The feature is present even as far back as VAX.

Here is a link to some older documentation that shows up from a quick 
search.

Look for pseudo-interfaces.

Note that this applies to the HPE TCP/IP product.

The Process Software Multinet and TCPware products will have different 
commands for setup, assuming they offer equivalent functionality.
