Best practice would be to always use subinterfaces for your
Frame Relay configurations. If there are no protocols (i.e. IPv4, IPv6)
on the main interface it doesn't matter what PVCs exist there. However
since the CCIE Lab Exam isn't a test of best practices you should be
aware of dealing with problems of Inverse-ARP and such.
