Ethernet was to be the network for all sites.

Ethernet is a different domain than DECnet routing. You need DECnet routing even with Ethernet. And Alphas can officially act as level 1 routers. It is level 2 (area) routers they supposedly can not be.

AFAIK there is still no DDCMP support for decnet on alpha.

Right.

While it is true that HP does not officially support Alpha's as routers
(according to their web site), it works just fine!

I suspect, but do not know for sure, that this was more of a marketing
ploy to push Itanium over Alpha.

If you go the emulated route (i.e. VAX 3900) this becomes a non-issue as
VAXen ARE supported as DECnet routers.
