    Frame-Relay – Things to Remember

    By admin | August 15, 2009

    1. When “encapsulation frame-relay” command is issued on an interface, the router will learn all the DLCIs associated with that interface via LMI updates. Then once an IP address is configured on the same interface, InARP request will be sent out on all the learned DLCIs. If the other end is also configured with an IP address, it will reply with its own IP address.
    2. Any DLCIs learned with LMI that are not associated with a subinterface are assumed to be used by the physical interface.
    3. PVC status can be active, inactive, deleted.
    4. Encapsulation types are Cisco (default), IETF; e.g. “encapsulation frame-relay ietf” / “frame-relay interface-dlci 101 ietf” / “frame-relay map ip 10.0.0.1 101 ietf”.
