Does Gig Ethernet conform to the same minimum frame sizes as general
Ethernet ie 64 bytes.If so how does it accomodate late collisions when
running over distances of 2km or more.???
Or is this not relevant as it will be point to point full duplex and
effectively collision free?
I have done the CCDP and it was a waste of time.(do it if you need the
accreditation for your job )
but it will have no relevance to the CCIE. I suggest you get a good Lab book
and command summary and work your way through each lab implementing as many
scenarios as possible debugging the outcome.
What version of code is the Pix running? If 5.3 or higher you can use an ACL
appied inbound on the outside interface. This is much simpler than statics
and conduits.This is a standard ACL format so you can configure for address
ranges(if contigous)

Yes you can. The DHCP requests will have to be routed via the MSFC or an
