[TriLUG] [BGLUG] problems with multiple interfaces on a RHEL5.5 x64 machine

[David Black]

Still not knowing what problem is solved/purpose served, the following would probably do the job, while avoiding the reported issues and confusion over what is supposed to happen:

1. Set up a single layer-2 bonded interface, e.g. eth1 + eth2 -> bond0
2. Put the static IP address on bond0, and the secondary IP address on bond0:0

This also has the benefit of allowing both addresses to share 2x the bandwidth (depending on bonding mode of course), and the alias going up and down won't bounce any physical interface.
