This object represents the Network Layer Address of the
source that originated the last invalid packet. The type
of address stored depends on the value in
cpimLastErrorOriginType.
The value of this object represents the Network Layer
Address of the Designated Router (DR) whenever the value
of cpimLastErrorGroup is a zero-length address,
for eg. when encapsulated IP header is malformed.
The value of this object is irrelevant if the value of
cpimLastErrorType is none(1).
