DECnet-Plus and multiple NICs?

» close window

The Question is:

 
I have an Alpha 2100A cluster (3 nodes) running DECnet/OSI 6.3 ECO 10.
One node has two NIC. I installed an extra NIC, but when I brought the system
 up it could only talk to other hosts on the LAN that were also running
 DECnet/OSI. I could not set host to systems running Phase IV DECnet. Also, I
 could not set host from a pha
se IV system to the system on which I had just added the NIC.
 
I removed the card & this returned the system to normal.
 
Tks, Charles.
 
 

The Answer is :

 
  This would appear to be a configuration problem, but details of the
  configuration and the DECnet node addressing, as well as details of
  the local routing/bridging/switching network, as well as details of
  the adjacencies and errors, will all be of interest.
 
  DECnet Phase IV assumes one connection (station) per network segment,
  and multiple controllers are permitted only when there is no connection
  between the network segments, or when a DECnet router exists between
  the network segments.
 
  Multiple controllers also typically assume the use of host-based routing.
  DECnet Phase IV end-nodes can use only one circuit, while DECnet-Plus can
  use multiple circuits.  Packet route-through -- or having multiple active
  circuits on a DECnet Phase IV host -- require routing.
