When you did the
ifconfig en0 down
ifconfig en1 down
ifconfig en0 detach
ifconfig en1 detach
rmdev -dl en0
rmdev -dl en1
rmdev -dl ent0
rmdev -dl ent1
cfgmgr
the gateway should have been gone........(especially when the rmdev -dl on the card ent0 and ent1) It is the card that holds the gateway as well as the /etc/rc.net file
How do you tell if a route is in the ODM or not (besides rebooting to see if it comes back)?
lsattr -El inet0
To establish a default gateway, enter: (but not in odm. add rc.net file.)
route add 0 192.100.13.7
route delete 0 192.100.13.7
or the chdev command should delete as well..........easiest is delete the card and redefine it in smit
Some have said that if you blank it out in the smitty minimum config and run it, it goes away...I have not had much luck with this......... worth a try I guess.
