Delete Static Routes on Solaris 10
solaris;ip;route
For the Solaris route command, the delete, and add, sub-commands have the following syntax:  route [ -fnvq ] cmd destination gateway [metric/netmask]So you probably have more success with: route delete 10.250.0.0 10.250.0.37 -netmask 255.255.255.0Or to remove it permanently (as commented by @Alexandre Alves; assuming this was a permanent route):route -p delete 10.250.0.0 10.250.0.37 -netmask 255.255.255.0(Are you sure your netmask is correct for this class A ip-address?)
