Re: eth1 and eth2 Breaks Default Route

There was a typo in the original message. The
correction follows:
A buddy of mine asked the following question on
comp.os.linux.networking, but those folks don't fully
understand why an interface would want to be set to
0.0.0.0/0. If anyone can shed some light on a fix, I'd
like to know. Here's the original question:
I have Red Hat 9 on an X86 with three (3) interfaces
working as an IDS. eth0 is my management interface
with a live IP address. eth1 and eth2 both have their
IP addresses set to 0.0.0.0/0 for data collection.
All IP addresses are set in
/etc/sysconfig/network-scripts/ifcfg-eth?.
When the box boots up my default route is shot through
eth2 (should be eth0) even though I have my GATEWAY
keyword set to the gateway I want. The following are
my ifcfg-eth? entries:
/etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
onfiltered=yes
BOOTPROTO=static
IPADDR=1.2.3.4
NETMASK=255.255.255.0
GATEWAY=1.2.3.1
/etc/sysconfig/network-scripts/ifcfg-eth1
DEVICE=eth1
BOOTPROTO=static
BROADCAST=255.255.255.255
IPADDR=0.0.0.0
NETMASK=0.0.0.0
NETWORK=0.0.0.0
onfiltered=yes
GATEWAY=1.2.3.1
/etc/sysconfig/network-scripts/ifcfg-eth2
DEVICE=eth2
BOOTPROTO=static
BROADCAST=255.255.255.255
IPADDR=0.0.0.0
NETMASK=0.0.0.0
NETWORK=0.0.0.0
onfiltered=yes
GATEWAY=1.2.3.1
I added "GATEWAY=1.2.3.1" to ifcfg-eth1 and ifcfg-eth2
to see if that would fix things. It doesn't...
Q1: How do I get the system to recognize the proper
gateway as specified in ifcfg-eth0?
Q2: Is there a way to tell an interface to boot in
promiscous mode? I'm thinking there is a keyword that
can be placed in ifcfg-eth?, but I can't find any
reference to that...
