well.....if you had vlans between core devices being trunked (VTP) from dist
to core....yes....( I THINK the group will disagree thoough) dist to access
layer you have Multicast domains....yes...HSRP at the dist level yes....not
really at the access...as for the core....yes...also that would work for
redundency
remember it`s not a way to connect buildings together it just helps us
visualise what needs to be done....
>??? Does VLAN config extend to the core? I mean would I in real life ever
config a VLAN over a core to access a device in another building lets
say???.....
CCIE ....my mate says yes CAN be done...but don`t do it...the idea behind
Vlan`s is to seperate trafic .....why have it running across the core..ONLY
if you have say a MAN.....
core will send whatever data you tell it to send...its upto the dist layer
to make the decision of what to send ........(core must be layer 3
though...multiaccess)otherwise it can`t route(i.e send over ATM FR)
More then likely those Applications would be moved or duplicated in a closer

yes ....you would find that apps required in both buildings...duped...i.e
multiple mail servers..
I`m sure that this will be greatly disputed on the list.....but in therory
...as i`ve not done it it COULD be done.....BUt what you SHOULD do is stop
all Vlan`s and the like at the DIST layer
Sorry it`s so vauge...but last time i answered a question like this i was
shot down on the list...
