Does anyone know how to delete a an ip off the routing table ? i tried route delete 10.0.0.0 and gateway but it still comes back. i have 2 zones sharing one interface. help...
Try to route delete -net 10.0.0.0 and your gateway 
If is "keeps coming back" you might have the wrong netmask(s) in /etc/inet/netmask
also check if you've any rc scripts to auto-startup.
from what zone are you deleting?
