DECnet over GRE tunnel with serial interface

All,

I need help. We have some terminals with one server which run DECnet.
They all reside in the same area (area 1). They work fine when run in
the local segment (by using hub).

I want to exercise one of the terminals connect to the server over the
WAN (by using GRE tunnel) with two cisco routers with back-to-back
serial interafce. I have configured routers with DECnet routing (phase
IV) and assign DECnet cost to tunnel and fast ethernet interfaces.

The problem is, when I do show decnet routing, I see all the the
detailed routing including server and the remaining terminals at the
other side, but when I can't see them by using show decnet neighbor. I
noticed that the SNAP address assigned for tunnel is 0000.0000.0000
which I susspect is the issue when talking to DECnet address format.

Does anyone have suggestion how can I make it working by using GRE
tunnel over back-to-back serial (to simulate a leased line)?

regards


Paris

 

Hi Paris,

Please post the specific DECnet configuration of what you are trying to
accomplish ... router configs, end system addresses etc.
