Routing Virtual IP address


Hi everyone.

I have a RHEL 5 system with this configuration:

eth0=192.168.0.10

eth0:1=192.168.1.10
eth0:2=192.168.0.11

I remove the default gw for eth0:1 because I have problems when I mount anothe NFS file system belong to 192.168.0.x vlan.

my routing table showme something like this:

Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.1.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0
192.168.0.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0
169.254.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth0
0.0.0.0 192.168.0.1 0.0.0.0 UG 0 0 0 eth0


I know if I use route command I can routing, e g NFS that use 192.168.0.x IP to the 192.168.0.10 and another services to 192,168.1.10.

How can I do this...
Thanks

Moved: This thread is more suitable in Linux-Networking and has been moved accordingly to help your thread/question get the exposure it deserves.

eth0:0 and eth0:1 are two interfaces at relatively high level - everywhere below they're one. It produces problems from time to time, but I don;t think it's your case. The thing is that, when it comes to the gateway, there may be only one default gateway in one routing table. More are possible to enter, but it won't work as expected.

What are you trying to archive?

Thanks Mara for move my question.


This server have 3 different names on DNS, the ETH0 is for Server communication ( NFS, syslog, etc) the ETH0:1 have another hosname on DNS, this is for Client communication (SAP) and ETH0:2 (another hostname for SAP messages).

This is the reason that I need routing through this virtual IPs.

Thanks
