Bother, what I wanted to see was how the other routers involved would route
as well as the one that is misbehaving.

My thoughts for what they are worth:
1) the routing table is set up for multiple subnets and the ports are
setup for one network.
2) I would have expected ax4 to be network 44.131.161.0/255.255.255.0.
3) I would have expected a secondary IP address on ax4 i.e. ax4 to have
both 44.131.161.242 & 44.131.160.xxx. (Network aliasing) It may be
that enabling network aliasing is all that is needed, you might not
need to actually assign a secondary IP address.
4) the sorting of the routes looks wrong, would have expected sorting by
route netmask and then by destination address. Mind you 2.0.36 also
exhibits the same behaviour, HP-UX & Cisco routers do what I expect,
can not remember what Solaris and Welfleet routers do (6 years of
non-use showing).
One of the side effects I would expect to see with the setup you have is
ICMP redirects. Do you see any?
I would have anticipated IP addresses and netmasks something along these
lines:
gb7ipd 44.131.161.230/255.255.255.0
gb7itg 44.131.160.127/255.255.255.0
gb7va 44.131. y. x/255.255.255.0
the_box ax4:0 44.131.160. x/255.255.255.0
the_box ax4:1 44.131.161.242/255.255.255.0
the_box ax4:2 44.131. y. z/255.255.255.0
the_box ax3 44.131.160. x/255.255.255.0
the_box ax6 44.131. y. z/255.255.255.0
However as all my router experience a practice is on cabled networks
things may have to be done differently on radio. Indeed on cabled systems
have 3 RX's and 1 TX is something I have never seen, RX's & TX's come in
pairs.
I can not take this any further on a practical note as I am running
2.0.36 kernels here and do not have enough gear to put a test rig
together.
