[HECnet] Any DECnet Routing Protocol Experts Out There?

[Paul_Koning at Dell.com]

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.

Thanks
