OK, some testing has been done. you have to specify

IPADDR=192.168.0.10
NETMASK=255.255.255.0
NETWORK=192.168.0.0
GATEWAY=192.168.0.1
IPADDR2=192.168.2.10
NETMASK2=255.255.255.0
NETWORK2=192.168.2.0

please note, that you have to specify only one GATEWAY, there can be
only one default gateway active.
