=ping: sendto: Can't assign requested address= in fib spaces

[Alan Somers]

That "Can't assign requested address" suggests that the problem might
have nothing to do with fibs.  Can you show us your "ifconfig" output?
 It would also help to know what local address ping is trying to
assign.  You can figure that out by doing "setfib 2 ktrace ping
8.8.8.8; kdump" and searching for "bind".  Once you know that, you can
try playing with ping's "-S" option to set different local addresses.
