[HECnet] "Mixed" clustering

[Zane H. Healy]

Why would this leave CHIMPY wihtout an ethernet-based TCP/IP connection? You can use an ethernet interface for clustering, DECnet, and TCP/IP at the
same time.

I've come up with an alternative solution:

I'll use ethernet for the cluster interconnect as I have ethernet ports on all the machines.

However, this leaves CHIMPY without an ethernet-based TCP/IP connection. So my question is this:

Can I hook up two machines (running VMS) with FDDI and have the second machine route packets onto the ethernet segment for me? This wasn't immediately clear from the documentation. I assume if the second machine is set up as a L1 router DECNET over this setup will be possible?

Is it possible to run a cluster over both ethernet and FDDI?
Basically, I'd like to connect Machine A -> B using ethernet and B -> C using FDDI - is this possible?

Unfortunately that configuration violates the rule of full connectivity. All cluster members must have direct connectivity to other members.
But if you add a FDDI-Ethernet-bridge, you should get a "legal" configuration.
