Routing via aliased interfaces in RHEL


Hi all,

I am having following problem.

RHEL 5.5 won't accept specifying an aliased interface (e.g. eth1:0) when I add a new host route to the routing table of a machine with multiple Ethernet interfaces. I have read that this works with Ubuntu, but RHEL gives problems. It only understands the interface card (e.g. either eth0 or eth1, but does not understand the aliased virtual interfaces within say eth0 or eth1)

Any input would be appreciated
