This table contains an entry for each frame relay DCE
virtual interface. This interface is called virtual
because it does not necessarily reflect to a single
hardware interface; it is possible to either narrow
(many hardware interfaces looking as a single virtual)
or widen (a single hardware interface with several VCs
is mapped to several virtual interfaces) the interface.
Entries in this table are created manually and will result
to the creation of a multiprotocol routing interface in
the ifTable. This interface can than be used by higher
level protocols like ip, ipx and bridging.
The object frMprIfIndex shall be set to 0 for creation
of new entries. The BRICK will allocate the next free
interface index and assign it to frMprIfIndex.
Rows of this table can be deleted by setting the object
frMprEncapsulation to the value delete.
This object contains an interface index and assigns the
row to an entry in ifTable. When creating new entries
in the table, the value of this object shall be set to 0.
The next free ifIndex value is than allocated
by the BRICK and assigned to the object. At the same
time a new interface is created in the IfTable.
This object specifies the encapsulation method to be used.
If this object is set to mpr, the encapsulation method
described in Q933a is used for the protocols IP, IPX
and transparent bridging. This encapsulation is also
explained in RFC 1490.
