- I have to disagree slightly here. The upper level DECnet
- protocols are easily routable, but the device management
- protocols (pre-phase V) such as MOP are not. You're stuck with
- tunneling or (worse yet) deploying remote hosts to do small tasks
- like download microcode into printers. I'm anxiously awaiting a
- full phase V implementation which is rumored to correct this
- problem, as well as introducing a routable LAT and (I hope) the
- demise of MOP in favor of SNMP or something else that will deal
- with routed networks in a more congenial fashion.
