- | The vaxes are running either Decnet IV or the new OSI based Decnet.
- | in either case, the Suns won't handle it without some new software.
- | The Sun handles IP and that is it. The four solutions are :
- |
- | 1. Upgrade the vaxes to use tcp/ip.
- | 2. Upgrade the Sun to route the correct Decnet.
- | 3. Replace the Sun with either a bridge or router to handle all
- | protocols.
- | 4. Place a bridge or router in parallel with the sun and have it
- | handle all non IP traffic.
-
- There's one more solution which we use here in similar situations:
- if the VAXen are running MultiNet, then just set up MultiNet to
- encapsulate DECnet IV in TCP/IP. (You also need a friendly
- VAX on the backboneward side of the Sun to pull the DECnet
- out of the TCP/IP packets and route them onward to the
- rest of your DECnet.) A fast, reliable, cheap solution (assuming
- you've already got MultiNet!)
