PVCs are created at layer 2.
DLCIs: Data-link connection Identifiers : are used to identify virtual circuit connections.
DLCI address are assigned by the provider and then mapped to IP addresses by the router
LMI: Local management Interface

Setup of Frame Relay on Cisco
#interface
#encapsulation frame-relay [ietf, or default is cisco]
use default to talk to other cisco routers, use ietf encapsulation to talk to non-cisco.
#frame-relay interface-dlci
to map dlci number to current interface, or subinterface
Then specify an IP address for that subinterface
Optionally you can hard-code the address on the other end.
#encap frame-relay [ietf]
#no inverse-arp
turns off auto addressing features
#ip address
#frame-relay map ip
this lets you mix encap types, and allow broadcast over interface
