Vicki,
You mention the use of secondary IP's. On a L3 switch (a switch with the
router engine in it) is it not possible to define Ethernet sub interfaces
instead of using secondary IPs - without VLANs defined?
I'm sorry to be so thick, I'm just not getting it. If a L3 switch (with
a routing module/engine in it) is essentially a wire speed router, then the
VLAN just seems like an additional identifier on top of the L3 address - and
doesn't really serve any purpose. In my previous example, 2 hosts on the
same L3 switch, but on 2 different IP subnets - wouldn't a defined Ethernet
subinterface be each clients respective gateway, and thus normal L3 routing
would occur, just at switch speeds????
Thanks again!
