[HECnet] DECnet et al

Ok, so the convention that the output of the SHO NET command always lists the area router with the highest address is just a display rule. It has nothing to do with an "active" area router then?

As far as I know, there can be more than one active area router. Just look at what the next hop are for different nodes in your node list... :-)

The way it works is that address 0 in the level 1 routing data corresponds to "nearest L2 router".   Any L2 router contributes to that.   The L1 routers don't know or care who is the nearest L2 router, they only care which direction to send to get there.
