I'm not sure where you are looking, but those params are indeed present in the

Charles,
What is the machine configuration you're running on? It seems that there
are two MCA parameter for the tcp btl: btl_tcp_if_

Charles, I recall using the I_MPI_NETMASK to choose which interface for MPI to
use.
I guess you are asking the same question for OpenMPI?

Is there a way to limit the IP addresses or network interfaces used for
communication by OpenMPI? I am looking for something similar to the
I_MPI_TCP_NETMASK or I_MPI_NETMASK environment variables for Intel MPI.
The OpenMPI documentation mentions the btl_tcp_if_include and
btl_tcp_if_exclude MC
