I have a SLES 11 SP3 appliance with multiple NICs. I have configured eth1 as DHCP and it receives an address and default gateway from the DHCP server. I then configure eth2 with a static IP address. When I run
the default gateway route for eth1 is removed and replaced with one for eth2. Very strange behavior. I need the default gateway route to remain unchanged when I bring any other interface up.
Here is it's configuration for eth1 /etc/sysconfig/network/ifcfg-eth0:
Note the DHCLIENT_PRIMARY_DEVICE which is supposed to protect the default route.
Here is the configuration for eth2
Thank you for any insight you can provide
