Why do you override it? MibTable will handle it: if you make
a SET request on a non existing instance, it will create the row.
BTW, within the iprouteEntry you should use "this" instead of
"iprouteEntr::instance". Also you do not need to use
chTempIndex. Instead you may use
Oidx ind(this->index(req->get_oid()));

Best regards,
