Please provide "netstat -nr" and "ifconfig -a" output from the Solaris
system and some basic information about your network. (Is the netmask
really 255.255.0.0? Are all the machines on that network configured
that way?)

That's not going to work. You're telling the system to configure a
non-existent interface, and then plumb it afterwards. That should be:

# ifconfig bge1 plumb 10.1.1.2 netmask 255.255.0.0 \
broadcast 10.1.255.255 up

Or, equivalently, and more concisely:

# ifconfig bge1 plumb 10.1.1.2/16 broadcast + up
