, and then associate the IP interface with a physical port. The logical interface can associate attributes like an IP address, port, Link Aggregation Group (LAG) or the system.
There are no default interfaces.
Note that you can configure a VPRN interface as a loop-back interface by issuing the loop-back command instead of the sap sap-id command. The loop-back flag cannot be set on an interface where a SAP is already defined and a SAP cannot be defined on a loop-back interface.
The following is a sample VPRN interface configuration output.
