[plug] Ethernet Bonding

[Adrian Chadd]

The trouble with retaining the same local MAC is that you'll experience high
ARP churn as the routing device starts seeing the same IP from multiple source
ARP addresses. I forget how you work around this.

Using a link aggregation protocol on the switch -should- tell the switch not
to bounce learnt MAC addresses between both ports and to treat them as an
actual port group, sending traffic to the relevant port based on some pre
determined algorithm. Isn't that good enough for what you're trying to do?
