[K12OSN] LTSP server with 3 NICs?

[Paul VanGundy]

Terrell,

Ok. I specifically mentioned layer 3 routing because it can do inter
VLAN routing where as layer 2 routing can not do inter VLAN routing
(ie Cisco 3750s can while 2950s can not). Inter VLAN routing is what
you may (or may not) want when segmenting a network.
