[HECnet] Any DECnet Routing Protocol Experts Out There?

[Rob Jarratt]

I found a bug in my adjacency processing that made other adjacencies use
index 0 in the decision database, I think that is what has been causing the
Check failures.

You process address 0 exactly as any other level 1 routing message entry.

Then in the forwarding process of an L1 router, if the destination is out
of
area, use entry 0 to decide how to forward the packet.

Why do you get failures from Check?   I don't see how you could get that.

I am working on a user mode DECnet router and I have a question about the
Level 1 Routing message.

Specifically, sometimes I receive a level 1 routing message with routing
information for destination address 0. The spec says this represents the
"nearest level 2 router". What I am not clear about is how this is
supposed
to be treated in the Decision Process, specifically Section 4.7.3 item F
in the
specification. The reason I ask is that if I blindly accept address 0 I
think it
corrupts the hop and cost tables, because the Check process then gets
failures.
