I think you can have several routes with the "b" flag.

You will want to declare "FBB" as an broadcast address in ax25ipd.conf.
FBB sends its broadcasts to that address.
That crummy excuse of an protocol, APRS, of course does not have a fixed
destination address (it seems to me it can be virtually anything) in the
broadcasts so I don't think you can ever expect that to work. The only
thing you can do is to use the default route for any APRS data. That
of course means you can only have ax25ipd routing the APRS broadcasts to
_one_ peer.
That's what I think anyway.

Hmm. I'm not sure I follow your explanation. Too many SSID's to keep
record... :-)
Anyway you need to realise that ax25ipd makes its routing decisions solely
by the destination address (callsign) of the AX25 frame. And all routing
decisions are made on a packet by packet basis. This is completely
different from the xNOS AXIP implementation (where AXIP makes transparent
"pipes" between systems and each "pipe" is assosiated to a separate "port"
on each system - callsigns are not involved in the process).
So if you connect from the remote systems, then you can only expect things
to work if the source call at the remote system is vk2tv-3 or vk2tv-6. In
general case that is not going to be so. For example if you run LinuxNode
on the remote systems, the source callsign will be the _user's_ call, not
the system callsign.
I hope I didn't confuse you even more... :)
