    Are we talking about DECnet here?   If so, then that's not true.
VMS is
perfectly happy with two NI interfaces.   Both have the same DECnet
address
and therefore the same MAC and are presumably connected to different
physical networks.   It'd be a mess if you connected them both to the same
LAN segment, of course.   IF the VMS node is a router, it'll happily route
DECnet traffic between the two interfaces and their associated networks.

    I'm doing it now - LEGATO is configured this way.

And I'd like to point out that what you describe is not briding... :-)

Yes, VMS can route packets. Yes, all ethernet interfaces under DECnet
phase IV will have the same MAC address. No, VMS have no idea of the
concept of a bridge. And if you bridge two ethernet segments together,
and VMS sits on both those segments, bad juju happens.

To clarify, before someone complains: all ethernet interfaces *on the same machine* will have the same MAC address.
