I've seen cases where chdev would not add a redundant route.
smit mkroute uses chdev too. You might try it just for kicks.
You're correct, route add is not persistent, but chdev is.
You should be able to chdev on the fly.
Certain "no" settings or if you run a routing protocol can affect your
routing tables, but not usually your default route.

Subject: [aix-l] default route. how to set. how can it get lost?
Hi, All
I have a server that, for some unknown reason, seems to have lost its
default route. a fellow sysadmin went to the console and re-established
it using a "route add" command. correct me if I'm wrong but won't this
be lost at the next re-boot? how could this have happened? the server is
question is AIX 4.3.3 ML10. on other AIX servers if I enter the command
"lsattr -El inet0" I get a line beginning with "route" followed by an
indication of the correct default route. on the problem machine the
default route shows up under "netstat -rn" but not on "lsattr -El
inet0". am I not supposed to be able to re-establish this on the fly in
the ODM? I thought if I entered a command such as:
chdev -l inet0 -a route=net,,'0','nn.nn.nn.nn' (where nn.nn.nn.nn
is the gateway address)
it should update the ODM with the address. isn't that what
/usr/sbin/mktcpip does under the covers? if I run the chdev command on
the problem server it comes back and says "inet0 changed" but the
display from "lsattr -El inet0" stays the same. what am I missing here?
