All on the same physical LAN.  This is possible due to Adaptive Load Balancing.  The
nics aren't teamed in the respect of total throughput, but rather in the respect that
they can handle their own set of commands and traffic.  Below is a description on ALB:

mode=6

Adaptive load balancing: includes balance-transmit load balancing plus receive load
balancing for IPV4 traffic, and does not require any special switch support. The receive
load balancing is achieved by ARP negotiation. The bonding driver intercepts the ARP
Replies sent by the local system on their way out and overwrites the source hardware
address with the unique hardware address of one of the slaves in the bond such that
different peers use different hardware addresses for the server.
