If you have different switches for each line i suggest the use
of "bonding" in balance-round-robin mode.
+-------+ eth0 +--------+ eth0 +------+
| Host |--------|switch 1|--------| Host |
| | +--------+ | |
| A | eth1 +--------+ eth1 | B |
| |--------|switch 2|--------| |
+-------+ +--------+ +------+
See /usr/src/linux/Documentation/networking/bonding.txt

Paul
