This variable states whether the Enhanced Link
Management Interface(ELMI) address registration(AR)
mechanism is enabled or not on a frame relay
interface. A value of 1 indicates ELMI AR is
supported on the interface. A value of 2 indicates
ELMI AR is supported but the user disabled the
exchange of IP address and ifIndex with the
neighboring device. This object doesn't have any
significance if cfrElmiLinkStatus is disabled
on the interface.
