| Strange network issue with two default gateways
Hi there,
restored a box from mksysb. The machine has three network adapters but I
just need one. Booting up, en2, et0, and et0 are configured and up. This
is not wanted so I detached et0 and en2. Just en0 left up and running.
netstat -r gives a default gateway that points to the local interface.
Therefore the machine cannot be reached - it is connected to a
Layer-3-Switch. Then I tried smitty tcpip -> minimum configuration ->
en0, all information entered, ENTER and the config was saved. Now I had
two default gateways, the first pointed to the local machine, the second
to the router. Removed the first default gateway using `route delete 0
<hostname>`. Now netstat -r is OK, traffic flows. Some days later one of
my operators rebooted the machine. And the same story starts from the
beginning: en2, et0 are there again, netstat -r shows two default
gateways, if running `route -f` just one entry remains with localhost as
default route.
Why is that? Is the only way to overcome this to remove all devices from
the ODM?
