A small but sometimes significant point -- if you are updating existing TCPIP stuff you should use smitty tcpip and choose "Further configuration" (or use smitty configtcp direct -- not a fastpath I recall easily). Keep smitty mktcip for original setups; especially important with multiple interfaces.
Also, in terms of default routes and odm updates, you can also use chdev on inet0 to make changes (what smitty does anyway AFAIK).
P.
