True, they operate on IP layer, whereas your team is, apparently, rather convinced to use the transport layer for network discovery. This is an area where I can't really help with solution, hopefuly someone else will. Initially, I thought that you could do something like controlled nmap scan of your network segments, and based on results to start an application like traceroute, ping or other to verify the results and write the report somewhere , in some format, but it seems that you need more than that, so like I said, hopefully someone else will join the thread with more insight.

NRBROADCAST(5)						     Linux Programmer's Manual						    NRBROADCAST(5)

NAME

       nrbroadcast - NET/ROM routing broadcast configuration file.

DESCRIPTION

       Nrbroadcast  is	an ASCII file that contains information about each of the physical AX.25 ports that are to have NET/ROM routing broadcasts
       transmitted from them.

       Each line has the following format, each field being delimited by white space:

	      port minobs defqual worstqual verbose

       The field descriptions are:

	      port	    the port name of the AX.25 port to broadcast on.

	      minobs	    this is the minimum obsolescence count of a routing table entry to be broadcast on this port.

	      defqual	    this is the default quality of an incoming routing broadcast from an unknown neighbour.

	      worstqual     this is the worst quality node received from a routing broadcast that will be added to our routing table.

	      verbose	    whether the routes to all of my nodes in my routing table, or just the nodes resident on my machine are to	be  broad-
			    cast.

FILES

       /etc/ax25/nrbroadcast
