hard to answer, without more data on what the subnets for the various
zones are, and what the desired routing is. The global zone's netstat
may show routes that are only accessible from a non-global zone, so the
fact that the routing table is "busy" does not say anything without
more information about the subnet configuration.

For an example, let's say zone1 has a default route using gateway 172.16.1.1 
and zone2 has a default router using gateway 192.168.0.1. If I am logged into 
the global zone, and it needs to send a packet to 10.10.10.10, will it use one 
of the non-global-zone's default route? Looking at /etc/defaultrouter for the 
global zone, it shows the gateway IPs for the two non-global zones, and also 
10.10.10.1 .  when I try to traceroute to 10.10.10.10 it never shows a single 
hop (as if it's not going to any gateway).

So, why am I not getting to 10.10.10.10? And if I removed the other default 
routes in the global zone, will I be damaging the routing for the local zones? 
If I add a static route in the global zone will that be propagated to the 
non-local zones(I wouldn't want that)? If there's a good doc out there that 
explains this, I'd appreciate a pointer to it, or whatever advice you have for 
me.

Thanks,
     Neil
